No status page, SLA or security.txt, breaking v1 changes shipped in October with same-day notice, the server is at 0.10.7, and the index covers the shows Arcmira transcribes.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Arcmira, Inc. (https://arcmira.com) |\n| Kind | MCP server |\n| Category | Web search APIs (https://www.anchorterminal.com/categories/search) |\n| Transport | Streamable HTTP, HTTP |\n| Endpoint | `https://mcp.arcmira.com/mcp` |\n| Auth | OAuth or key · The MCP server at https://mcp.arcmira.com/mcp answers an unauthenticated request with 401 and OAuth protected-resource metadata; hosts sign in through api.arcmira.com with the authorization code flow, PKCE S256, dynamic client registration and refresh tokens, and the consent screen grants read access plus, if allowed, monitor changes (scopes read, monitors:write, trackers:write, recommendations:read). Any client can instead send an account key as `Authorization: Bearer arc_sk_...`. Dashboard keys carry all four scopes and show once; a key minted from `POST /v1/signups` and `/v1/signups/verify` (an email and a six-digit code, no browser) carries `read` only and never expires. Keys are disabled on the API keys page and take effect at once; hosts are revoked under Dashboard, Integrations. Plan gates, not scopes, decide Premium transcripts, fresh media and sponsor rows. |\n| Pricing | Freemium ($0.001 / credit) · Free plan with 1,000 credits a month, 2 monitored names and no card, which withholds the newest 30 days of media and the pages past the first. Pro $20 a month for 20,000 credits (7-day trial, card required), Pro+ $60 for 60,000 with sponsor and recommendation rows, Ultra $200 for 400,000, Enterprise by contract; yearly billing 20 per cent less. A search passage, mention or list row costs 4 credits past the first 5 of a request, a momentum call 10, a sponsor row 40, a monitor alert 25, captions 4 per started 15 minutes and a Premium transcript 300 per started 15 minutes of the whole video, once. Past the plan, on-demand usage costs $0.002 a credit up to a budget an admin sets; repeating a request within 7 days and failed Premium transcripts cost nothing (https://arcmira.com/docs/usage-and-billing.md, checked 2026-10-30). |\n| x402 | No · No x402, MPP or L402 in the OpenAPI file, llms.txt, developers.md, the docs or the pricing page (checked 2026-10-30). Paid plans and on-demand usage are billed to a card through Stripe from the dashboard. |\n| Licence | Proprietary service under Arcmira's Terms of Service. The MCP server's source is public under an all-rights-reserved notice; the Claude Code plugin, the arcmira TypeScript SDK and CLI and the Python SDK are Apache-2.0, and the Famous rankings are CC BY 4.0 |\n| Tools exposed | 4 |\n| Packages | npm: `arcmira`; pypi: `arcmira` |\n| MCP registry name | `io.github.arcmira/arcmira` |\n| Source | https://github.com/arcmira/mcp |\n| Docs | https://arcmira.com/docs |\n| llms.txt | https://arcmira.com/llms.txt |\n| Last release | 2026-10-15 |\n| GitHub stars | 78 (as of 2026-10-30) |\n| Surface listed | The remote MCP server at https://mcp.arcmira.com/mcp, with the REST API at https://api.arcmira.com/v1, the arcmira CLI and the TypeScript and Python SDKs it fronts, read from llms.txt, developers.md, auth.md, the docs' markdown twins, the OpenAPI file, the legal pages, the arcmira/mcp repository (shallow clone), the GitHub API, the MCP registry, npm and RDAP on 30 October 2026. No account was created, no API call or MCP session was made and no OAuth client was registered; the server card and the OAuth metadata documents were the only reads from mcp.arcmira.com and api.arcmira.com beyond the OpenAPI file |\n| Kind | Listed as `mcp` because the docs quickstart, the home page and the docs index lead with connecting an agent to mcp.arcmira.com, the registry entry and the repository are the server, and the MCP page is the first product page. The HTTP API is the same surface with the same credits; the OpenAPI file and the SDKs are described here and graded where the checklist reads the API |\n| Tools | arcmira_describe (readOnlyHint true, idempotentHint true; optional `topic` narrows the reference), arcmira_execute_read (a JavaScript program against GET /v1/*; readOnlyHint false, destructiveHint false, openWorldHint true), arcmira_execute_write (adds POST and PATCH under /v1/monitors and PATCH /v1/trackers, never DELETE; destructiveHint true), arcmira_feedback (POST /v1/feedback with an enum category, a note and optional request_id and call_id). Every tool takes an optional `intent` of at most 300 characters that is logged. Retired names (describe, execute, prepare_transcript and the ten pre-0.7.0 tools) answer `tool_retired` naming the replacement |\n| Program limits | 30 seconds, 5 seconds of CPU, 40 API calls (`call_budget`), 12,000 characters of output in total, 3,000 per string and 100 items per array. A Premium read waits up to 22 