MCPJam

About

MCPJam is a testing and evaluation platform for MCP (Model Context Protocol) servers, letting teams simulate user swarms with different goals, watch real user sessions, and convert those workflows into repeatable evals across AI clients like ChatGPT, Claude, and Cursor. It addresses the visibility gap that appears when a product's users interact through an AI client and MCP server rather than the product's own interface, so teams can no longer see what was prompted or whether the agent's outcome was correct.
