Automated testing for Model Context Protocol servers. Ship MCP Servers with confidence.
This is a testing framework for developers building Model Context Protocol (MCP) servers. It helps ensure that your AI assistants (like Claude or ChatGPT) can reliably connect and interact with external tools, databases, or APIs through your MCP server. You write automated tests that check the functionality of your tools, and the framework reports on passing or failing tests, allowing you to ship your AI agent integrations with confidence.