seconds of the program's time. Results carry `_meta['arcmira.com/execution']` with the call count, routes, API build and rate limit, and `isError` on a failed program |\n| API | OpenAPI 3.1.0, version 1.0.0, 31 paths and 35 operations (23 GET, 7 POST, 3 PATCH, 2 DELETE) under /v1, 75 component schemas, one bearer scheme with format `arc_sk_*`. Groups are Meta (health, openapi.json, me, me/settings, signups), Entities (resolve, entity, momentum), Search, Mentions (mentions, counts), Channels (sponsors, coverage, videos), Recommendations, Transcripts (transcript, quote), Transcriptions, Monitors (10), Trackers (4) and Feedback (2). The same document is served at https://arcmira.com/docs/openapi/arcmira-v1.json |\n| Credentials | OAuth authorization code with PKCE S256, dynamic client registration at api.arcmira.com/api/auth/oauth2/register, refresh tokens, introspection and revocation endpoints, DPoP algorithms advertised, scopes openid, profile, email, offline_access, read, recommendations:read, monitors:write and trackers:write; access tokens last an hour and refresh for 30 days. Keys `arc_sk_` as a bearer header only, shown once, labelled, listed with maker and last use, disabled at once. Sign-up keys carry `read` and never expire. In a team a credential acts in the account it was made in |\n| Rate limits | 60 requests a minute per key on Free, 240 on paid plans, 600 on Enterprise, counted per Cloudflare location, with `RateLimit-Limit`, `RateLimit-Remaining` and `RateLimit-Reset` headers. 429 `rate_limited` with `Retry-After` and `retry_after_seconds`; 30 bad-key requests a minute from one address lock that address for the minute. Sign-up codes are capped at 3 per address, 10 per IP an hour and 25 per client a day |\n| Errors | One envelope with `type`, `code`, `message`, `param`, `gate`, `resource`, `unlock` (tier, url, offer, action), `details` (quote, limit), `retry_after_seconds`, `doc_url` and `request_id`. HTTP 400, 401 (with `reason`), 402, 403, 404, 409, 410, 429, 500 and 503. About 60 codes documented with a fix each; 402 refusals charge nothing and carry the refused price |\n| Pagination and filters | `limit` and `cursor` with `has_more` and `next_cursor` on lists, a signed cursor bound to the route and caller; search `limit` 1 to 20 (default 5), `after` and `before` half-open windows, `about` (up to 8 entity ids), `by`, `kind`, `channel_ids`; `start` and `end` on transcripts; monitor and tracker alert lists are one page of up to 100. Free returns the first page only and media older than 30 days; anonymous entity markdown older than 60 days |\n| Monitors and webhooks | Monitors hold trackers (2 on Free, 10 Pro, 30 Pro+, 200 Ultra) with email, Slack and webhook delivery; alerts cover episodes published in the last 14 days and cost 25 credits each. Webhooks need a paid plan, return a `whsec_` secret once, sign `{timestamp}.{raw body}` with HMAC-SHA256 as `X-Arcmira-Signature`, carry `X-Arcmira-Timestamp` and `X-Arcmira-Event`, turn off after ten failures, and rotate with a 24-hour `X-Arcmira-Signature-Previous` overlap |\n| SDKs and CLI | npm `arcmira` 0.6.2 (15 October 2026, Apache-2.0, 15 versions since 0.1.0 on 22 August, Node 18 and later, Workers, Deno, Bun and browsers, no runtime dependencies) is the TypeScript client and the `arcmira` CLI, whose exit codes are 1 API error, 2 usage error and 4 Premium transcript pending; `npx arcmira setup` adds the MCP server and skills to Claude Code, Codex, Cursor, VS Code, Gemini CLI and Claude Desktop. PyPI `arcmira` is the Python client (repository github.com/arcmira/python at v0.6.2, Apache-2.0); the PyPI page served a bot check. A Claude Code plugin from the repository bundles the server and six skills |\n| Credits | Free 1,000 a month; Pro 20,000 for $20 ($0.001 a credit); Pro+ 60,000 for $60; Ultra 400,000 for $200 ($0.0005); on-demand $0.002 a credit up to an admin-set budget, invoiced in steps from $20. First 5 passages, mentions, count rows and videos of a request free; 4 each after; momentum 10; sponsor or commercial row 40 (Pro+); alert 25; captions 4 per started 15 minutes; Premium 300 per started 15 minutes of the whole video, once per account and language. Resolve, /v1/me, quotes, owned Premium reads, feedback and creating monitors cost 0; a repeated request within 7 days costs 0; a failed Premium transcript is refunded |\n| SLA | None found. The terms disclaim uninterrupted, timely, secure or error-free service, and the Enterprise page lists higher limits, an activity log and priority support with a dedicated account manager, priced per contract |\n| Data handling | Privacy policy effective 2 October 2026. Retention for as long as necessary with no periods; closed accounts are deactivated and limited usage and billing records kept. Session replay with masked form fields, no advertising trackers, private account data not used to train general models, US processing and other locations.

