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**Hygraph.** Tokens are limited by model, stage, locale and action, the GraphQL schema is typed and introspectable, and a hosted MCP server rejects delete and unpublish operations. Error bodies carry a message without a machine code, there are no idempotency keys, audit logs are Enterprise only, and no data processing agreement, sub-processor list or security.txt was found.\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### Hygraph\n\n1. Send the Permanent Auth Token as `Authorization: Bearer \u003ctoken\u003e` to `https://\u003cregion\u003e.hygraph.com/v2/\u003cprojectId\u003e/\u003cenvironment\u003e`. Read the schema by introspection first, because every type is generated from the project's models\n2. Mutations write to DRAFT. Call `publish\u003cModel\u003e` with `to: [PUBLISHED]` as a separate mutation, and pass `locales` to write or publish a localisation\n3. Stay under the plan's limit for uncached requests (5 a second on Hobby, 25 on Growth) and its concurrent mutations (5 and 10). Back off exponentially on 429\n4. Upload an asset with `createAsset`, then POST the file to the returned pre-signed URL, or pass `uploadUrl` for a remote file. The asset stays `ASSET_CREATE_PENDING` until processed\n5. Schema changes go to the Management API through `@hygraph/management-sdk` or the MCP tool `submit_batch_migration`. Version restore has no documented mutation, so read `\u003cmodel\u003eVersion` and write the old values back\n\n## Questions\n\n### Which is better for AI agents, ButterCMS or Hygraph?\n\nHygraph scores 69.3 (B) on agent readiness against ButterCMS's 53.3 (D), and leads in 6 of 7 scored categories.\n\n### Do ButterCMS and Hygraph need an API key?\n\nButterCMS needs an API key. Hygraph takes an API key or an OAuth sign-in.\n\n### Can an agent call ButterCMS and Hygraph without installing anything?\n\nYes. ButterCMS has a hosted endpoint at https://api.buttercms.com/v2 and Hygraph at https://mcp.hygraph.com/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/buttercms-vs-hygraph.json, and with the fewest tokens: https://www.anchorterminal.com/compare/buttercms-vs-hygraph.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"buttercms\", \"b\": \"hygraph\"}`.
