FAQ from MCP API Server

What are the prerequisites for running MCP API Server?

Node.js 16 or higher and npm are required.

How do I integrate this server with VS Code?

Create a .vscode/mcp.json file with a stdio configuration pointing to the server, replacing the path with your absolute project path, then reload VS Code.

What tools does MCP API Server expose?

It exposes two tools: auth for managing authentication tokens (actions: set, check, clear) and vehicle_api for retrieving vehicle data from an external API.

How does authentication work?

Authentication uses token‑based security. You set a token with the auth tool, check its status, or clear it. The server tracks the authentication state for subsequent API calls.

What transport does the server use?

The server uses stdio transport, as shown in the VS Code integration configuration.
