# Prismic (slim)

> Prismic is a hosted headless CMS and page builder. Agents write to it through the official hosted MCP server (16 tools that stage changes in releases) or the Migration, Asset and Types APIs with a write token.

- Full: https://www.anchorterminal.com/tools/prismic.md (~7,900 tokens) · this version ~2,080 tokens · JSON https://www.anchorterminal.com/tools/prismic.json · canonical https://www.anchorterminal.com/tools/prismic

**C · 61.9/100 · rank #410 of 842 · #10 in CMS & website publishing · not agent-ready · confidence medium**


Assessment: 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.

- Probe metrics: not measured yet (probes haven't run)
- Surfaces: Hosted MCP server for content, Migration API for pages, Asset API for media, Types API for content models, Content API and GraphQL for reads, Prismic CLI for repository settings and models
- MCP server: `https://mcp.prismic.io/mcp` over HTTP with OAuth. On by default for new repositories, and an Administrator or Owner activates or deactivates it per repository and per environment
- MCP tools: 16. Discovery `list_repositories`, `list_custom_types`, `list_shared_slices`, `list_locales`, `list_releases`, `list_document_versions`. Read `search_documents`, `search_assets`, `get_document`, `get_custom_type`, `get_shared_slice`. Write `create_release`, `create_document`, `update_document`, `upload_asset`, `publish_release`
- Write APIs: `https://migration.prismic.io/documents` (POST, PUT), `https://asset-api.prismic.io/assets` (GET, POST, PATCH, DELETE), `https://customtypes.prismic.io` (`/customtypes`, `/slices`, insert, update, DELETE)
- Credentials: MCP uses OAuth authorisation code with PKCE S256, dynamic client registration, refresh tokens and revocation, with no scopes in the server metadata. Sign-ins expire after 90 days. The write APIs take a repository write token as a Bearer header plus a `repository` header
- Rate limits: Migration API one request a second per repository, Asset API one request a second, Content API 200 requests a second uncached. No MCP limit found
- Drafts and versions: Migration API and MCP writes are drafts in a release. `list_document_versions` lists draft, published, archived and release versions. Full revision history on every plan per the pricing page. No unpublish or rollback tool in MCP
- Assets: `upload_asset` fetches from a URL. The Asset API takes multipart uploads, one asset a request, with `limit`, `cursor` and `keyword` on the list call. The acceptable use policy caps files at 20 MB

## Before you call it

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

## Connect

```bash
npm install @prismicio/client @prismicio/migrate
```

```bash
curl --location --request GET 'https://customtypes.prismic.io/customtypes' \
  --header 'repository: your-repo-name' \
  --header 'Authorization: Bearer <token>'
```
