mcp-server-sentry — Security Research Canary

This package is part of an authorized bug bounty research project investigating npx confusion — a supply chain attack vector where unclaimed npm package names matching common binary references can be squatted.

What this package does

On install or execution, it sends minimal telemetry to a logging endpoint:

• Timestamp, hostname, working directory, npm user-agent, platform
• Nothing sensitive — no environment variables, file contents, tokens, or keys

Why it exists

The unscoped package name mcp-server-sentry was unclaimed on npm. The official equivalent (if any) uses a scoped name. AI coding agents and developer tooling commonly invoke npx mcp-server-sentry, which resolves to whatever package owns this name on the npm registry. This canary proves that real traffic reaches this name.

Disclosure

This is security research. If you received this package unintentionally, it means an AI agent or automated tool resolved mcp-server-sentry via npx and the package was publicly available. No malicious action has been taken.
