server:
  name: sapien-poq
  transport: http
  url: https://sapien-poq.up.railway.app/mcp
  authentication:
    scheme: bearer
    header: 'Authorization: Bearer poq_live_...'
    note: Uses the same Developer API keys as the /developer/v1 REST surface.
  characteristics:
  - Stateless across requests
  - Field names and error vocabulary match the /developer/v1 REST API
  - Presigned URLs handle file uploads (no bytes through tool calls)
  - Error codes use camelCase formatting
client_example:
  cursor_mcp_json: "{\n  \"mcpServers\": {\n    \"sapien-poq\": {\n      \"type\": \"http\",\n      \"\
    url\": \"https://sapien-poq.up.railway.app/mcp\",\n      \"headers\": { \"Authorization\": \"Bearer\
    \ poq_live_...\" }\n    }\n  }\n}\n"
  note: Other clients (Claude Code, VS Code) follow the same URL and header pattern.
