Voir le guide →inspector est un projet de développement open source, créé par MCPJam (MCPJam/inspector sur GitHub). Il compte 2 246 étoiles sur GitHub et 295 forks, il est publié sous la licence Apache-2.0 et a été mis à jour pour la dernière fois sur GitHub le 8 octobre 2026.
MCPJam Inspector: chat with, inspect, debug, and evaluate MCP servers across clients and models.
Decide how you will run it: hosted app for HTTPS servers, or locally via npx or desktop for STDIO and local servers.
Start the inspector with npx (or clone and build the Docker image if you prefer containers).
Connect your MCP server, then explore its tools, resources, and prompts and run them by hand with full JSON-RPC logs.
Chat against the server in the playground, debug OAuth if you use it, and define eval test cases to catch regressions in CI.
A cross-client chat interface that emulates host UIs and shows every tool call, agent step, and JSON-RPC message in one timeline, including a widget emulator for app UIs.
Step-by-step visualisation of OAuth and related flows, with guided conformance checks across several MCP protocol versions and registration methods.
Run tools, resources, templates, prompts, and elicitation flows by hand with complete request and response observability.
Define test cases with expected tool calls and run them across many models and client configurations, tracking accuracy and latency over time.
Shared server groups sync in real time for teams, and reusable skills can extend model behaviour inside the playground.
Probe servers and run checks from the terminal, drive inspections programmatically, and gate pull requests with conformance and eval runs.
There is no published image, so Docker users build from source and keep it bound to localhost.
git clone https://github.com/MCPJam/inspector.git
cd inspector
docker build -t mcpjam/mcp-inspector:local -f mcpjam-inspector/Dockerfile .This is the quickest local route for HTTP/S and STDIO servers.
npx @mcpjam/inspector@latestOpen the printed localhost URL, add your MCP server, and run its tools in the playground. # see README for connection steps
docker run -p 127.0.0.1:6274:6274 mcpjam/mcp-inspector:local # alternative Docker routeIt is maintained by the MCPJam team on GitHub.
Yes, the inspector is open source under Apache License 2.0 per its README; MCPJam also offers a hosted app and paid platform features around it.
Not for inspecting a server by hand. To chat against it with models or run LLM-based evals you use your own model access through the platform.
The original MCP Inspector from the protocol project focuses on basic manual testing; MCPJam adds cross-client playgrounds, OAuth debugging, evals, workspaces, and CI gating.
Run npx @mcpjam/inspector@latest, open the localhost link it prints, and connect your server.
