Watch for

The MCP server's default group loads 78 tools, including nine deletes, with no readOnlyHint or destructiveHint annotations and no read-only switch

DatoCMS BB

Good for Teams on DatoCMS who want an agent to create, translate and publish records, upload assets or change models, testing first in a sandbox environment.

Verdicts

Contentstack

The Content Management API has a public OpenAPI file, OAuth scopes that separate read, write and publish, read-only management tokens and a stack audit log. A free plan needs no card. The MCP server loads 78 tools by default with no annotations or read-only switch, and the limit=0 behaviour changed on 11 September 2026 without advance notice.

DatoCMS

The Content Management API publishes a JSON Hyper-Schema for 202 operations, 100 documented error codes and rate-limit headers, and the hosted MCP server adds OAuth with three access levels. There are no idempotency keys, the only official client library is JavaScript, audit logs are Enterprise only, and prices are in euros with no machine payment route.

Before you call either

Contentstack

  1. Pick the base URL for the stack's region first. North America on AWS is https://api.contentstack.io, and the other six regions use contentstack.com hosts
  2. Send api_key and authorization headers on every Content Management API call. Ask for a read-only management token when the task only reads
  3. Page with limit (100 at most), skip and include_count=true. limit=0 no longer returns everything
  4. Stay under 10 reads and 10 writes a second per organisation, and one bulk request a second. Watch X-RateLimit-Remaining and back off on 429
  5. Start the MCP server with --groups cma only, and add cma-extended when the task needs audit logs or version history. Publishing and deleting need no confirmation

DatoCMS

  1. Send X-Api-Version: 3 and Accept: application/json on every request, with Content-Type: application/vnd.api+json on writes
  2. Records are items, models are item_types and assets are uploads in every path and payload
  3. Save a record, then call the publish endpoint as a separate PUT. Send meta.current_version on updates and re-fetch on STALE_ITEM_VERSION
  4. Stay under 60 requests every 3 seconds. On 429 wait the seconds in x-ratelimit-reset, and retry any error whose body has transient set to true
  5. Fork a sandbox environment for schema changes and promote it when checked. Use POST /items/validate to test a payload without saving it

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
