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**Sanity.** Sanity publishes 26 OpenAPI specs covering 225 operations, and its hosted MCP server saves edits to drafts or release versions, with publishing as a separate call. The Content Lake does not run schema validation on API writes, and custom roles that limit a token to one dataset or document type are sold only on Enterprise plans.\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### Sanity\n\n1. Pin a static dated version in every URL, such as `v2025-02-19`. Omitting `apiVersion` in `@sanity/client` falls back to `v1`.\n2. Validate documents against the schema yourself before an HTTP write, or run `sanity documents validate` afterwards. The Content Lake does not enforce schema rules.\n3. Back off on 429 for mutations yourself. `@sanity/client` retries queries five times but never retries mutations. The limit is 25 mutations a second per IP.\n4. Over MCP, call `create_version` before `patch_documents` when editing inside a release, then patch the returned version ID with the same `releaseId`.\n5. Use GROQ projections and slices to size results. MCP query responses are limited to 64 KiB, and a blocked Free project answers 402 with `plan_limit_reached`.\n\n## Questions\n\n### Which is better for AI agents, Contentstack or Sanity?\n\nSanity scores 73.7 (BB) on agent readiness against Contentstack's 64 (B), and leads in 6 of 7 scored categories.\n\n### Do Contentstack and Sanity need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Contentstack and Sanity without installing anything?\n\nYes. Contentstack has a hosted endpoint at https://api.contentstack.io and Sanity at https://api.sanity.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/contentstack-vs-sanity.json, and with the fewest tokens: https://www.anchorterminal.com/compare/contentstack-vs-sanity.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"contentstack\", \"b\": \"sanity\"}`.
