Overview

What is Postman MCP Generator?

FAQ from Postman MCP Generator

What Node.js version is required?

Node.js v18+ is required (v20+ recommended). Lower versions may lack fetch, which the generated tools use for HTTP calls.

How do I configure API keys?

Set environment variables in .env – one per workspace (e.g., ACME_API_KEY=...). The generated tools read these variables to authenticate requests. You can manually adjust the logic if needed.

How can I test the MCP server?

Use the Postman Desktop Application with a STDIO MCP request pointing to node <absolute‑path>/mcpServer.js. Alternatively, connect it to Claude Desktop by adding a JSON entry in the MCP configuration.

How do I add new tools to the server?

Visit the Postman MCP Generator, select new API requests, download the generated server, copy the new tool files into your project’s tools/ folder, and update tools/paths.js.
