DatoCMS vs Prismic

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.

Prismic

The hosted MCP server stages every write as a draft in a release, cannot delete, and publishes only when a user with the Publisher role asks. Write tokens for the Migration, Asset and Types APIs have no scopes, no OpenAPI file was found, writes are limited to one request a second, and the acceptable use policy forbids access by scripts.

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

Prismic

1. Ask a repository Administrator to activate Prismic MCP in Settings first. Activation can take several minutes, and each environment has its own setting
2. Call list_repositories, then get_custom_type or get_shared_slice for the empty content template before create_document
3. Create a release with create_release and write into it. Call publish_release only on an explicit request, because a publish cannot be undone through MCP
4. For the Migration API send Authorization: Bearer <write token> and a repository header, one page a request, one request a second, and keep each returned id for later PUT calls
5. Upload media first (upload_asset or POST to https://asset-api.prismic.io/assets) and reference the asset id in image and media link fields
