## 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:
- Payments & pricing, 50 against 35
- Maintenance & community, 85 against 74
- Transparency & trust, 72 against 60

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

### Hygraph (B)

Good for: Teams on Hygraph who want an agent to create, localise and publish entries, upload assets or change schema, with delete and unpublish kept out of reach on MCP.

Ahead on:
- Reliability, 89 against 80
- Schema & documentation, 78 against 51
- Security & auth, 63 against 56

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: GraphQL error bodies carry a message and a `requestId` with no machine-readable code, and only asset transformation 429 responses are documented with `Retry-After`

## 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.

**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.

## 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

### Hygraph

1. Send the Permanent Auth Token as `Authorization: Bearer <token>` to `https://<region>.hygraph.com/v2/<projectId>/<environment>`. Read the schema by introspection first, because every type is generated from the project's models
2. Mutations write to DRAFT. Call `publish<Model>` with `to: [PUBLISHED]` as a separate mutation, and pass `locales` to write or publish a localisation
3. 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
4. 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
5. 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 `<model>Version` and write the old values back
