## Which one, for what

### Ghost (C)

Good for: A publication, blog or newsletter where an agent drafts posts and a person or a higher role publishes.

Ahead on:
- Agent ergonomics, 69 against 63
- Security & auth, 56 against 50
- Payments & pricing, 50 against 35
- Maintenance & community, 85 against 79

Also in its favour:
- Open source

Watch for: No OpenAPI or other machine-readable description of the Admin API was found in the docs or the repository

### Prismic (C)

Good for: Teams already on Prismic who want an agent to bulk-edit, localise or migrate pages into releases for human review.

Ahead on:
- Schema & documentation, 60 against 51

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card
- No incidents deducted, where Ghost loses 7 points for them

Watch for: No OpenAPI file for the Migration, Asset or Types APIs in the reviewed documentation. The Types API links a Postman collection

## Verdicts

**Ghost.** A create needs only a title, updates are checked against `updated_at` so a stale write is refused, and a Contributor's staff token can draft without being able to publish. The Admin API has no OpenAPI file and one fixed permission set per integration, and 20 security advisories were published between 3 September and 1 October 2026.

**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.

## Before you call either

### Ghost

1. Sign a fresh HS256 token for each batch of calls. Decode the hex secret to bytes, set `kid` to the key id, `aud` to `/admin/` and `exp` at most 5 minutes ahead
2. Set `status` to `draft` on every create unless told to publish, and publish later with a PUT that sets `status` to `published`
3. GET the post before each PUT and send its `updated_at` back. Tags and authors in a PUT replace the existing lists
4. Send content as a Lexical JSON string, or add `?source=html` and send `html`. The HTML conversion is lossy unless wrapped in an HTML card
5. Page through lists with `limit` up to 100 and `page`. Since Ghost 6.0 `limit=all` returns 100 items without an error

### 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
