Who MCPJam is for
The same platform, in your language: developers, engineering managers, PMs, AI and platform leads, marketers, MCP client vendors, and enterprise.
Pick your role
Reproduce any MCP failure in minutes: run your server through a real agent, read the trace, debug OAuth step by step, and gate PRs with evals. Free and open source.
Make MCP reliability a merge gate: evals on every PR, failures your team can reproduce, and client coverage maintained for you instead of by your engineers.
Know if your MCP integration is launch-ready: pass rates on realistic requests, failure patterns named, and tester sessions you can replay before users hit them.
Standardize how every team tests MCP: one platform for local testing, CI gates, and cross-client coverage — an open-source local inspector with a hosted team platform.
ChatGPT and Claude are where your users work now. Ship an MCP integration that performs in every client, with cross-client test evidence before every launch.
MCPJam tracks what the major AI clients support and how servers behave in each. If you build an MCP client, stay at parity with ChatGPT and Claude and expose the capabilities server developers rely on.
Adopt MCP testing without new risk: SSO/SAML, RBAC, custom DPA, audit retention, SOC 2 (in progress), CI/CD reporting, and an SLA. Strictly pre-production, and it never touches live traffic.
