          "13 May 2026. Strapi published two critical advisories. GHSA-rjg2-95x7-8qmx (CVE-2026-27886) leaked sensitive data through relation filters in versions 4.0.0 to 5.36.1, and GHSA-3xcq-8mjw-h6mx (CVE-2026-22599) was SQL injection in the Content-Type Builder up to 5.33.1 and 4.26.0. Both were fixed in earlier releases (5.37.0, 5.33.2 and 4.26.1) and published by the vendor, and we found no report of exploitation, so we deduct 6 of a possible 15. https://github.com/strapi/strapi/security/advisories/GHSA-rjg2-95x7-8qmx ; https://github.com/strapi/strapi/security/advisories/GHSA-3xcq-8mjw-h6mx"

The Write API is a paid add-on from the $249 plan, capped at 2,000 or 5,000 calls a month. Writes answer 202 with no identifier, support rotates tokens, and the terms are an undated website document.\n\n**Strapi.** The built-in MCP server shows an agent only the tools, fields and locales its Admin token permits, and content tools create drafts by default. Rollback is the limit. Content History is a paid feature and records admin panel edits only, so API and MCP writes leave no version to restore, and the MCP server can't upload files.\n\n## Before you call either\n\n### ButterCMS\n\n1. End every path with a slash. A missing slash returns a 301, and the vendor counts the redirect and the retry as two API calls\n2. Send the write token only as `Authorization: Token \u003ctoken\u003e`. The `auth_token` query parameter works for reads only\n3. On page creation send every field key of the page type, with empty strings for fields left blank\n4. A 202 means queued, not saved. Read the entry back with `preview=1` to confirm, and check a slug exists before retrying a create\n5. Call the REST API directly for writes. The JavaScript SDK 3.0.3 has list, retrieve and search methods only\n\n### Strapi\n\n1. Pass `status=draft` on every REST POST and PUT. Without it the Content API publishes the entry at once\n2. Use an Admin token for `/mcp` and admin routes and an API token for `/api`. Each kind is rejected on the other's routes\n3. Upload files with multipart POST to `/api/upload` first, then reference the returned file id in the entry. MCP tools can't upload\n4. Call `media_delete_assets` and `media_delete_folder` without `dryRun` first to preview, and take asset ids only from `media_list_assets`\n5. Keep your own copy of an entry before updating it. API and MCP writes create no Content History version\n\n## Questions\n\n### Which is better for AI agents, ButterCMS or Strapi?\n\nStrapi scores 65.7 (B) on agent readiness against ButterCMS's 53.3 (D), and leads in 6 of 7 scored categories.\n\n### Do ButterCMS and Strapi need an API key?\n\nBoth need an API key.\n\n### Can an agent call ButterCMS and Strapi without installing anything?\n\nButterCMS has a hosted endpoint at https://api.buttercms.com/v2. No hosted endpoint is listed for Strapi.\n\n### Are ButterCMS and Strapi open source?\n\nNo open-source release is listed for ButterCMS. Strapi is open source (MIT for the Community Edition. Code under ee/ directories is under Strapi's Enterprise Edition licence, and Strapi Cloud is a paid service under its own terms).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/buttercms-vs-strapi.json, and with the fewest tokens: https://www.anchorterminal.com/compare/buttercms-vs-strapi.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"buttercms\", \"b\": \"strapi\"}`.
