A standalone MCP server for API testing and management, allowing AI assistants to interact with RESTful APIs through natural language.
Postmancer is an MCP (Model Context Protocol) server that enables AI assistants like Claude to make HTTP requests, manage collections of API endpoints, and test API responses. It provides similar functionality to tools like Postman or Insomnia but designed specifically for AI assistants.
