# Legacy MCP route (closed)

`POST /api/mcp` - [human page](https://aicdapi.com/api-reference#postPrelaunchMcp)

**Release status.** Closed

A legacy MCP route that always refuses with 403. It is not an alias of /api/v1/mcp and no credential changes the outcome. It exists so a client that guesses the older path receives a clear explanation instead of an unhandled error.

**Authentication.** No credentials. This endpoint is public.

### Example request

```bash
curl -X POST 'https://aicdapi.com/api/mcp'
```

### Errors

| Status | `error.code` | Description |
| --- | --- | --- |
| **403** | `mcp_prelaunch` | Always. MCP access is closed on this route. |
