      summary: Developer MCP server (Streamable HTTP, JSON-RPC)
      description: 'Model Context Protocol endpoint for AI assistants and agents. Send JSON-RPC 2.0 messages (initialize, tools/list, tools/call) with your API key as the bearer token. Tools call the same /v1 service, so jobs are quoted, reserved and billed exactly like the HTTP API. Stateless: GET returns 405. An unauthenticated request gets 401 with a WWW-Authenticate: Bearer challenge.'
