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:** 1.2.18 - **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 lifecycle hook automatically configures package-owned agent integrations without a separate consent step. This is an agent extension lifecycle risk; the inspected sources do not establish a concrete malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-13T22:25:05.264Z - **Finished:** 2026-10-13T22:29:30.760Z - **Download time:** 516 ms - **Static scan time:** 108 ms - **AI review time:** 264871 ms - **Total time:** 265496 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 runs setup that adds this package’s agent integrations when matching configuration directories exist. - **Trigger:** Installing the package through npm, which runs its postinstall hook. - **Impact:** Agent configuration changes and later hook activity may be unexpected; the inspected evidence supports a warning for automatic first-party extension setup, not a confirmed attack. - **Evidence paths:** package.json, install.js, bin/pintumcp.js, lib/configure.js, lib/hooks.js, python/hook.py - **Review source:** ai\_review - **Reviewed:** 2026-10-13T22:29:30.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The setup writes the package’s MCP entry and installs its OpenCode plugin and Claude Code hooks without an additional consent prompt. - **Rationale:** The lifecycle hook automatically configures package-owned agent integrations without a separate consent step. This is an agent extension lifecycle risk; the inspected sources do not establish a concrete malicious attack. - **Files touched:** package.json, install.js, bin/pintumcp.js, lib/configure.js, lib/hooks.js, python/hook.py ### 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 as a postinstall hook., install.js launches the CLI install command during postinstall., The CLI defaults to install and configures detected tools, then installs its OpenCode plugin and Claude Code hooks when their directories exist., The specified Claude settings location calls addHooks; the hook helper registers package-owned commands for five Claude Code events., The Claude hook uses prompt text, limited to 80 characters, in its status message. - **Evidence against:** The integrations configure this package’s own MCP entry and package-owned plugin or hooks; inspected code did not establish a write to unrelated agent settings or a remote prompt collector. ## Affected versions and remediation This report applies to pintumcp@1.2.18. - Review the evidence and your use of pintumcp@1.2.18 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.
