## Which one, for what

### 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 79
- Schema & documentation, 78 against 68

Also in its favour:
- No incidents deducted, where Storyblok 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`

### Storyblok (B)

Good for: Teams already on Storyblok who want an agent to draft, translate and publish stories or change component schemas under scoped, per-space permissions.

Ahead on:
- Agent ergonomics, 78 against 72
- Security & auth, 73 against 63
- Maintenance & community, 80 against 74
- Transparency & trust, 80 against 60

Watch for: The Management API's OpenAPI spec sits in a private repository. Only the Content Delivery API has a public spec (OpenAPI 3.1, 14 operations)

## Verdicts

**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.

**Storyblok.** The hosted MCP server covers the whole Management API with seven tools, OAuth scopes split into read, write and publish per space, and a confirmation step on deletes. The Management API has no public OpenAPI spec, no idempotency keys and no monitor on the public status page, and publishing is a GET request.

## Before you call either

### 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

### Storyblok

1. Pick the base URL by the space's region (mapi.storyblok.com for the EU, api-us, api-ca or api-ap otherwise). A token sent to the wrong region fails
2. Create stories without `publish` to keep them as drafts, then call the publish endpoint. It is a GET, so never prefetch or blindly retry it
3. Write translations as `field__i18n__<code>` keys inside the same content object, and set the component field to translatable first
4. Upload an asset in three steps (signed response, POST to S3, finish upload). Through MCP the S3 step needs shell access for curl
5. Stay under 3 calls a second on Starter and 6 on paid plans, and back off exponentially on 429. Saves that break a field's max_length return 422
