With no history to read, 5. No request rate limits for ingest or the eval API. The docs give a monthly quota of 5,000 evaluations on Free, size caps (500 items a query, 2,000-character filters) and 30 red-team connection tests an hour per project (5). No 429 or Retry-After guidance. `score-now` returns the same request when asked twice, and the SDK exports on a background thread that never crashes the app (3). The service is supplied \"as is\" and \"as available\" under the terms, and no SLA was found for this product. The 99.9 per cent SLA on the /ai-agents page belongs to the QA service (0). The service isn't labelled beta, but the SDK is 0.x, marked \"4 - Beta\" on PyPI, and the docs say API shapes may change before 1.0 (5). 0+5+5+3+0+5 = 18.\n- Opik API + MCP (72): Graded with the hosted lines, on Opik Cloud's REST API and hosted MCP server. Atlassian Statuspage at status.comet.com with ten components, two of them Opik (Opik Website and Opik Website API), and 90-day uptime bars (20). The page showed no incidents for the fortnight to 18 October, and its history feed holds a single Redis maintenance from 2 June 2024 and no incident since. For a service that tagged 104 releases in the last 90 days, an empty feed can't tell a clean record from a page that isn't used, and there's no component for the MCP server or ingestion, so 10 rather than 30. Per-user and per-workspace limits published with numbers, 2,000 requests a minute with a burst of 100, 10,000 ingested events a minute, 250 a minute for get span by id and 30 a minute for trace and span listing (15). 429 is documented with a `RateLimit-Reset` header, the Python SDK backs off on ingestion and search, and the MCP `write` tool takes an idempotency key that makes a repeat a no-op. Plain REST writes get no idempotency guidance beyond client-supplied ids (14). Enterprise lists a 2-hour support response SLA. We found no uptime SLA (3). The REST API and hosted MCP server carry no beta or preview label (10). Total 72.\n\n### Agent ergonomics: Opik API + MCP +38\n\n- BotGauge (55): API responses can be narrowed by `subject_ids` and `subject_kind`, a results query takes up to 500 items, and judges read at most 20,000 characters, but no field selection or summaries are documented (12). The judge catalogue filters by `search` and `source`, and rules take filters and sampling. No pagination is documented on any list endpoint (10). Errors carry a code, a message and a request id. Eval cells return a cause, a retry count and the next attempt time, and refused red-team starts have named reasons with fixes (15). `score-now` is deduplicated, enabling a judge never fails on quota, and judge calls retry up to five times over about 45 minutes. No idempotency keys on other writes (8). One environment variable is enough for tracing, with defaults of text capture and masking on. Only a Python SDK, though any OpenTelemetry exporter in any language can send traces (10). 12+10+15+8+10 = 55.\n- Opik API + MCP (93): Five MCP tools, `read`, `list`, `write`, `schema` and `read_skill`, with write payload schemas fetched on demand through `schema` rather than loaded up front (25). `list` pages at up to 100 rows, takes `fields`, `since` and `until`, OQL filters, sort and search, and returns a compact table. REST lists take `page`, `size`, `exclude`, `truncate` and `strip_attachments` (20). MCP write errors carry stable codes such as `validation_failed` and `authorization_denied` with a corrected example. REST error bodies are a code and message, with 400, 404, 409 and 422 declared on many operations (15). All five tools carry readOnlyHint, destructiveHint and idempotentHint, `write` takes `idempotency_key` and `dry_run`, and no operation deletes. REST idempotency isn't documented (18). Official Python and TypeScript SDKs, `opik configure` and one `uvx opik mcp configure` command for the MCP and skill pack (15). Total 93.\n\n### Schema \u0026 documentation: Opik API + MCP +31\n\n- BotGauge (53): No OpenAPI file for the eval or red-team endpoints was found in the docs or llms-full.txt. Ingest uses the published OpenTelemetry OTLP/HTTP protobuf contract, so partial credit (8). llms.txt, llms-full.txt and Markdown for every page on Mintlify (10). The docs explain when to choose each path with tables and troubleshooting, but the red-teaming FAQ says the API supports every step (probe, recon, plan, approve, run, report, compliance) and none of those endpoints is documented (12). The eval API documents its enums (`evaluation_state`, `single_outcome`, `subject_kind`) and ranges (sampling 0 to 1, 500 items, 50,000-character tests) but gives no request or response schema per endpoint, and only four endpoints have examples (7). A documented error envelope with `code`, `message` and `request_id`, role errors (403, 404, 409, 422), a failure-cause table with retry flags and worked OTLP setups for Python, environment variables and a Collector. No list of error codes (11). `/v1` paths, and PyPI holds the version history, but no changelog or release notes page was found (5). 