About MCPJam
MCPJam provides a platform for testing and debugging Model Context Protocol servers through swarms, user testing, evaluations, and CI/CD integration. It allows developers to simulate user scenarios across multiple clients such as ChatGPT and Claude in parallel, identifying edge cases that automated tests may miss. The platform includes tools for OAuth debugging, cross-client testing, and protocol conformance checks. User testing features measure sentiment and usability gaps by observing real user interactions with the server. Evals turn user workflows into repeatable test suites that can be re-run automatically across preferred clients to ensure consistent behavior. CI/CD actions integrate with pull requests to block failures before they ship, enforcing quality gates on model behavior and security checks. The platform supports local testing via CLI or SDK, enabling integration into development workflows.

Frequently asked questions about MCPJam
What does MCPJam do?
MCPJam provides a platform for testing and debugging Model Context Protocol servers through swarms, user testing, evaluations, and CI/CD integration. It simulates user scenarios across multiple clients like ChatGPT and Claude, identifies edge cases, and enforces quality gates on model behavior and security checks.
Who is MCPJam designed for?
The platform is designed for developers, product managers, engineering managers, AI and platform leads, enterprises, marketers, and MCP clients. It helps each group validate MCP server functionality, usability, and reliability before deployment.
How does MCPJam integrate with CI/CD workflows?
MCPJam integrates with CI/CD by running durable evaluations on pull requests, blocking merges if tests fail. It enforces quality gates such as protocol conformance, OAuth and security checks, and cross-client evaluations to catch regressions before they ship.
Can MCPJam test MCP servers locally?
Yes, MCPJam supports local testing via CLI or SDK, allowing developers to integrate it into their development workflows. The CLI command 'npx @mcpjam/inspector@latest' enables quick setup and testing of MCP servers.
What types of testing does MCPJam offer?
MCPJam offers swarms for simulating multiple user scenarios in parallel, user testing to measure sentiment and usability gaps, evals to turn workflows into repeatable test suites, and CI/CD actions to enforce quality gates on pull requests.
How does MCPJam handle OAuth and security debugging?
MCPJam includes an OAuth & EMA debugger that pinpoints the exact step where authentication breaks, helping developers resolve security and authorization issues in their MCP servers.
