Overview
What is Postman MCP Server?
Postman MCP Server is a TypeScript-based MCP server that integrates with the Postman API, providing comprehensive management of Postman collections, environments, and APIs. It is part of the Model Context Protocol (MCP) initiative from Anthropic and is based on the official Postman API OpenAPI specification.
How to use Postman MCP Server?
Install via Smithery (npx -y @smithery/cli install postman-api-server --client claude) or clone the repository, install dependencies (pnpm install), build (pnpm run build), and optionally run in watch mode.

Configure the server in your Claude Desktop or Cline MCP settings by adding a JSON entry with the command pointing to the built index.js file.
