## 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:
- Security & auth, 69 against 63
- Maintenance & community, 82 against 74
- Transparency & trust, 73 against 60

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

### 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 71
- Agent ergonomics, 72 against 67
- Payments & pricing, 35 against 30

Also in its favour:
- No incidents deducted, where Contentstack loses 3 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

**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.

**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

### 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

### 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