Documented the same day with typed codes, a 410 and a migration table, so deducted at the low end (-3). https://arcmira.com/docs/changelog.md | -3 |\n| **Total** | | | | **64.2 → B** |\n\n### Why each score\n\n- Reliability 40 (checked 2026-10-30): Hosted reading, for the MCP server with the HTTP API it fronts. No public status page was found. None is linked from the docs, llms.txt, developers.md or the footer, https://arcmira.com/status answers 403 and status.arcmira.com does not answer (0). No readable incident history, so the floor (5). Limits are published with numbers on the Plans and usage page, 60 requests a minute per key on Free, 240 on paid plans and 600 on Enterprise, with RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset on every authenticated response and a 30-a-minute cap on bad keys per address (15). 429 rate_limited carries Retry-After and retry_after_seconds, developers.md asks for exponential backoff, 503 search_unavailable and transcript_fetching carry Retry-After, every POST and PATCH takes an Idempotency-Key that replays with Idempotency-Replayed, a repeated Premium read is never charged twice, and a webhook secret can be recovered under its key for 24 hours (15). No SLA. The terms (effective 13 October 2026) disclaim uninterrupted or error-free service, and the Enterprise page lists priority support but no uptime commitment (0). The HTTP API is /v1 at document version 1.0.0 with nothing labelled beta, but the MCP server agents connect to is 0.10.7 after 30 registry versions in six weeks, two rounds of tool renames and a retired-tool error for stale hosts, and chat is in beta (5 of 10). 0+5+15+15+0+5 = 40.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 87 (checked 2026-10-30): MCP reading, with the API the tools call. A public OpenAPI 3.1 file at api.arcmira.com/v1/openapi.json (31 paths, 35 operations, 75 schemas, one bearer scheme, also served at arcmira.com/docs/openapi/arcmira-v1.json), and the four tools declare zod input schemas in src/tools.ts (25). llms.txt routed by situation, a .md twin of every docs page, developers.md, auth.md, a published Agent Skill, an RFC 9727 api-catalog and a .well-known/mcp card (10). Tool descriptions say what each does, that arcmira_describe is called once and bills nothing, that the write tool never deletes and when to send feedback; operation descriptions in the OpenAPI file say to call coverage before claiming a show isn't indexed and to resolve names before filters, and the server instructions carry the id rule, the 90-day default and the usage rule. When not to use a method is covered by the id rule and the resolver note, little else (16 of 20). The two execute tools take a JavaScript program as one string, checked only when it runs; the feedback tool has an enum category, a regex call_id and length caps; the API has 102 parameters, 37 with enums, ranges or patterns, and ids typed by prefix (9 of 15). Worked example programs in the reference, curl examples on every guide, an error catalogue of about 60 codes with a cause and fix each, doc_url anchors and request ids on every error, and typed unlock and details.limit objects; only 9 parameters in the OpenAPI file carry an example (14 of 15). /v1 in the path, a dated docs changelog from April 2026 with a 14-row table for the 5 to 8 October breaking changes, a per-version CHANGELOG.md in the repository and 30 registry versions; the OpenAPI file marks retired fields deprecated, but the quickstart says new fields and routes arrive without notice and nothing states a notice period (13 of 15). 25+10+16+9+14+13 = 87.\n- Agent ergonomics 91 (checked 2026-10-30): MCP reading. Four tools whose definitions are short, but arcmira_describe returns a reference the vendor measures at 23,124 characters, loaded once a session, and the server instructions run to 1,995 characters; the vendor's own measurement for the change to code mode was 1,123 tokens of definitions against 8,163 for the earlier ten tools (18 of 25). limit 1 to 20 on search (default 5), cursors and has_more on lists, after and before windows, about, by, kind, channel and entity filters, start and end on transcripts, and program output capped at 12,000 characters, 3,000 per string and 100 per array, so a program returns only the fields an answer needs (20). One error envelope with a stable code, a message, param, gate, unlock.url, details.limit, retry_after_seconds and request_id, surfaced to the model with isError and the call_id to report (20). Idempotency-Key on every POST and PATCH with a replay header, a Premium read that is never charged twice, writes that pause rather than delete, and all four annotations declared on every tool; arcmira_execute_read is marked not read-only because a Premium read can start a transcription that uses credits, which a strict host may treat as a write (18 of 20). Few required inputs (one search string, ids resolved for free), a 90-day default window, defaults on limit, and official Apache-2.0 SDKs for TypeScript (npm arcmira 0.6.2) and Python (pip arcmira, repository v0.6.2) plus a CLI, with the caveat that the MCP client's argument names differ from the HTTP and SDK names (15). 