Overview

Postman MCP Server is a Node.js Express application that serves as an API wrapper around Postman/Newman functionality, enabling users to manage Postman collections, create mock servers, and run API tests.

To use the Postman MCP Server, clone the repository, install the dependencies, configure your environment with your Postman API key, and run the server. You can then access various API endpoints to create test scenarios, generate mock servers, and run tests.

Test scenario management using Postman collections. - Mock server generation based on Postman collections. - API testing capabilities using Newman.

Managing and executing API tests in a development environment.
Creating mock servers for testing API responses.
Organizing and running test scenarios for various API endpoints.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "postman-mcp-server-freebeiro": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-postman-mcp-server-freebeiro"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "postman-mcp-server-freebeiro": {
