pi-mcp-extension@1.15.2
VERIFIED· install onlyPublisher claims: "Full-featured, lightweight MCP extension for the Pi coding agent: stdio, SSE & Streamable HTTP transports, OAuth 2.1 (PKCE + DCR), lazy/eager lifecycles — minimal dependencies, zero bloat." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
Is [email protected] safe to install?
KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 88/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

/** `https://user:[email protected]/mcp` — userinfo credentials in a URL. */Fix: Stop enumerating or reading credential locations; take secrets from a declared environment variable the user sets on purpose.// WHY: Windows has no `/proc` or `ps`, and the portable tree kill (`taskkill /T`)Fix: Build commands from fixed arguments; do not interpolate untrusted strings into a shell.kill: deps.kill ?? defaultDeps.kill,Fix: Build commands from fixed arguments; do not interpolate untrusted strings into a shell.// WHY: Something removed `<agentDir>/logs` between the mkdir and the chmodFix: Request the narrowest permission that works; replace wildcards with the exact paths or hosts.Cost to the agent
Tokens estimated at four characters each. Skills load their instruction text when triggered; the figure is what that costs.
