FAQ from Workflows MCP Server

Why are there two approaches—MCP and direct API?

Due to technical challenges with current MCP SDK versions, the direct API offers a simpler, more reliable alternative for immediate use.

What are the runtime dependencies?

Node.js 18 or higher and npm or yarn are required.

Where does the weather data come from?

The server queries the OpenWeatherMap service for current weather data.

What transport protocols are supported?

The MCP approach uses HTTP with SSE; the simplified approach provides a plain RESTful endpoint.

Is authentication required?

The README does not mention any authentication mechanism; both approaches run without authentication.
