## Which one, for what

### Axiom MCP Server (B)

Good for: Agents that investigate logs, traces and metrics with APL and need a budget cap, and agents that must bootstrap their own observability without a person.

Ahead on:
- Reliability, 72 against 50
- Schema & documentation, 62 against 46
- Agent ergonomics, 63 against 55
- Security & auth, 72 against 60
- Payments & pricing, 60 against 40
- Maintenance & community, 83 against 71

Also in its favour:
- Free to start without a card

Watch for: The server is closed source and tool input schemas are only visible through an authenticated session

### Better Stack (C)

Good for: An agent that investigates incidents, queries logs and metrics with SQL, manages monitors and posts status page updates for a team already on Better Stack, with the Claude plugin as the shortest route.

Watch for: No rate limit numbers in the API docs, and the only 429 guidance is to wait before retrying


## Why the edge

### Reliability: Axiom MCP Server +22

- Axiom MCP Server (72): Scored as a hosted MCP server. status.axiom.co is an incident.io page with six US and six EU components (API, ingest, querying, alerting, endpoints, app) and uptime per component for August to November 2026, with no MCP component (20). feed.rss holds nine incidents in the 90 days to 3 November 2026, among them elevated query errors in the US from 18:05 to 19:15 UTC on 14 October with missed monitor runs, a metrics ingestion and query disruption on 15 October, elevated query errors after a deployment on 21 October, metrics query error rates on 25 October, query errors and monitor delays on 27 October, metrics ingest on 30 October, EU monitor alerting degraded on 7 October, and console authentication through GitHub degraded on 12 August. US querying shows 99.90 per cent uptime. One incident over an hour on the query path and several shorter ones, so one major (10). Rate limits are published as headers (X-RateLimit-Scope, -Limit, -Remaining, -Reset) and plan limits on the limits page, but the per-minute numbers aren't printed (12). 429 with a message and reset headers, query cost caps that answer 429 with the reset time, and provisioning 429 with backoff guidance; no idempotency keys for the write tools (10). A published SLA of 99.9 per cent monthly uptime for Axiom Cloud with 10 and 25 per cent credits (10). Not marked beta; registry version 1.0.0 (10). 20 + 10 + 12 + 10 + 10 + 10 = 72.
- Better Stack (50): Read with the hosted lines and scored on the remote MCP server at mcp.betterstack.com, which fronts the same service as the Incidents and Telemetry APIs. status.betterstack.com runs on Better Stack's own status page product with three components and a 90-day history (20). Between 5 August and 3 November 2026 it records delayed Telemetry data processing in the Europe region from 3 to 6 September in entries of 6 hours 19 minutes, 10 hours 10 minutes, 19 hours 13 minutes, 21 hours 45 minutes and 1 day, a 9-minute Telemetry degradation on 20 August, 39 minutes of wrong downtime notifications on 21 October and 8 minutes of dashboard unavailability on 2 November, every one labelled degraded, plus two migrations labelled maintenance (11 hours 13 minutes on 9 August and 17 hours). About four days of delayed log processing in one region is more than trivial and less than an outage of the API, so between minor-only and one major (15). No rate limit numbers were found in the API or MCP docs (0). The Usage API documents a 429 with the instruction to wait before retrying, with no Retry-After, no backoff guidance and no idempotency keys. `Upsert catalog records` is documented as not creating duplicates when repeated (5 of 15). No SLA. The terms supply the service as is, and the enterprise page lists SLA reporting as a feature (0). The MCP server was announced on 15 September 2025 and carries no beta label (10). 20 + 15 + 0 + 5 + 0 + 10 = 50.

### Payments & pricing: Axiom MCP Server +20

- Axiom MCP Server (60): No x402, MPP or L402 (0). The pricing page states the platform fee, the free allowances, add-on prices and that usage carries volume discounts, with a calculator rather than a printed per-unit rate (20). The Personal plan is free with no card (20). `POST /v2/orgs/provision` needs no authentication and returns a working token, so an agent can start without a person, though a person must claim the organisation within 24 hours for it to persist (20). 0 + 20 + 20 + 20 = 60.
- Better Stack (40): Read with the hosted rubric. No x402, MPP or L402 (0). Per-unit prices are public without login, by GB and region for telemetry, per responder, per status page and per phone number (20). The Free plan has 10 monitors, a status page and 3 GB of logs, the signup page says Sign up for free and names no card, and we did not run the signup flow (20). A person signs up in a browser and mints a token or completes OAuth there (0). 0 + 20 + 20 + 0 = 40.

