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.\n\n**Storyblok.** The hosted MCP server covers the whole Management API with seven tools, OAuth scopes split into read, write and publish per space, and a confirmation step on deletes. The Management API has no public OpenAPI spec, no idempotency keys and no monitor on the public status page, and publishing is a GET request.\n\n## Before you call either\n\n### Contentstack\n\n1. 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\n2. Send `api_key` and `authorization` headers on every Content Management API call. Ask for a read-only management token when the task only reads\n3. Page with `limit` (100 at most), `skip` and `include_count=true`. `limit=0` no longer returns everything\n4. 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\n5. 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\n\n### Storyblok\n\n1. Pick the base URL by the space's region (mapi.storyblok.com for the EU, api-us, api-ca or api-ap otherwise). A token sent to the wrong region fails\n2. Create stories without `publish` to keep them as drafts, then call the publish endpoint. It is a GET, so never prefetch or blindly retry it\n3. Write translations as `field__i18n__\u003ccode\u003e` keys inside the same content object, and set the component field to translatable first\n4. Upload an asset in three steps (signed response, POST to S3, finish upload). Through MCP the S3 step needs shell access for curl\n5. Stay under 3 calls a second on Starter and 6 on paid plans, and back off exponentially on 429. Saves that break a field's max_length return 422\n\n## Questions\n\n### Which is better for AI agents, Contentstack or Storyblok?\n\nStoryblok scores 67.7 (B) on agent readiness against Contentstack's 64 (B), and leads in 5 of 7 scored categories. Contentstack leads on schema \u0026 documentation.\n\n### Do Contentstack and Storyblok need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Contentstack and Storyblok without installing anything?\n\nYes. Contentstack has a hosted endpoint at https://api.contentstack.io and Storyblok at https://mapi.storyblok.com/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/contentstack-vs-storyblok.json, and with the fewest tokens: https://www.anchorterminal.com/compare/contentstack-vs-storyblok.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"contentstack\", \"b\": \"storyblok\"}`.
