## Which one, for what

### Contentstack (B)

Good for: Teams already on Contentstack, or starting on its free plan, who want an agent to draft, localise, release and publish structured content with scoped credentials and an audit trail.

Ahead on:
- Schema & documentation, 77 against 51
- Security & auth, 69 against 56

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Free to start without a card

Watch for: The MCP server's default group loads 78 tools, including nine deletes, with no readOnlyHint or destructiveHint annotations and no read-only switch

### Ghost (C)

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

Ahead on:
- Reliability, 80 against 71
- Payments & pricing, 50 against 30

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

## Verdicts

**Contentstack.** The Content Management API has a public OpenAPI file, OAuth scopes that separate read, write and publish, read-only management tokens and a stack audit log. A free plan needs no card. The MCP server loads 78 tools by default with no annotations or read-only switch, and the `limit=0` behaviour changed on 11 September 2026 without advance notice.

**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.

## Before you call either

### Contentstack

1. Pick the base URL for the stack's region first. North America on AWS is https://api.contentstack.io, and the other six regions use contentstack.com hosts
2. Send `api_key` and `authorization` headers on every Content Management API call. Ask for a read-only management token when the task only reads
3. Page with `limit` (100 at most), `skip` and `include_count=true`. `limit=0` no longer returns everything
4. Stay under 10 reads and 10 writes a second per organisation, and one bulk request a second. Watch `X-RateLimit-Remaining` and back off on 429
5. Start the MCP server with `--groups cma` only, and add `cma-extended` when the task needs audit logs or version history. Publishing and deleting need no confirmation

### 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
