pi-mcp-extension@1.14.4

VERIFIED· install only

Publisher 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.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-08 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.

Static findings

MEDIUM
File permission modification commandsrc/debug-log.ts:170 · File permission modification command — agent changes file ownership/permissions// 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.
AST05
HIGH
URL with embedded credentialssrc/debug-log-format.ts:113 · URL with embedded credentials — may be phishing or credential leaking/** `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.
AST07
MEDIUM
Process kill commandsrc/stdio-process.ts:372 · Process kill command — agent can terminate processes// 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.
