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:** 1.2.1 - **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 postinstall hook automatically configures the package's own MCP integration in detected AI tools, creating an agent extension lifecycle risk. The inspected behavior supports a warning, while no concrete malicious chain was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-09T05:00:51.536Z - **Finished:** 2026-10-09T05:01:17.674Z - **Download time:** 771 ms - **Static scan time:** 81 ms - **AI review time:** 25285 ms - **Total time:** 26138 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 postinstall hook automatically sets up pintumcp and can add its MCP server to detected AI tool settings. This is a real agent configuration change, but the inspected behavior is first-party setup for the package's stated integration. - **Trigger:** Installing the package with npm runs its postinstall hook. - **Impact:** Detected tools may launch the package's Python server; no confirmed credential exposure or other malicious effect was established. - **Evidence paths:** package.json, install.js, bin/pintumcp.js, lib/configure.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:01:17.674Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs the install command, which detects supported tools and writes a pintumcp MCP entry to their configuration. - **Rationale:** The postinstall hook automatically configures the package's own MCP integration in detected AI tools, creating an agent extension lifecycle risk. The inspected behavior supports a warning, while no concrete malicious chain was established. - **Files touched:** package.json, install.js, bin/pintumcp.js, lib/configure.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs install.js from its postinstall hook., install.js automatically invokes the package's install command., The install command detects supported AI tools and configures the package's own MCP server in their settings., The installer creates a Python virtual environment and installs dependencies. - **Evidence against:** The inspected setup adds a named pintumcp integration to detected tools; no credential collection or external endpoint was found in the inspected source. ## Affected versions and remediation This report applies to pintumcp@1.2.1. - Review the evidence and your use of pintumcp@1.2.1 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.
