## 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.

Also in its favour:
- Runs on your own machine

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

### DatoCMS (BB)

Good for: Teams on DatoCMS who want an agent to create, translate and publish records, upload assets or change models, testing first in a sandbox environment.

Ahead on:
- Reliability, 80 against 71
- Schema & documentation, 85 against 77
- Agent ergonomics, 78 against 67
- Security & auth, 77 against 69
- Payments & pricing, 35 against 30
- Transparency & trust, 80 against 73

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Contentstack loses 3 points for them

Watch for: No idempotency keys in the reviewed documentation. Safe retries rest on optimistic locking and the JavaScript client's automatic retry

## 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.

**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.

## 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

### 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
