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:** 1.2.2 - **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 automatic setup changes detected AI tool configurations, but the written entry launches this package's own MCP server. This is first-party extension setup and supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T05:16:47.962Z - **Finished:** 2026-10-09T05:17:07.437Z - **Download time:** 778 ms - **Static scan time:** 83 ms - **AI review time:** 18613 ms - **Total time:** 19475 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:** Installation automatically adds this package's MCP server to detected AI tool configurations. The inspected behavior is first-party extension setup, with no confirmed malicious attack surface. - **Trigger:** npm postinstall runs the install command. - **Impact:** Detected tools are configured to launch pintumcp as an MCP server. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:17:07.437Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install command detects supported AI tools and writes a pintumcp server entry containing this package's Python executable and server path. - **Rationale:** The automatic setup changes detected AI tool configurations, but the written entry launches this package's own MCP server. This is first-party extension setup and supports a warning rather than a block. - **Files touched:** package.json, install.js, bin/pintumcp.js, lib/configure.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook automatically runs the package's install command., Install configures pintumcp as an MCP server in detected AI tool configurations., The configured entry launches this package's own Python server; this is first-party extension setup. - **Evidence against:** The source shows configuration writes limited to a pintumcp MCP entry in detected tool configs., A source search found no HTTP references in the Python directory. ## Affected versions and remediation This report applies to pintumcp@1.2.2. - Review the evidence and your use of pintumcp@1.2.2 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.