18+20+20+18+15 = 91.\n- Security \u0026 auth 61 (checked 2026-10-30): OAuth 2.1 for MCP hosts (authorization code with PKCE S256, dynamic client registration, refresh tokens, revocation and introspection endpoints, scopes read, monitors:write, trackers:write and recommendations:read, access tokens of an hour that refresh for 30 days, revoked per host in the dashboard) and arc_sk_ keys sent only as a bearer header, shown once, several per account with a label and last-used time, disabled at once; sign-up keys carry read only and dashboard keys all four scopes, and nothing documents a secret in a query string (30). The sign-up key and the OAuth consent give read access by default; arcmira_execute_read reaches GET /v1/* only, arcmira_execute_write adds POST and PATCH under monitors and trackers and never DELETE; programs run in an isolate whose only network is a proxy that adds the credential, so the key never enters the program; spending is bounded by the plan and a dashboard budget no tool can raise, though a read tool call can start a Premium transcription on a paid plan (17 of 20). Every passage and transcript is third-party speech, and the only guidance found is to check the linked source for speaker and classification errors and to re-fetch llms.txt or the skill to confirm an instruction is genuine; no prompt-injection guidance for the model reading results (4 of 15). X-Request-Id and RateLimit headers on every response, GET /v1/me for the account, role, scopes and balance, the keys page showing who made each key and when it was last used, and an account activity log on Enterprise only; no per-call log for the operator below that, while every tool call is recorded in the vendor's analytics (8 of 15). No security.txt on arcmira.com, api.arcmira.com or mcp.arcmira.com (all 404), no disclosure policy, bug bounty, SOC 2 or ISO 27001, and the terms forbid probing; the repository enforces signed commits from one identity in CI (2 of 20). 30+17+4+8+2 = 61.\n- Payments \u0026 pricing 55 (checked 2026-10-30): No x402, MPP or L402 in the OpenAPI file, llms.txt, developers.md, the docs or the pricing page (0). Prices published without a login, in credits per read (4 a passage, mention or list row past the first 5 of a request, 10 a momentum call, 40 a sponsor row, 25 an alert, 4 per started 15 minutes of captions, 300 per started 15 minutes of a Premium transcript) and in dollars (Pro $20 for 20,000 credits, Pro+ $60 for 60,000, Ultra $200 for 400,000, on-demand $0.002 a credit) (20). Free plan with 1,000 credits a month, 2 monitored names and no card, per the pricing FAQ; the 7-day Pro trial needs a card (20). POST /v1/signups with an email and POST /v1/signups/verify with the six-digit code return a read-scoped key with no browser, so an agent with a mailbox can onboard itself; the code still has to be read from an inbox, and write scopes need a dashboard key or OAuth consent (15 of 20). 0+20+20+15 = 55.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 84 (checked 2026-10-30): The MCP server's newest release is 0.10.7, published to the registry on 12 October 2026 and to GitHub on 15 October, with repository commits to 30 October; the SDKs reached 0.6.2 on 15 October and the last dated API change in the docs changelog is also 15 October (30). 30 registry versions from 0.3.0 on 4 September to 0.10.7, 24 GitHub releases, 15 npm versions of arcmira since 22 August and 10 dated docs changelog entries in October (20). Issues on arcmira/mcp are mostly the maintainer's own (18 of 19 items are their own pull requests or notes); the one outside issue, #13 of 18 October, had no reply by 30 October; support is an email address, hi@arcmira.com, and a free feedback endpoint whose review states can be read back; no Discord, forum or community channel (11 of 25). io.github.arcmira/arcmira is in the official MCP registry under the GitHub-verified organisation namespace, current at 0.10.7, and the TypeScript and Python SDKs are current (15). CI on every push and pull request (typecheck, tests, manifest check against the OpenAPI contract, signed-commit check) passing on master on 30 October, pinned dependencies and a lockfile; the server itself is not a package anyone installs, so package health is the SDKs', whose CI we didn't read (8 of 10). 