Subsequent Pi MCP use can launch the registered executable with access inherited from the agent environment. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.22 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Automatic installation modifies Pi's global MCP configuration to register a package-controlled executable. This establishes an unconsented mutation of a foreign AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-30T14:30:40.003Z - **Finished:** 2026-09-30T14:32:06.661Z - **Download time:** 1815 ms - **Static scan time:** 37 ms - **AI review time:** 84805 ms - **Total time:** 86658 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:** Automatic installation modifies Pi's global MCP configuration to register a package-controlled executable. This establishes an unconsented mutation of a foreign AI-agent control surface. - **Trigger:** npm postinstall, when the google-services MCP entry is absent. - **Impact:** Subsequent Pi MCP use can launch the registered executable with access inherited from the agent environment. - **Evidence paths:** package.json, install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T14:32:06.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install.js installs the executable and writes a server registration into the user's Pi agent configuration without requesting consent. - **Attack narrative:** Installing the package automatically invokes install.js. The installer places its executable in the user's local binary directory and adds a server command to Pi's global MCP configuration when that entry is absent. No explicit setup command or consent gate precedes this configuration write. The foreign agent configuration mutation independently meets the supplied blocking policy; executable internals and credential theft are not needed to establish that behavior. - **Rationale:** Inspected source proves an automatic, unconsented postinstall write to Pi's global agent control surface. Under the supplied policy, this warrants blocking despite guards that preserve existing entries and invalid configuration files. - **Files touched:** .pi/agent/mcp.json, .local/bin/pi-google-services ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs install.js during postinstall., install.js targets the user's global Pi agent MCP configuration., The installer registers its executable with the serve argument and writes the MCP configuration without a consent gate., The postinstall entrypoint calls binary installation and MCP registration automatically. - **Evidence against:** The installer preserves an existing google-services entry and refuses to overwrite invalid JSON., No credential exfiltration was established; the bundled executable could not be fully inspected. ## Affected versions and remediation This report applies to pi-google-services@0.1.22. - Avoid installing pi-google-services@0.1.22. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
