DatoCMS is Good to agents.

Discry independently scored how well an AI agent can discover and understand the DatoCMS API from what’s public — not whether it’s usable. Below: every signal we checked, what’s costing the score, and what to change.

SCORED UNDER RUBRIC 1.2 · A full re-launch under Discry Score 2.5 — a new behavioral instrument, not comparable to these scores — is in progress.

What we found

  • An agent reading the docs gets clean, purpose-built markdown for free: every page exposes a .md variant plus 'View as Markdown', 'Copy Markdown link', and 'Open in ChatGPT/Claude' buttons — DatoCMS has clearly engineered the docs for LLM consumption, not just human browsing.
  • Error recovery is best-in-class: the CMA errors page documents ~80 distinct error codes, each with an explicit 'To resolve this...' step, transient-retry flagging, and a doc_url returned in the live error body — an agent can self-correct from a 4xx without ever leaving the response payload.
  • The biggest discovery gap is the missing llms.txt / llms-full.txt (both 404). An agent that relies on the llms.txt convention to find an entry point gets nothing, despite the underlying docs being unusually agent-ready — a few-hours fix that would meaningfully lift the Discovery score.
  • Agent-readiness is a deliberate product strategy here: there's a dedicated datocms/agent-skills repo teaching Claude/Codex/Cursor to work with the API, an official remote MCP server at mcp.datocms.com (OAuth), AGENTS.md in the plugins repo, and a write-safety header (X-Abort-If-Destructive-Request) built specifically for MCP read-only mode.
  • Discovery is the weak dimension (62/C) almost entirely on convention-file absences (llms.txt, .well-known/mcp.json) and a marketing sitemap that omits /docs pages — not on substance. The machine-readable spec exists (JSON Hyperschema at a stable, documented URL), so the API itself is well-described.

What to change

Prioritized by impact on discoverability. You (or your docs platform) deploy these — Discry never touches your API.

  1. 01Publish an llms.txt at the docs root pointing to the CMA/CDA overviews, authentication, errors, rate limits, and the Hyperschema URL. This is the single highest-leverage fix: it unblocks two failing discovery checks (llmsTxt + llmsTxtQuality) and is a few hours of work given the .md pages already exist.
  2. 02Add an llms-full.txt that concatenates the core CMA/CDA markdown (overview, auth, records, errors, limits) into one agent-ingestible document, giving agents a single sub-15K-token entry point and lifting Token Efficiency from partial to pass.
  3. 03Add /docs URLs to the sitemap (or publish a dedicated docs sitemap and reference it from sitemap.xml). Today /sitemap.xml lists only marketing/blog/academy pages, so a crawler-based agent may never enumerate the API reference.
  4. 04Expose a .well-known/mcp.json (or otherwise advertise mcp.datocms.com via a discovery file) so MCP-aware agents can auto-detect the official remote MCP server instead of relying on blog posts and docs prose.
  5. 05Consider serving the JSON Hyperschema in OpenAPI 3.x form as well (or linking an OpenAPI export). The current spec is a valid, comprehensive JSON Hyperschema, but many agent toolchains expect OpenAPI/Swagger specifically and won't auto-ingest hyperschema.

Execution coverage · INFORMATIONAL, UNSCORED

Whether an agent can actually complete a call and recover from errors is the deeper Audit layer — documented here, but not part of the Discry Score.

API token (Bearer)OAuth2 (remote MCP server) Error format documented Rate limits documented Pagination documented Idempotency documented

Execution characteristics are documented to an exceptional standard: token-based Bearer auth, a machine-parseable JSON api_error body (code, doc_url, details, transient flag) backed by ~80 individually documented error codes each with recovery steps, explicit rate limits (60 req/3s) with x-ratelimit-limit/remaining/reset headers, and offset/limit pagination. No classic idempotency-key header, though custom record IDs and optimistic concurrency (stale-version detection) are documented.
