Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Installation drops a bundled native executable into the user's local bin directory and registers it as a Pi MCP server. The payload itself is compressed native code rather than reviewable source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-08T22:07:48.726Z - **Finished:** 2026-09-08T22:09:00.607Z - **Download time:** 1016 ms - **Static scan time:** 52 ms - **AI review time:** 70811 ms - **Total time:** 71881 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation drops a bundled native executable into the user's local bin directory and registers it as a Pi MCP server. The payload itself is compressed native code rather than reviewable source. - **Trigger:** npm postinstall - **Impact:** A newly installed package gains a persistent AI-agent tool entrypoint with behavior that cannot be fully audited from the included source. - **Evidence paths:** package.json, install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T22:09:00.607Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic native binary deployment and Pi MCP configuration mutation. - **Rationale:** This is a first-party, package-specific agent-extension installer rather than confirmed malicious behavior, but it automatically deploys opaque native code and mutates an AI-agent control surface. The residual lifecycle risk warrants a warning. - **Files touched:** bin/pi-google-services-linux-amd64.gz, bin/pi-google-services-linux-arm64.gz, bin/pi-google-services-darwin-arm64.gz, ~/.local/bin/pi-google-services, ~/.config/pi-google-services/credentials.json, ~/.pi/agent/mcp.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest automatically runs install.js after installation., The installer decompresses a bundled native executable and writes it to the user's local bin directory., The installer automatically adds that executable as a Pi MCP server in the user's agent configuration., The native payload is shipped only as compressed binaries, so its complete behavior cannot be established from source files in this package. - **Evidence against:** The configuration change is limited to one named google-services MCP entry., The installer refuses to overwrite invalid Pi configuration., The network download is only a fallback when the bundled asset is absent., No self-dependency or source-level credential harvesting or exfiltration was found. ## Affected versions and remediation This report applies to pi-google-services@0.1.20. - Review the evidence and your use of pi-google-services@0.1.20 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
