Interactively test tools, prompts, resources, and authorization across 16 client configurations and 170+ models. Run evals on test cases, get insights on what's breaking, and gate regressions to secure every deployment. 🚀 Quick start Open the hosted app. No install needed. 👉 app.mcpjam.com ... or run MCPJam locally for HTTP/S and local STDIO servers: 👋🏽 Why MCPJam Clients like ChatGPT, Claude, and Cursor all read your server differently. MCPJam catches those differences, shows where your server breaks, and tells you how to fix it: - Inspect & debug : Explore your server's tools, resources, and prompts in one place. Test prompts from real LLMs, with full visibility & traces on every JSON-RPC message and OAuth exchange. - Cross-client evals : Score agent behavior across 16 client configurations — ChatGPT, Claude, Cursor, Copilot, and more — to understand how your MCP integrations perform across all users. Track accuracy, latency, and tool-call performance over time. - Security & reliability : Automate conformance & behavior checks in CI/CD to catch regressions before they reach production. 🔨 Features Capability What it does -------------------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------","default_branch":null,"files":null,"tree":[],"storefront":"/r/MCPJam","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/MCPJam/inspector/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
