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 modifies detected agent configuration and may add Claude Code hooks, creating a guarded agent integration lifecycle risk. The inspected behavior is package-owned setup, with no evidence of a concrete attack that warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-11T11:37:06.720Z - **Finished:** 2026-10-11T11:37:50.122Z - **Download time:** 508 ms - **Static scan time:** 140 ms - **AI review time:** 42753 ms - **Total time:** 43402 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 can add pintumcp configuration to detected agent tools and hooks to Claude Code settings. This is package-owned agent integration, but its configuration changes occur during installation without a separate setup command. - **Trigger:** Installing the package through npm, which runs its postinstall hook. - **Impact:** Agent configuration changes can enable pintumcp integrations after installation; no credential theft or unrelated payload execution was identified in the inspected source. - **Evidence paths:** package.json, install.js, bin/pintumcp.js, lib/detect.js, lib/configure.js, lib/hooks.js - **Review source:** ai\_review - **Reviewed:** 2026-10-11T11:37:50.122Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the CLI install command, which detects agent tools, writes pintumcp MCP configuration, and may add Claude Code event hooks. - **Rationale:** The postinstall hook automatically modifies detected agent configuration and may add Claude Code hooks, creating a guarded agent integration lifecycle risk. The inspected behavior is package-owned setup, with no evidence of a concrete attack that warrants blocking publication. - **Files touched:** package.json, install.js, bin/pintumcp.js, lib/detect.js, lib/configure.js, lib/hooks.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs an install.js script during postinstall, which launches the CLI install command., The install command detects available coding tools and configures the package for detected tools., When a Claude Code settings directory exists, setup adds pintumcp hooks for several events., The detector targets multiple agent and editor configurations, including Claude, Codex, OpenCode, and VS Code. - **Evidence against:** The configuration entries and hooks point to pintumcp’s own server and hook files., Setup is limited to detected tools or existing agent configuration locations; inspected code showed no credential collection or network transmission. ## Affected versions and remediation This report applies to pintumcp@1.2.12. - Review the evidence and your use of pintumcp@1.2.12 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.
