AI Summary

A patch release that fixes a regression in the default command execution where the new `mcpdo` binary conflicted with the expected `launcher` binary, restoring the `npx @modelcontextprotocol/inspector` alias functionality.

Key Highlights

  • Restored the `npx @modelcontextprotocol/inspector` alias to point to the `launcher` binary
  • Documentation update clarifying usage of the new `mcpdo` client

Full Release Notes

## Why The Patch?
The addition of the new `mcpdo` client threw a curveball into the default `npx @modelcontextprotocol/inspector@latest` method of running the inspector, because there were now two binaries to run, the `launcher` (used by the other clients) and `mcpdo`. This quick follow-up patch restores sanity so that command works again. Instructions for launching new `mcpdo` client are on `README.md`.
