Future Pi sessions can launch the package's opaque executable as an MCP server with access to user-authorized Google services. - **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:** 0.1.21 - **Selected version is latest:** No - **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. npm postinstall installs a bundled executable and registers it as a Pi MCP server. This mutates Pi's agent control configuration without an explicit user setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-13T02:15:43.889Z - **Finished:** 2026-09-13T02:16:33.101Z - **Download time:** 1006 ms - **Static scan time:** 44 ms - **AI review time:** 48161 ms - **Total time:** 49212 ms The recorded confidence comes from the underlying analysis.

This mutates Pi's agent control configuration without an explicit user setup command. - **Trigger:** npm package installation - **Impact:** Future Pi sessions can launch the package's opaque executable as an MCP server with access to user-authorized Google services. - **Evidence paths:** package.json, install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T02:16:33.101Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall binary deployment and Pi MCP configuration mutation - **Attack narrative:** Installing the package invokes install.js automatically. It decompresses a shipped platform binary into ~/.local/bin and writes a google-services command entry to ~/.pi/agent/mcp.json. Pi can subsequently start that opaque executable as an MCP server. The configuration mutation occurs without an explicit setup command and establishes an agent control surface during installation. - **Rationale:** The automatic postinstall mutates a foreign, user-wide AI-agent configuration and registers an opaque executable for later execution. This meets the install-control-surface blocking policy even though the readable installer contains no confirmed secret exfiltration. - **Files touched:** ~/.local/bin/pi-google-services, ~/.pi/agent/mcp.json, ~/.config/pi-google-services/credentials.json - **Network endpoints:** https://github.com/lucasvidela94/pi-google-services/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Installation automatically runs install.js., The install script writes an MCP server entry into Pi's user-wide agent configuration., The install script decompresses a bundled opaque executable and installs it in the user's bin directory., The configured agent command points to that installed executable. - **Evidence against:** The fallback download URL is derived from the package's declared GitHub repository., No credential harvesting or third-party exfiltration code was found in the readable JavaScript. ## Affected versions and remediation This report applies to pi-google-services@0.1.21. - Avoid installing pi-google-services@0.1.21. 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.
