}This one needs environment variables set before it will start:
FACTUAREA_API_KEY (Factuarea API key. The prefix selects the environment: fact_test_ for the isolated sandbox, fact_live_ for the real company. Without it the server starts and refuses every call with an actionable error.), FACTUAREA_MCP_URL (Endpoint of the hosted server. Defaults to https://mcp.factuarea.com.), FACTUAREA_REQUEST_TIMEOUT_MS (Ceiling for a single call, in milliseconds. Defaults to 120000.).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
