Swagger/Postman MCP Server

Swagger/Postman MCP Server is an MCP server that ingests and serves Swagger or OpenAPI specifications alongside Postman collections as executable Model Context Protocol tools. Designed for software engineers, API developers, and technical product managers, this server bridges documented REST APIs directly to AI agents. It relies on a local config.json file to manage target endpoints, collection definitions, and necessary authentication credentials. By converting standard API definitions into callable schema definitions, the server allows language models to automatically construct valid HTTP requests, execute them against live endpoints, and process JSON responses. This eliminates the need to manually implement custom MCP integrations for existing backend services, enterprise resource planning platforms, customer relationship managers, or external developer tools. Users can connect their development assistants directly to complex microservice architectures and test environments by simply supplying pre-existing documentation artifacts, streamlining automated API testing, workflow execution, and direct data extraction through conversational AI interfaces.

How to install and configure Swagger/Postman MCP Server

1. Visit the project repository at https://github.com/MCP-Mirror/AlanGreyjoy_swag-mcp to review setup instructions and prerequisite packages. 2. Clone the repository to your local system. 3. Prepare the required config.json file in the root directory to define your Swagger, OpenAPI, or Postman source files and provide necessary authentication credentials. 4. Open your client configuration file, such as the Claude Desktop or Cursor configuration JSON. 5. Register the server under the mcpServers configuration object using the exact execution command and path specified in the project repository. 6. Restart your MCP client to verify that your configured API tools load properly.

What you can do with Swagger/Postman MCP Server

• Expose existing OpenAPI or Swagger REST endpoints directly to conversational assistants for automated backend administration. * Execute complex Postman collection workflows through natural language prompts without manual code configuration. * Test and debug live web services by letting language models formulate parameter-accurate API payloads. * Extract records from internal enterprise services using standard authentication defined in the configuration file.

Part of MCP Servers

What is Swagger/Postman MCP Server?

Swagger/Postman MCP Server is an integration tool that reads OpenAPI, Swagger, and Postman files, converting their endpoint definitions into executable Model Context Protocol tools. This enables AI models to interact with existing REST APIs using structured inputs.

How do I configure Swagger/Postman MCP Server?

Configuration requires creating a config.json file as outlined in the repository. This file specifies the location of your API definitions and sets up the required authentication tokens or parameters for communicating with your live services.

Which MCP clients work with Swagger/Postman MCP Server?

The server works with standard MCP-compliant clients such as Claude Desktop, Cursor, and other custom developer environments that support external tool calls over the Model Context Protocol.

What can Swagger/Postman MCP Server do?

It translates API schemas into callable tools so that AI assistants can formulate requests, pass authentication headers, call live HTTP endpoints, and parse the returned JSON data to answer user queries or automate operational tasks.
