Consumer project files and broad AI-agent control surfaces can be altered, causing Cursor or Codex to launch the package server. - **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:** 0.6.8 - **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. Installing the package runs a postinstall script that modifies the consumer project and registers this package as an MCP server in existing Cursor and Codex configurations. The registration makes the package command available to those agent clients without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T18:43:05.769Z - **Finished:** 2026-09-07T18:44:09.732Z - **Download time:** 1013 ms - **Static scan time:** 3284 ms - **AI review time:** 59664 ms - **Total time:** 63963 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:** Installing the package runs a postinstall script that modifies the consumer project and registers this package as an MCP server in existing Cursor and Codex configurations. The registration makes the package command available to those agent clients without an explicit setup command. - **Trigger:** npm installation when the native backend is available and opt-out environment variables are absent. - **Impact:** Consumer project files and broad AI-agent control surfaces can be altered, causing Cursor or Codex to launch the package server. - **Evidence paths:** bin/lib/postinstall-prebuilds.mjs, bin/lib/install-upgrade.mjs, bin/lib/postinstall-host-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T18:44:09.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall bootstrap and automatic MCP configuration rewrite. - **Attack narrative:** On npm install, the lifecycle hook bootstraps files and links in the consuming project. When its native backend is available, it automatically runs an upgrade routine with configuration cleanup enabled. That routine replaces the package's MCP entries in Cursor and Codex configuration and adds a server command pointing at the installed package. This is an unconsented install-time mutation of external AI-agent control surfaces. - **Rationale:** The automatic postinstall chain writes consumer-project files and registers an MCP server in Cursor and Codex configuration. This is concrete install-hook abuse even though the inspected path did not show external exfiltration. - **Files touched:** consumer project/.env, consumer project/data, consumer project/README.md, consumer project/INSTALL.md, consumer project/Licence.md, consumer project/ghostcrab-skills, ~/.cursor/mcp.json, ~/.cursor/mcp.json.bak, ~/.codex/config.toml, ~/.codex/config.toml.bak, ~/.ghostcrab/bin/gcp ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., Postinstall runs host-project bootstrap before native preparation., Postinstall automatically runs upgrade with configuration cleanup enabled., Upgrade rewrites Cursor MCP configuration to launch this package., Upgrade rewrites Codex configuration and the host bootstrap writes into the consumer project. - **Evidence against:** No external network endpoint or credential exfiltration was confirmed in the inspected lifecycle path., The package does not runtime-depend on its own package name; listed platform packages are distinct optional dependencies. ## Affected versions and remediation This report applies to @mindflight/ghostcrab-personal-mcp@0.6.8. - Avoid installing @mindflight/ghostcrab-personal-mcp@0.6.8. 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.