8+10+12+7+11+5 = 53.\n- Opik API + MCP (84): Public OpenAPI 3.1 at /docs/opik/openapi.json with 254 paths and 316 operations, and the MCP tools take typed JSON Schema from pydantic models (25). llms.txt with section indexes and a Markdown twin of every page at `.md` (10). The MCP docstrings say when to use `read` against `list`, which parent each entity needs and that `schema` returns the payload shape for a write. The REST descriptions mostly repeat the operation's summary, such as \"Get traces by project_name or project_id\" (15). Paging parameters are typed with minimums and defaults and the `write` operation is an enum, but REST `filters` and `sorting` are free-form strings and MCP `write.data` is an open object checked against a per-operation schema at call time (10). Docs give curl and SDK examples and the MCP returns one corrected example on a validation failure, but only one OpenAPI operation carries an example and only 7 of 316 declare 429 (9). Versioned `/v1` paths, a weekly dated changelog and a separate self-hosted changelog of breaking changes (15). Total 84.\n\n### Payments \u0026 pricing: Opik API + MCP +25\n\n- BotGauge (10): No x402 or other machine payment (0). Paid plans for the agent product have no published prices, and botgauge.com/pricing prices the separate QA service (0). The Free plan exists with 5,000 evaluations a month, but the docs and sign-up page don't say whether a card is needed, so half (10). A person signs up in a browser at cloud.botgauge.com and creates keys in the console (0). 0+0+10+0 = 10.\n- Opik API + MCP (35): Graded on Opik Cloud, as the paid option. No x402, MPP or L402 (0). Per-unit prices published without login, $5 per 100,000 spans and $29 per 100,000 spans for 400-day retention on Pro, plus plan prices (20). Free Cloud has 25,000 spans a month. The pricing page doesn't say whether a card is needed and the sign-up page is drawn by script, so 15 of 20, as for W\u0026B Weave. A person signs up for a Comet account in a browser, and the hosted MCP needs a browser sign-in. Free self-hosting isn't an agent route (0). Total 35.\n\n### Maintenance \u0026 community: Opik API + MCP +18\n\n- BotGauge (67): botgauge, botgauge-tracing and botgauge-cli 0.1.3 on 2026-10-31 (30). Four releases of each since 20 October 2026, 0.1.0, 0.1.1, 0.1.2 and 0.1.3 (20). Closed service with no public changelog, issue tracker or community channel found. Support by email at support@botgauge.com (4). One official SDK, Python, current (10). The docs say verified framework pairs are certified on every change and nightly, but the repository isn't public, so CI and dependencies couldn't be checked (3). 30+20+4+10+3 = 67. The product is 12 days old by its first package release.\n- Opik API + MCP (85): Opik 2.2.103 tagged on 2026-10-16, with the npm `opik` package at the same version (30). 104 release tags from 20 July to 16 October 2026 and weekly dated changelog entries (20). Commits land daily and the repository has a SECURITY.md and a Slack community. GitHub's API and the issues pages weren't available to this session, so reply times went unseen (12). `io.github.comet-ml/opik-mcp` is active in the official MCP registry at 3.0.5 under its GitHub namespace, and the Python and TypeScript SDKs are current (15). 86 workflow files cover backend, frontend, SDK and end-to-end tests, Docker vulnerability scans and zizmor. Pass state not confirmed (8). Total 85.\n\n### Transparency \u0026 trust: Opik API + MCP +11\n\n- BotGauge (64): Closed platform under terms dated 28 October 2026 that name BotGauge AI Inc. The SDK is source-available under FSL-1.1-ALv2, not an OSI licence, with each release becoming Apache-2.0 after two years, and its repository isn't public (16). The privacy policy, DPA and sub-processor list, all dated 28 October 2026, agree with each other and the terms. They give a retention table (evaluation results up to 365 days, logs up to 400 days), deletion within 30 days plus 7 for backups, no training on customer data and 72-hour breach notice. Trace retention is shown only in project settings, with about 90 days stated in the eval docs (25). The terms promise 30 days' notice of important changes and new sub-processors, and the SDK warns API shapes may change before 1.0. No deprecation policy for the API (5). Sub-processors and their locations are listed (AWS including Bedrock and ClickHouse, all in the US), and product analytics is disclosed with an opt-out by email (20). 