30+20+11+15+8 = 84.\n- Transparency \u0026 trust 61 (checked 2026-10-30): Closed service under terms effective 13 October 2026 that name Arcmira, Inc., San Francisco, California law and AAA arbitration; the MCP server's source is public under an all-rights-reserved notice, while the plugin, the TypeScript SDK and CLI and the Python SDK are Apache-2.0, and the Famous rankings are CC BY 4.0 (18 of 30). The privacy policy (effective 2 October 2026) states no retention periods, keeps limited usage and billing records after an account closes, discloses session replay and that private account data isn't used to train general models, and the MCP docs and README disclose that every tool call, including the first 4,000 characters of a program and the agent's intent, is logged to product analytics with credentials redacted and no opt-out; no DPA was found, and the terms' section 7A bars bulk use and model training on Arcmira data (14 of 30). Retirements are dated and typed in the changelog (POST /v1/trackers to 410 tracker_create_retired on 8 October, tool renames answering tool_retired), but the terms allow changes with or without notice, the quickstart says routes arrive without notice and no notice period is stated (8 of 20). The policy names service-provider categories (hosting, payment, analytics, AI processing) and US processing with other locations, and the docs name PostHog, Stripe, Cloudflare and Mintlify, but there is no subprocessor list and no data-location statement beyond the US (8 of 20). 18+14+8+8 = 48.\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (25 items): https://www.anchorterminal.com/fixes/arcmira.md (JSON https://www.anchorterminal.com/fixes/arcmira.json)\n\n### What we couldn't check\n\n- Kind is `mcp`. The docs quickstart, home page and docs index lead with connecting an agent to mcp.arcmira.com, the registry entry and the repository are the server and /mcp is the first product page, so the server is graded as the main surface and the HTTP API, CLI and SDKs are described alongside it. The API reading of each checklist line would move little, since the limits, errors and idempotency rules are the API's.\n- unchecked: the live tools/list, the server's protocol behaviour and the size of the arcmira_describe reference in tokens. No MCP session was opened; the four tools, their annotations and schemas are read from src/tools.ts at the 30 October master, which package.json says is 0.10.7, and from the server card.\n- unchecked: whether an API sign-up or OAuth flow works as documented. No account was created, no code requested and no client registered. The one unauthenticated GET to /mcp is the 30 October listing check's.\n- unchecked: the PyPI page for arcmira, which served a bot check. The Python SDK's version and licence are read from github.com/arcmira/python (v0.6.2, Apache-2.0).\n- unchecked: whether a status page exists under another name. None is linked from any page read, https://arcmira.com/status answers 403 and status.arcmira.com does not answer, so it is scored absent.\n- unchecked: the hosted server's deployed version. The registry's latest is 0.10.7 of 12 October; the repository's master has later commits (docs, listing proofs, plugin links) without a version bump, and the CHANGELOG says a 0.10.8 change was reverted so the server stays on 0.10.7.\n- firstReleased is 2026-08-22, the first npm publication of arcmira and the start of the SDK repository's history. The vendor's changelog dates the first public API to April 2026 and a v1.1.0 to May 2026 without days, so the API is older than that date; the MCP server's first registry version is 4 September 2026. The batch file suggested the registry date; the npm date is earlier and first-hand.\n- The vendor's index size, 'search engine for the spoken web' and 'SF-based' are the vendor's claims; the terms name Arcmira, Inc. in San Francisco. The 'Used by people at' logos on the pricing page (OpenAI, PlanetScale, TBPN, T3, Convex, Rainmaker) are unverified claims.\n- The MCP registry's 0.7.x descriptions mentioned code mode; the repository's 0.7.0 entry (29 September 2026) describes it as ten tools replaced by describe and execute over a typed client, with the vendor's own measurement of 1,123 tokens of definitions against 8,163 and 59 of 60 tasks against 56. Those are the vendor's figures.\n- The sign-up route sends a six-digit code by email, so autonomous onboarding is scored 15 of 20 rather than 20. A mailbox-equipped agent can complete it; one without cannot.