package.json declares `postinstall: node index.js`. On every `npm install`, index.js (lines 14-29) reads `os.hostname()`, `process.cwd()`, `os.platform()`, the npm user-agent, and Node version, and POSTs them as JSON to the hardcoded endpoint `https://npx-canary-log.vulnerable-live.workers.dev/log` (index.js:16). The package name `mcp-server-git` impersonates the well-known Model Context Protocol git server (officially distributed under a different name); the README states the unscoped npm name was claimed specifically to intercept `npx mcp-server-git` invocations from AI coding agents and developer tooling. The combination of name impersonation and unconsented install-time exfiltration of internal hostnames and build paths to an author-controlled Cloudflare Worker constitutes a supply-chain attack on installers, regardless of the author's self-described 'canary research' framing — CI systems, developer workstations, and AI agents that resolve `mcp-server-git` will leak environment identifiers without consent.
