# Postman Tool Generation MCP Server An MCP server that generates AI agent tools from Postman collections and requests. This server integrates with the Postman API to convert API endpoints into type-safe code that can be used with various AI frameworks.

Model Context Protocol (MCP) is a [new, standardized protocol](https://modelcontextprotocol.io/introduction) for managing context between large language models (LLMs) and external systems. In this repository, we provide an installer as well as an MCP Server for [Postman Tool Generation API](https://api.getpostman.com/postbot/generations/tool). This lets you use [Claude Desktop](https://claude.ai/download), or any MCP Client like [Cline](https://github.com/cline/cline), to use natural language to accomplish things on your Postman account, e.g.: * `Create an AI tool for: collectionID: 12345-abcde requestID: 67890-fghij typescript openai`

Postman Tool Generation Server MCP server

## Features - Generate TypeScript/JavaScript code from Postman collections - Support for multiple AI frameworks (OpenAI, Mistral, Gemini, Anthropic, LangChain, AutoGen) - Type-safe code generation - Error handling and response validation ## Demo

Demonstrating the newly-released MCP server to explore Postman Tool Generation API

## Setup 1. Install dependencies: ```bash npm install ``` 2. Build the server: ```bash npm run build ``` 3. Configure the MCP settings by adding the following to your Claude settings file (`cline_mcp_settings.json`): ```json { "mcpServers": { "postman-ai-tools": { "command": "node", "args": [ "/path/to/postman-tool-generation-server/build/index.js" ], "env": { "POSTMAN_API_KEY": "your-postman-api-key" }, "disabled": false, "autoApprove": [] } } } ``` ## Usage The server provides a single tool called `generate_ai_tool` with the following parameters: ```typescript { collectionId: string; // The Public API Network collection ID requestId: string; // The public request ID language: "javascript" | "typescript"; // Programming language to use agentFramework: "openai" | "mistral" | "gemini" | "anthropic" | "langchain" | "autogen"; // AI framework } ``` ### Example ```typescript // Using the tool through MCP const result = await use_mcp_tool({ server_name: "postman-ai-tools", tool_name: "generate_ai_tool", arguments: { collectionId: "your-collection-id", requestId: "your-request-id", language: "typescript", agentFramework: "openai" } }); ``` ### Generated Code The tool generates type-safe code that includes: - Type definitions for request/response - Error handling - API integration - OpenAI function definitions - Documentation and examples ## Development 1. Install dependencies: ```bash npm install ``` 2. Make changes to `src/index.ts` 3. Build the server: ```bash npm run build ``` 4. Restart the Claude app to load the updated server ## Environment Variables - `POSTMAN_API_KEY`: Your Postman API key (required) ## Error Handling The server includes comprehensive error handling for: - Invalid parameters - API failures - JSON parsing errors - Network issues Error responses include detailed messages to help diagnose issues. ## Contributing Contributions are welcome!
