Specrun

Specrun is an MCP server that converts OpenAPI specification files (OpenAPI 3.x and Swagger 2.0) placed in a folder into ready-to-use tools for API interaction across any MCP client. It automates tool generation, authentication management, server URL configuration, and supports batch operations, making it ideal for developers and teams who need to quickly turn API specs into interactive tools without complex configuration. Built for use with Node.js and FastMCP, it streamlines the process of working with multiple APIs via agent-guided UI or CLI.
