The package gains an automatically registered MCP launch entry in existing agent clients and changes consumer-project contents without an explicit setup command. - **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:** 0.6.9 - **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 automatically modifies existing global Cursor and Codex MCP configuration to register and launch GhostCrab. It also modifies the consuming project by creating files and symlinks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T07:51:32.160Z - **Finished:** 2026-09-14T07:52:50.805Z - **Download time:** 763 ms - **Static scan time:** 2585 ms - **AI review time:** 75295 ms - **Total time:** 78645 ms The recorded confidence comes from the underlying analysis.

It also modifies the consuming project by creating files and symlinks. - **Trigger:** npm postinstall during package installation - **Impact:** The package gains an automatically registered MCP launch entry in existing agent clients and changes consumer-project contents without an explicit setup command. - **Evidence paths:** package.json, bin/lib/postinstall-prebuilds.mjs, bin/lib/install-upgrade.mjs, bin/lib/postinstall-host-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T07:52:50.805Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic rewriting of AI-agent configuration and consumer-project bootstrap - **Attack narrative:** On npm installation, the postinstall script calls the upgrade routine without dry-run mode and enables configuration cleanup. The routine rewrites existing global Cursor and Codex MCP configuration to add this package as a launched MCP server. Separately, postinstall creates a consumer .env and data directory and adds documentation and skill symlinks. These are unconsented install-time mutations of AI-agent control surfaces and the consuming project. - **Rationale:** This is malicious under the install-control-surface policy because a postinstall hook automatically rewrites existing global Cursor and Codex agent configuration. The additional consumer-project mutations confirm broad automatic install-time modification. - **Files touched:** ~/.cursor/mcp.json, ~/.cursor/mcp.json.bak, ~/.codex/config.toml, ~/.codex/config.toml.bak, consumer-project/.env, consumer-project/data, consumer-project/README.md, consumer-project/INSTALL.md, consumer-project/Licence.md, consumer-project/ghostcrab-skills ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall script automatically., Postinstall automatically invokes an upgrade routine with configuration cleanup enabled., That routine rewrites existing global Cursor and Codex MCP configuration to launch this package., Postinstall also creates consumer-project files and links without an explicit command. - **Evidence against:** No runtime dependency on this package's own name was found., The reviewed configuration writes point to the package's own MCP server and no secret exfiltration endpoint was identified. ## Affected versions and remediation This report applies to @mindflight/ghostcrab-personal-mcp@0.6.9. - Avoid installing @mindflight/ghostcrab-personal-mcp@0.6.9. 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.