### Schema & documentation: Axiom MCP Server +16

- Axiom MCP Server (62): The server is closed source (axiomhq/mcp isn't public) and tools/list needs a session, so the input schemas couldn't be read; partial credit for a contract that exists (10). llms.txt on axiom.co and a Markdown twin of every docs page (10). The tools reference gives each tool a purpose, an example request and a Read or Write label, says to use `queryMetrics` for metrics datasets instead of `queryDataset`, and the 29 October 2026 changelog adds session instructions on finding dataset and field names first (15). No parameters, types or enums are published for the tools (4). An example per tool, the REST docs' error shapes and the 429 bodies; no MCP error list (8). A dated changelog with MCP entries and a protocol version stated (2026-07-28 alongside the session transport), and a registry version (15). 10 + 10 + 15 + 4 + 8 + 15 = 62.
- Better Stack (46): The server is closed and tools/list needs sign-in, so the tool schemas were not read, and no OpenAPI file was found for the REST APIs in the docs, the GitHub organisation or a search. Partial credit for a typed contract that exists but isn't public (10 of 25). No llms.txt on betterstack.com or its docs, and no Markdown twins (0). The MCP docs page gives one line per tool and says when some apply, such as Reopen incident within 24 hours and the instruction tools to call before Execute query. The REST reference pages describe each endpoint in a sentence (12 of 20). Inputs are typed only in the REST docs, with parameter tables, monitor types and status values listed in prose, and no schema to validate against (7 of 15). Every REST page carries a curl example and a 200 body; Create monitor documents a 422 with errors keyed by field, the Usage API a 401 and a 429, and no error code list exists (9 of 15). The APIs are versioned v2 in the path. The changelog is a product feed of 19 entries since March 2025 with the MCP server among them, with no API changelog and no deprecation notes (8 of 15). 10 + 0 + 12 + 7 + 9 + 8 = 46.

### Security & auth: Axiom MCP Server +12

- Axiom MCP Server (72): Browser OAuth creates a session the agent uses as the signed-in user, listed and revocable under Settings > Profile, and the docs say agents never see tokens; the header route uses a personal access token with full account rights, and the organisation id, not a secret, may go in the URL (26). Query cost limits on roles cap what an OAuth session can spend, scoped API tokens with expiry exist for the REST API, but the MCP server runs with the user's whole role and lists delete tools with no confirmation, and the AI agents page's read-only description contradicts the tools reference (12). Log, trace and event content is untrusted text and no injection guidance was found (2). An audit log on every organisation for 30 days, full history as an add-on, and session listing (12). ISO 27001, SOC 2 Type II, a security.txt on app.axiom.co, a bug bounty policy at axiom.co/security and annual penetration tests (20). 26 + 12 + 2 + 12 + 20 = 72.
- Better Stack (60): OAuth sign-in with a Full access level chosen at consent, or API tokens that are global or scoped to one team with Read & write or read access, minted and deleted in Settings. No scopes finer than read and write, no expiry and no PKCE or dynamic registration documented (24 of 30). Read-level tokens and consent, the two header allowlists, and the rule that comments can only be changed by their author or a token. No confirmation step before Remove monitor, Remove dashboard, Resolve incident or Remove team member (12 of 20). Logs, spans, errors and replays are untrusted text returned to the model, and no injection guidance was found in the MCP docs (2 of 15). Audit logs record every API token request with actor_type api_token and the token's name, never its value, and can be streamed to a Telemetry source or any URL, though the pricing page lists audit logs as a $250 a month add-on (12 of 15). SOC 2 Type 2 with the report on request, third-party penetration tests, security@betterstack.com for disclosures. No security.txt (404), no bug bounty and no disclosure policy page (10 of 20). 24 + 12 + 2 + 12 + 10 = 60.

### Maintenance & community: Axiom MCP Server +12

- Axiom MCP Server (83): Read as a closed service. Changelog entry of 29 October 2026 covering the MCP server (30). Dated entries on 7 August, 23 September and 16, 21, 22, 28 and 29 October 2026 (20). A Discord community linked from the company page, support@axiom.co in the docs and email support on paid plans; no public issue tracker for the hosted server (12 of 15). co.axiom/mcp in the official registry under a DNS-verified namespace since 30 September 2025, though the entry still points at the SSE URL and version 1.0.0 (15). No package to assess for a hosted server; Axiom keeps SDKs in eight languages for the API (6). 30 + 20 + 12 + 15 + 6 = 83.
- Better Stack (71): Read as a closed service. The Claude plugin reached 1.3.12 on 2 November 2026 and the changelog's newest entry is 29 October 2026 (30). Changelog entries on 10 August, 9 September, 1 October, 15 October and 29 October 2026 (20). Public changelog, hello@betterstack.com with a stated reply within a few hours, and a community site. GitHub issues on the plugin repositories were not read (10 of 15). The MCP server is not in the official MCP registry under a verified namespace, the only entries matching the name being third-party scrapers, and there is no official API SDK. The Claude, Cursor, Codex and Antigravity plugins and two Terraform providers are current (5 of 15). The Claude plugin repository is MIT with 12 commit days since June 2026, and we didn't read its CI (6 of 10). 30 + 20 + 10 + 5 + 6 = 71.

