`GET /mcp`

Probe MCP endpoint authentication and protocol support.

## Access

Use a credential with the authentication scheme documented in the API contract.

Provider access, workspace membership, and agent grants are enforced separately. A token does not expand access to a repository or resource. [Set up developer access](/docs/build/developer-access).

## Call the endpoint

Replace path placeholders and your credential. For body operations, create `request.json` using the required fields above; this command does not invent resource identifiers or consent.

```bash
curl --request GET \
  'https://commentary.dev/mcp' \
  --header 'Authorization: Bearer <your-token>'
```

## Responses

| Status | Meaning | Payload |
| --- | --- | --- |
| `200` | Authenticated GET is accepted. | object |
| `401` | Bearer authentication challenge with protected resource metadata. | [ExternalError](/docs/reference/schemas/external-error) |

### Successful response fields

Value type: object.

## Recover from errors

Use the returned status and error body. Correct invalid fields before retrying; reconnect or narrow the target for authentication and permission errors. For conditional writes, reload the latest version before preparing a new request. Respect rate-limit headers and retry only when the operation’s idempotency contract permits it.