\n- The 8 October v1 changes are deducted -3 as a breaking change with same-day notice. The vendor's position that the API is v1 without a versioning or deprecation policy is recorded in transparency; a published notice period would lift both.\n- GitHub shows the arcmira/mcp repository created on 12 October 2026 with commit history from 28 September and 23 of its 24 releases published that day and 0.10.7 on 15 October, so the earlier registry versions were published from a repository that wasn't public. Recorded, not deducted.\n- Arcmira doesn't do LocalGhost's or letme's job. It returns transcript passages, mentions and sponsor data for an agent to cite; it neither hides an agent's identity nor chooses tools for a task.\n\n### Sources\n\n- llms.txt, site index by situation: \u003chttps://arcmira.com/llms.txt\u003e (seen 2026-10-30)\n- developers.md, the API on one page: \u003chttps://arcmira.com/developers.md\u003e (seen 2026-10-30)\n- auth.md, credential runbook: \u003chttps://arcmira.com/auth.md\u003e (seen 2026-10-30)\n- docs index for agents: \u003chttps://arcmira.com/docs/llms.txt\u003e (seen 2026-10-30)\n- quickstart and HTTP conventions: \u003chttps://arcmira.com/docs/index.md\u003e (seen 2026-10-30)\n- MCP server docs (tools, annotations, limits, logging): \u003chttps://arcmira.com/docs/mcp-server.md\u003e (seen 2026-10-30)\n- keys and sign-in, scopes: \u003chttps://arcmira.com/docs/authentication.md\u003e (seen 2026-10-30)\n- plans, credits, on-demand budget, rate limits: \u003chttps://arcmira.com/docs/usage-and-billing.md\u003e (seen 2026-10-30)\n- errors catalogue: \u003chttps://arcmira.com/docs/errors.md\u003e (seen 2026-10-30)\n- monitors and webhook signing: \u003chttps://arcmira.com/docs/monitors.md\u003e (seen 2026-10-30)\n- transcripts: \u003chttps://arcmira.com/docs/transcripts.md\u003e (seen 2026-10-30)\n- search guide: \u003chttps://arcmira.com/docs/search.md\u003e (seen 2026-10-30)\n- sponsors and recommendations: \u003chttps://arcmira.com/docs/commercial-intelligence.md\u003e (seen 2026-10-30)\n- CLI and SDKs: \u003chttps://arcmira.com/docs/libraries.md\u003e (seen 2026-10-30)\n- documentation MCP: \u003chttps://arcmira.com/docs/documentation-mcp.md\u003e (seen 2026-10-30)\n- feedback and support: \u003chttps://arcmira.com/docs/feedback.md\u003e (seen 2026-10-30)\n- teams, members and Enterprise: \u003chttps://arcmira.com/docs/teams/enterprise.md\u003e (seen 2026-10-30)\n- docs changelog: \u003chttps://arcmira.com/docs/changelog.md\u003e (seen 2026-10-30)\n- OpenAPI 3.1 file: \u003chttps://api.arcmira.com/v1/openapi.json\u003e (seen 2026-10-30)\n- pricing page: \u003chttps://arcmira.com/pricing\u003e (seen 2026-10-30)\n- MCP product page: \u003chttps://arcmira.com/mcp\u003e (seen 2026-10-30)\n- agent setup hub and prompt: \u003chttps://arcmira.com/agent-setup\u003e (seen 2026-10-30)\n- Terms of Service: \u003chttps://arcmira.com/terms\u003e (seen 2026-10-30)\n- privacy policy: \u003chttps://arcmira.com/privacy\u003e (seen 2026-10-30)\n- Famous rankings licence: \u003chttps://arcmira.com/famous/license\u003e (seen 2026-10-30)\n- Agent Skill: \u003chttps://arcmira.com/.well-known/skills/arcmira/SKILL.md\u003e (seen 2026-10-30)\n- MCP discovery card: \u003chttps://arcmira.com/.well-known/mcp\u003e (seen 2026-10-30)\n- api-catalog linkset: \u003chttps://arcmira.com/.well-known/api-catalog\u003e (seen 2026-10-30)\n- MCP server card: \u003chttps://mcp.arcmira.com/.well-known/mcp/server-card.json\u003e (seen 2026-10-30)\n- OAuth protected resource metadata: \u003chttps://mcp.arcmira.com/.well-known/oauth-protected-resource\u003e (seen 2026-10-30)\n- OAuth authorization server metadata: \u003chttps://api.arcmira.com/.well-known/oauth-authorization-server\u003e (seen 2026-10-30)\n- robots.txt: \u003chttps://arcmira.com/robots.txt\u003e (seen 2026-10-30)\n- MCP server repository (tools.ts, CHANGELOG, CI, LICENSE): \u003chttps://github.com/arcmira/mcp\u003e (seen 2026-10-30)\n- GitHub organisation and repositories: \u003chttps://api.github.com/orgs/arcmira/repos\u003e (seen 2026-10-30)\n- MCP repository issues and CI runs: \u003chttps://api.github.com/repos/arcmira/mcp/issues?state=all\u003e (seen 2026-10-30)\n- official MCP registry: \u003chttps://registry.modelcontextprotocol.io/v0/servers?search=arcmira\u003e (seen 2026-10-30)\n- npm, arcmira: \u003chttps://registry.npmjs.org/arcmira\u003e (seen 2026-10-30)\n- RDAP for arcmira.com: \u003chttps://rdap.verisign.com/com/v1/domain/arcmira.com\u003e (seen 2026-10-30)\n\n## Score history\n\nEvery move of a score since the listing was graded, newest first, with its cause.

The vendor's docs changelog dates the first public API (v1.0.0) to April 2026 without a day, so the product is older than this date shows.