### Agent ergonomics: Axiom MCP Server +8

- Axiom MCP Server (63): 31 tools in the reference, 28 without service map, so the 11-to-30 band with no toolset switch (15). APL queries take their own limits and time ranges, and the REST API documents timestamp pagination; nothing documents page sizes for the list tools (15). 429 bodies state the limit and reset, the REST docs describe error shapes, and a `sendFeedback` tool reports unclear descriptions to Axiom (12). Reads and writes are labelled in the docs, but delete tools have no confirmation step, no idempotency keys exist for writes, and annotations weren't confirmed (8). One-command setup for 16 clients with OAuth, a setup prompt for agents, and official SDKs in eight languages for the API behind it (13). 15 + 15 + 12 + 8 + 13 = 63.
- Better Stack (55): 148 tools are named on the docs page, more than 30 (5). X-MCP-Tools-Only and X-MCP-Tools-Except narrow the list to a subset or a read-only set, documented for that purpose, and the server has no default toolset (add 10, so 15). REST lists take page and per_page up to 250 with first, last, prev and next links, and filters by url, pronounceable_name and team_name. Plan query windows splits a long telemetry query into windows, and Execute query takes SQL with its own LIMIT. No field selection (16 of 20). 422 bodies name the field that failed and 401 gives a message, but no error code list exists and MCP errors are not documented (10 of 20). No idempotency keys. `Upsert catalog records` avoids duplicates, Reopen incident is limited to 24 hours, and the annotations on the tools couldn't be read (6 of 20). Get workspace style defaults are not described. Two Terraform providers and logging clients exist, but no official API SDK in any language, and the Claude plugin's 16 skills carry the query recipes (8 of 15). 15 + 16 + 10 + 6 + 8 = 55.

## Verdicts

**Axiom MCP Server.** An agent can start without a person, provisioning a temporary organisation with one unauthenticated call, and then query with OAuth sessions capped by dollar cost limits under a 99.9 per cent SLA. Tool schemas aren't public, the server is closed source, and the docs call it read-only while listing delete tools.

**Better Stack.** One remote MCP server reaches incidents, on-call, monitors, status pages, logs, metrics, traces and errors with OAuth or a team-scoped token, and two headers cut its 148 tools down. Tool schemas and rate limits aren't published, there is no SLA, and audit logs of token use are a paid add-on.

## Before you call either

### Axiom MCP Server

1. With no organisation, call `POST https://api.axiom.co/v2/orgs/provision` once, store the returned token and surface the `claimUrl` to the person; both are shown once and the organisation is deleted after 24 hours unclaimed
2. Call `listDatasets` and `getDatasetFields` before `queryDataset`; metrics datasets take `queryMetrics` with MPL, not APL
3. Treat a 429 as a rate limit or a query-cost cap; read `X-RateLimit-Reset` or the limit message for when the window resets, and don't resend sooner
4. Prefer OAuth; if a token header is the only option, expect the PAT to carry the person's full rights and ask them to set a query cost limit on their role first
5. `deleteDashboard`, `deleteMonitor` and `deleteNotifier` are live writes with no confirmation step; list first and confirm with the person before deleting

### Better Stack

1. Connect with `claude mcp add betterstack --transport http https://mcp.betterstack.com` and sign in, or send a team-based API token as `Authorization: Bearer`; pick Read access unless the task writes
2. Send `X-MCP-Tools-Only: monitors,monitor,incidents` or a similar list to keep the 148-tool list out of context, and `X-MCP-Tools-Except: remove_dashboard,remove_chart` to block deletes
3. Call `Get query instructions` or `Plan query windows` before `Execute query`, since long time ranges are split into windows and nothing documents a result size limit
4. No rate limit is published. Back off on a 429 and don't retry writes blindly, because there are no idempotency keys; `Upsert catalog records` is the one write documented as safe to repeat
5. Reopening an incident only works within 24 hours of its resolution, and a comment can only be edited or removed by its author or an API token