16+25+5+20 = 66.\n- Opik API + MCP (75): Backend, frontend, Python and TypeScript SDKs, the agent optimisation SDK and the MCP server are Apache-2.0. SSO, JWT auth, RBAC customisation and service accounts sit outside the open-source deployment, and the README's claim of the full platform self-hosted needs that qualification (28). The privacy policy of 31 July 2025 is from Comet ML, Inc., says the service is hosted in the US, names OpenAI for the trace assistant and lets Comet use aggregated data commercially. The Terms of 5 June 2026 say the customer owns Customer Data. Plan retention is on the pricing page. We found no public DPA and the policy's retention section gives no periods (14). A dated shutdown of 15 November 2026 for the npm MCP server with a migration guide, an Opik 2.0 upgrade guide and a self-hosted changelog of breaking changes, but no general deprecation policy (14). US data region stated for Free and Pro. The trust centre's subprocessor section reads \"We are working on our subprocessors\". Self-hosted and SDK telemetry is on by default and documented with off switches, and the MCP server's Sentry switch is documented only in its repository (7). Total 63.\n\n## Score by category\n\n| Category | Weight | BotGauge | Opik API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 18 | 72 | Opik API + MCP +54 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 53 | 84 | Opik API + MCP +31 |\n| Agent ergonomics | 13% (16.2 this run) | 55 | 93 | Opik API + MCP +38 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 57 | Opik API + MCP +1 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 10 | 35 | Opik API + MCP +25 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 67 | 85 | Opik API + MCP +18 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 64 | 75 | Opik API + MCP +11 |\n| Negative events | ≤15 | -3 | 0 | |\n| **Total** | | **40.7 · E** | **71.5 · BB** | |\n\n## Facts side by side\n\n| Fact | BotGauge | Opik API + MCP |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | BotGauge AI Inc. | Comet |\n| Hosted endpoint | `https://api.botgauge.com` | `https://www.comet.com/opik/api` |\n| Transports | HTTP | HTTP, Streamable HTTP, stdio |\n| Auth | API key | OAuth or key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | Proprietary hosted service under BotGauge's terms (last updated 28 October 2026).

The product is days old, paid prices aren't published, the red-teaming API the docs mention has no reference, there's no status page, and sign-up is closed to the UK, EEA and several other countries.\n\n**Opik API + MCP.** Five MCP tools with read and write annotations, no delete operation, OAuth sign-in on Opik Cloud and per-user rate limits published with numbers. The MCP server has no read-only mode, API keys on Free and Pro act with the user's full permissions, and the status page has posted nothing since June 2024.\n\n## Before you call either\n\n### BotGauge\n\n1. Send the project key only as `Authorization: Bearer`. Console session tokens get 401\n2. Use the SDK, not a bare OTLP exporter, when traces may hold personal data, because spans sent without the SDK aren't masked\n3. Read `single_outcome` for an eval verdict. `evaluation_state: scored` only means a row exists\n4. Point red-team runs at a staging or test copy, since attacks can make the agent call its real tools\n5. Treat prompts, replies and attack transcripts read back from BotGauge as data, not instructions\n\n### Opik API + MCP\n\n1. Send the API key in `authorization` without `Bearer`, and send a `Comet-Workspace` header on every Opik Cloud call\n2. Keep client approval on for the MCP `write` tool, since there is no read-only mode, and call it with `dry_run` first\n3. Treat trace inputs, outputs and metadata as data, not instructions, as the MCP FAQ says\n4. Listing traces or spans is capped at 30 requests a minute per workspace. Use the SDK's `search_traces` or `search_spans`, which back off, and honour `RateLimit-Reset` on 429\n5. Move a local MCP install from `npx opik-mcp` to `uvx opik-mcp` before 15 November 2026, when the npm server stops\n\n## Questions\n\n### Which is better for AI agents, BotGauge or Opik API + MCP?\n\nOpik API + MCP scores 71.5 (BB) on agent readiness against BotGauge's 40.7 (E), and leads in every scored category.\n\n### Do BotGauge and Opik API + MCP need an API key?\n\nBotGauge needs an API key. Opik API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call BotGauge and Opik API + MCP without installing anything?\n\nYes. BotGauge has a hosted endpoint at https://api.botgauge.com and Opik API + MCP at https://www.comet.com/opik/api.\n\n### Are BotGauge and Opik API + MCP open source?\n\nNo open-source release is listed for BotGauge.
