Consumer .env, data, documentation links, Cursor MCP configuration, and Codex configuration can be changed; future AI-agent sessions can start the package's MCP 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:** 0.6.6 - **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 changes consumer-project files and existing user AI-agent configuration. It registers a Ghostcrab MCP server in Cursor and Codex configuration without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T00:31:44.207Z - **Finished:** 2026-09-14T00:32:51.034Z - **Download time:** 1030 ms - **Static scan time:** 2058 ms - **AI review time:** 63737 ms - **Total time:** 66827 ms The recorded confidence comes from the underlying analysis.

It registers a Ghostcrab MCP server in Cursor and Codex configuration without an explicit setup command. - **Trigger:** npm install runs postinstall when the native backend is available. - **Impact:** Consumer .env, data, documentation links, Cursor MCP configuration, and Codex configuration can be changed; future AI-agent sessions can start the package's MCP server. - **Evidence paths:** package.json, bin/lib/postinstall-prebuilds.mjs, bin/lib/postinstall-host-bootstrap.mjs, bin/lib/install-upgrade.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-14T00:32:51.034Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall bootstrap and automatic MCP configuration rewrite. - **Attack narrative:** A registry install triggers postinstall. The script creates consumer-project files and symlinks, then automatically runs an upgrade with configuration cleanup enabled. That upgrade rewrites existing Cursor and Codex configuration, adding a Ghostcrab MCP server that invokes the package CLI. This is an unconsented install-time mutation of foreign AI-agent control surfaces. - **Rationale:** The package performs automatic postinstall rewrites of user Cursor and Codex MCP settings, alongside broad consumer-project mutation. This meets the blocking policy for unconsented lifecycle mutation of AI-agent control surfaces. - **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 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall script., Postinstall mutates the consumer project by creating .env and data and linking package content., Postinstall automatically invokes an upgrade with config cleanup enabled., The upgrade rewrites existing Cursor and Codex MCP configuration to register this package's server. - **Evidence against:** The observed network checks are limited to a temporary localhost backend; no outbound exfiltration endpoint was established. ## Affected versions and remediation This report applies to @mindflight/ghostcrab-personal-mcp@0.6.6. - Avoid installing @mindflight/ghostcrab-personal-mcp@0.6.6. 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.
