The v2 Inspector is now the default release.

npx @modelcontextprotocol/inspector          # web UI
npx @modelcontextprotocol/inspector --cli    # CLI
npx @modelcontextprotocol/inspector --tui    # TUI

What's new

v2 ships as a single package with three clients — a Vite + React + Mantine web UI, a scriptable CLI, and an Ink-based TUI — over a shared @inspector/core runtime, so all three behave identically.

Upgrading from v1

  • Node >= 22.19.0 is now required (was >= 22.7.5).
  • CLI flags changed substantially. In particular --config now means a read-only session file; --catalog is the writable server list. See MCP server configuration.
  • The v1 sub-packages (inspector-client, inspector-server, inspector-cli) are deprecated and not part of v2 — v2 publishes a single package.

v1

v1 is deprecated and receives security fixes only, published under the v1-latest tag:

npm i @modelcontextprotocol/inspector@v1-latest