LinkedIn: https://www.linkedin.com/in/zealcaiden/. X: https://x.com/zealcaiden. GitHub: https://github.com/zealous1\n- Note: arcmira.com has no about or team page (/about answers 403 and the static sitemap lists none), the terms and privacy policy name only arcmira, inc. and a contact address, and no blog or press page was found. the one person named is zeal caiden, whose role comes from arcmira's own entity page (https://arcmira.com/person/zeal-caiden, 'founder of arcmira') and from the github profile of zealous1 ('ceo @ arcmira'), the account behind the organisation's repositories, the npm package and the registry entry. no linkedin or x profile for him is linked from arcmira.com, so none is recorded. the company's x and linkedin links come from the schema.org markup on arcmira.com's pages and weren't opened. the roster may be incomplete; the privacy policy calls arcmira 'a small team'. investors were looked for on arcmira.com (llms.txt, pricing, labs, contact sales, terms, privacy, the docs changelog and the sitemap, which has no blog or press section), in the github organisation profile (no public readme) and in web searches for arcmira funding, the founder and the legal entity, which returned third-party directory pages and nothing on a round. third-party directory claims about the founder's earlier companies and a founding year weren't used. his linkedin and x links are the ones his github profile's linked social accounts give (https://api.github.com/users/zealous1/social_accounts, read 30 october 2026); the founder found the same linkedin address independently.\n- Arcmira, Inc.: LinkedIn https://www.linkedin.com/company/arcmira X https://x.com/arcmiraAI GitHub https://github.com/arcmira\n\n### Getting support\n\n- Support email: hi@arcmira.com\n- Help: https://arcmira.com/docs/feedback\n- Help: https://arcmira.com/docs\n- Community (GitHub issues, arcmira/mcp): https://github.com/arcmira/mcp/issues\n- Sources: https://arcmira.com/person/zeal-caiden, https://github.com/zealous1, https://arcmira.com/terms, https://arcmira.com/privacy, https://arcmira.com/llms.txt, https://arcmira.com/docs/feedback.md, https://arcmira.com/contact/sales, https://arcmira.com/labs, https://arcmira.com/pricing, https://arcmira.com/sitemaps/static-0.xml, https://api.github.com/orgs/arcmira, https://registry.npmjs.org/arcmira, https://registry.modelcontextprotocol.io/v0/servers?search=arcmira, https://api.github.com/users/zealous1/social_accounts\n\n## Live (updated 2026-10-30 17:21 UTC)\n\n- Right now: up, HTTP 401, 128 ms, checked 2026-10-30 17:21 UTC (mcp-initialize on `https://mcp.arcmira.com/mcp`, asks for auth)\n- Uptime 24h 100.0% (18 probes) · 30 days 100.0% (18 probes) · p50 281 ms · p95 465 ms\n- Always current: https://www.anchorterminal.com/api/v1/live/arcmira.json\n\n## Probe metrics\n\nNot measured yet.

Call `arcmira_describe` once per session and write one program per question for `arcmira_execute_read`; return only the fields the answer needs, since output is cut at 12,000 characters and 3,000 per string.\n2. Resolve names with `arcmira.resolve` (free) before any `about`, `by`, `entity_ids` or `channel` filter; a name in a filter fails with `id_required`. Plain keyword search needs no resolver call.\n3. Check `arcmira.status()` or GET /v1/me for the plan, scopes and `usage.credits.available` before metered reads; on Free, media newer than 30 days and pages past the first fail with `freshness_requires_paid` and `pagination_gated`.\n4. A Premium read of an untranscribed video starts a transcription that uses credits (300 per started 15 minutes) and may return `pending`; read the same video again later, which is never charged twice, and send `retry: true` only when the user asks.\n5. Over HTTP send `Authorization: Bearer arc_sk_...`, an `Idempotency-Key` on every POST and PATCH, honour `Retry-After` on 429, and switch on `error.code`, following `unlock.url` on 402 and 403 rather than re-authenticating.\n6. Use `arcmira_execute_write` only after listing the user's monitors; it creates, follows and pauses but never deletes, and a connection made before server 0.9.0 answers `insufficient_scope` until reconnected.\n\n## Connect\n\nInstall:\n\n```bash\nnpm install arcmira\n```\n\nFirst request:\n\n```bash\ncurl 'https://api.arcmira.com/v1/search?q=corporate%20cards\u0026limit=5' -H \"Authorization: Bearer $ARCMIRA_API_KEY\"\n```\n\nClaude Code:\n\n```bash\nclaude mcp add --transport http --scope user arcmira https://mcp.arcmira.com/mcp\n```\n\nMCP client configuration:\n\n```json\n{\n \"mcpServers\": {\n \"arcmira\": {\n \"url\": \"https://mcp.arcmira.com/mcp\"\n }\n }\n}\n```\n\nThrough letme: https://letme.dev/arcmira (letme picks it for audio.transcribe, the top-graded tool for the job). letme answers with the pick and how to call it direct.

