What the reviewer found

Sets up a project-local MCP server pointing at the vendor's own canary API (canary.magnet.run); it reads .env/.mcp.json only to check for an existing key before writing one the user supplies interactively, and adds .mcp.json to .gitignore. Nothing leaves the user's machine.

How this review was made

Sonnet 5 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
