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:** 0.4.1 - **Selected version is latest:** No - **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 package automatically mutates agent configuration during postinstall to enable its own MCP server. This is a concrete first-party agent integration capability, but the inspected code does not establish a broader hijack or other attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T23:02:46.469Z - **Finished:** 2026-10-09T23:03:49.999Z - **Download time:** 1282 ms - **Static scan time:** 797 ms - **AI review time:** 61450 ms - **Total time:** 63530 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:** An eligible npm install automatically adds this package’s MCP server to supported agent configuration. This is a first-party integration setup; no broader control-surface mutation or confirmed attack was identified. - **Trigger:** An eligible global or package-root npm install runs the postinstall hook, unless the MCP setup skip variable is set. - **Impact:** The agent can launch this package’s MCP server after installation; the automatic configuration change occurs without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/src/cli/install-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T23:03:49.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook invokes the package’s MCP installer, which writes its own named server entry to Claude or Codex configuration. - **Rationale:** The package automatically mutates agent configuration during postinstall to enable its own MCP server. This is a concrete first-party agent integration capability, but the inspected code does not establish a broader hijack or other attack behavior. - **Files touched:** ~/.codex/config.toml, Claude Desktop MCP configuration ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json defines an npm postinstall hook that loads scripts/postinstall.cjs., The hook skips transitive installs and can be disabled with PAAT\_SKIP\_INSTALL\_MCP=1, but eligible installs run the MCP installer automatically., The installer targets this product’s MCP configuration entry and writes it to the existing configuration., The requested Codex configuration location is ~/.codex/config.toml. - **Evidence against:** The integration registers the package’s own MCP server name and command, rather than changing unrelated agent settings., The installer backs up existing configuration and preserves other MCP entries. ## Affected versions and remediation This report applies to port-authority-agent-terminal-mcp@0.4.1. - Review the evidence and your use of port-authority-agent-terminal-mcp@0.4.1 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.
