What the reviewer found

Local-development counterpart of the canary-setup skill, pointing the MCP server at localhost:3000. The flagged .env/.mcp.json reads only check for an existing key/config before writing the user-supplied key, and it adds .mcp.json to .gitignore. Entirely local.

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.
