# MCPJam

> Test MCP servers across AI clients with inspection tools and repeatable evaluations.

MCPJam is a testing environment for developers building MCP servers. It lets teams call tools, inspect traces, and compare how the same prompt behaves across supported AI clients. Developers can use it locally, in a browser, or through desktop applications while iterating on a server.

Evaluation suites provide repeatable checks for releases, with results covering outcomes, latency, token use, and tool calls. Simulated user journeys explore how different personas interact with a server, recording sessions for review. The combination of interactive inspection and recurring tests helps teams investigate failures before introducing a changed server to their users.
