v2.0.0

Compare Source

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

v1.0.2

v1.0.0

Compare Source

Versioning Note

Since this should be the last release of the classic MCP Inspector, it is finally being promoted to 1.0.0, primarily so that it can be referred to as the V1 implementation. It fixes outstanding security warnings and includes a couple of bug fixes.

Along with the release of the the upcoming 2026-07-28 MCP specification, we will be publishing an entirely new Inspector with a completely different codebase. The V2 web-based inspector client, the CLI, and a new TUI — all of which have a shared code architecture — will all ship as a single npm package. The V1 Inspector package will be officially deprecated at that time, and no further work will be done on that line.
