Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.7.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall automatically adds or refreshes this package's MCP server entry in existing user-level Cursor and Codex configuration. The changes are scoped to Ghostcrab entries, so the evidence supports a warning for first-party agent integration rather than a broad control hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-14T13:10:22.940Z - **Finished:** 2026-10-14T13:12:44.039Z - **Download time:** 1285 ms - **Static scan time:** 2320 ms - **AI review time:** 137493 ms - **Total time:** 141099 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:** The install hook can update existing user-level Cursor and Codex MCP configuration with this package's server entry. This is a first-party agent integration performed during installation, supporting a lifecycle-risk warning. - **Trigger:** Package installation, after a successful prebuild, unless the upgrade step is skipped by its environment setting. - **Impact:** The IDE configuration gains an automatic registration for this package's MCP server. The inspected path does not change unrelated MCP entries or grant broad permissions. - **Evidence paths:** package.json, bin/lib/postinstall-prebuilds.mjs, bin/lib/install-upgrade.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-14T13:12:44.039Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs the upgrade routine, which replaces matching Ghostcrab entries in existing Cursor and Codex MCP configuration with an entry that launches this package. - **Rationale:** The postinstall automatically adds or refreshes this package's MCP server entry in existing user-level Cursor and Codex configuration. The changes are scoped to Ghostcrab entries, so the evidence supports a warning for first-party agent integration rather than a broad control hijack. - **Files touched:** ~/.cursor/mcp.json, ~/.codex/config.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall hook. After a successful prebuild, the hook calls the upgrade routine with configuration cleanup enabled and dry-run disabled., The upgrade routine refreshes Cursor and Codex MCP configuration during its normal run., For an existing Cursor MCP file, the routine removes Ghostcrab-related entries and adds this package's own server entry; it leaves a missing file alone., For Codex, the routine filters Ghostcrab MCP sections and writes the updated configuration with a backup., The other flagged locations are setup helpers for skill paths, MCP registration, and permissions, separate from the postinstall upgrade path. - **Evidence against:** The automatic changes are limited to this package's Ghostcrab MCP entries; the inspected code does not grant broad agent permissions or rewrite unrelated MCP entries., The postinstall integration runs only after a successful prebuild and can be skipped with an environment setting. ## Affected versions and remediation This report applies to @mindflight/ghostcrab-personal-mcp@0.7.4. - Review the evidence and your use of @mindflight/ghostcrab-personal-mcp@0.7.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
