It ships as a single package, @modelcontextprotocol/inspector , that provides three ways to inspect a server: - Web — a Vite + React + Mantine single-page app with a Node backend. - CLI — a scriptable command-line client for automation, CI, and fast agent feedback loops. - TUI — an interactive terminal UI built with Ink. All three run through one global mcp-inspector binary: Upgrading from v1? Read the v1 → v2 migration guide — CLI flags, the new --config vs. --catalog split, the Node engine bump, and what no longer ships. Repo status. This is the v2 line of the Inspector. Active development happens on v2/main (the develop branch — all v2 PRs target it), which is merged into main at milestone releases; main is the default branch and holds the latest released v2, published to the npm latest tag. The legacy v1 line lives on v1/main — security fixes only, published straight from that branch to the npm v1-latest tag ( npx @modelcontextprotocol/inspector@v1-latest ). See AGENTS.md for branch/board conventions. Project layout v2 is not an npm workspace. Each client under clients/ keeps its own package.json and node modules ; shared code lives in core/ and is consumed via a @inspector/core build-time alias (no package.json of its own). A single npm install at the root cascades installs into every client (see Setup). Each client has its own README with client-specific detail: web · cli · tui · launche","default_branch":null,"files":null,"tree":[],"storefront":"/r/modelcontextprotocol","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/modelcontextprotocol/inspector/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
