About 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. Functionality is derived from the official Postman OpenAPI specification. It exposes tool groups for collections, environments, APIs, authentication/authorization, mocks, monitors, users, workspaces, and additional features such as webhooks and the private API network. It runs over stdio and is intended for use with MCP clients like Claude Desktop and Cline.