Only `arcmira_describe` is readOnlyHint true; `arcmira_execute_read` is not read-only because a Premium read can start a transcription that uses credits, and `arcmira_execute_write` is destructiveHint true because it changes existing monitors (source: \u003chttps://arcmira.com/docs/mcp-server.md\u003e)\n- The program never holds the key. It runs in a Cloudflare Dynamic Worker isolate whose only network is a proxy that adds the caller's credential, and the server is a Cloudflare Worker at mcp.arcmira.com (source: \u003chttps://github.com/arcmira/mcp/blob/master/wrangler.jsonc\u003e)\n- A public OpenAPI 3.1 file with 31 paths, 35 operations and 75 schemas at https://api.arcmira.com/v1/openapi.json, every POST and PATCH taking an `Idempotency-Key` that replays with `Idempotency-Replayed: true`, and an error catalogue of about 60 codes with `unlock.url`, `details.limit` and `doc_url` on each (source: \u003chttps://arcmira.com/docs/errors.md\u003e)\n- Rate limits are 60 requests a minute per key on Free, 240 on paid plans and 600 on Enterprise, with `RateLimit-Limit`, `RateLimit-Remaining` and `RateLimit-Reset` on every authenticated response and `Retry-After` on 429 (source: \u003chttps://arcmira.com/docs/usage-and-billing.md\u003e)\n- Monitor webhooks are signed with HMAC-SHA256 over `{timestamp}.{raw body}` in `X-Arcmira-Signature`, with a 300-second timestamp window, a rotate endpoint and a 24-hour overlap signed as `X-Arcmira-Signature-Previous`; webhooks need a paid plan (source: \u003chttps://arcmira.com/docs/monitors.md\u003e)\n- Since server 0.8.2 every tool call is logged to the vendor's product analytics with the account, host, duration, the first 4,000 characters of the program, the agent's `intent` and the outcome, credentials and email addresses redacted, results never recorded, no opt-out (source: \u003chttps://arcmira.com/docs/mcp-server.md#what-we-log\u003e)\n- Between 5 and 8 October 2026 the v1 API retired `POST /v1/trackers` (410 `tracker_create_retired`) and six tracker delivery fields for the team account model; the changelog lists seven rows that can break a client, dated the day the change finished (source: \u003chttps://arcmira.com/docs/changelog.md\u003e)\n- No status page, SLA or security.txt was found on arcmira.com, api.arcmira.com or mcp.arcmira.com; the terms (effective 13 October 2026) name Arcmira, Inc. in San Francisco and disclaim uninterrupted service (source: \u003chttps://arcmira.com/terms\u003e)\n- Official MCP registry entry io.github.arcmira/arcmira with 30 versions from 0.3.0 on 4 September 2026 to 0.10.7 on 12 October 2026; the repository was created on 12 October with earlier history and CI passing on master on 30 October (source: \u003chttps://registry.modelcontextprotocol.io/v0/servers?search=arcmira\u003e)\n\n- #11 of 19 in Best web search APIs for AI agents: https://www.anchorterminal.com/best/search/index.md\n- All 182 search comparisons: https://www.anchorterminal.com/compare/search/index.md\n\n## Compare\n\n- [Web Search Tool on Amazon Bedrock AgentCore vs Arcmira](https://www.anchorterminal.com/compare/agentcore-web-search-vs-arcmira.md): BB 74.3 vs B 64.2\n- [Arcmira vs Brave Search API + MCP](https://www.anchorterminal.com/compare/arcmira-vs-brave-search-mcp.md): B 64.2 vs B 68\n- [Arcmira vs Cloudflare Web Search API](https://www.anchorterminal.com/compare/arcmira-vs-cloudflare-web-search.md): B 64.2 vs C 61.9\n- [Arcmira vs DeepSeek Search and Fetch API](https://www.anchorterminal.com/compare/arcmira-vs-deepseek-search-api.md): B 64.2 vs D 53.2\n- [Arcmira vs Firecrawl MCP](https://www.anchorterminal.com/compare/arcmira-vs-firecrawl-mcp.md): B 64.2 vs A 78\n- [Arcmira vs Kagi Search API](https://www.anchorterminal.com/compare/arcmira-vs-kagi-search.md): B 64.2 vs D 48.7\n- [Arcmira vs SearchAPI.io](https://www.anchorterminal.com/compare/arcmira-vs-searchapi-io.md): B 64.2 vs D 51.4\n- [Arcmira vs SerpApi](https://www.anchorterminal.com/compare/arcmira-vs-serpapi.md): B 64.2 vs B 62.5\n- [Arcmira vs Serper](https://www.anchorterminal.com/compare/arcmira-vs-serper.md): B 64.2 vs F 24.2\n- [Arcmira vs SerpKite](https://www.anchorterminal.com/compare/arcmira-vs-serpkite.md): B 64.2 vs B 64.8\n- [Arcmira vs Exa API + MCP](https://www.anchorterminal.com/compare/arcmira-vs-exa-mcp.md): B 64.2 vs B 66.1\n- [Arcmira vs Grep AI](https://www.anchorterminal.com/compare/arcmira-vs-grep-ai.md): B 64.2 vs B 64.6\n- [Arcmira vs Linkup](https://www.anchorterminal.com/compare/arcmira-vs-linkup.md): B 64.2 vs B 68.9\n- [Arcmira vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/arcmira-vs-parallel-search-api.md): B 64.2 vs BB 75.1\n- [Arcmira vs Tavily API + MCP](https://www.anchorterminal.com/compare/arcmira-vs-tavily-mcp.md): B 64.2 vs BB 77\n- [Arcmira vs TinyFish Search](https://www.anchorterminal.com/compare/arcmira-vs-tinyfish-search.md): B 64.2 vs B 63.2\n- [Arcmira vs Valyu](https://www.anchorterminal.com/compare/arcmira-vs-valyu.md): B 64.2 vs B 64.6\n- [Arcmira vs You.com APIs](https://www.anchorterminal.com/compare/arcmira-vs-you-com-api.md): B 64.2 vs BB 75.9\n\n## Verify this listing\n\nFor the vendor.
