Agent applications may load the package's server without a separate explicit configuration command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.2.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall changes existing AI-agent configuration files so they can load this package's server. This meets the install-time control-surface mutation block criterion. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-08T18:06:57.670Z - **Finished:** 2026-10-08T18:07:27.081Z - **Download time:** 503 ms - **Static scan time:** 67 ms - **AI review time:** 28840 ms - **Total time:** 29411 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 npm postinstall automatically adds this package's MCP server to detected agent settings files. - **Trigger:** Installing the package through npm, which runs its postinstall script. - **Impact:** Agent applications may load the package's server without a separate explicit configuration command. - **Evidence paths:** package.json, install.js, bin/pintumcp.js, lib/detect.js, lib/configure.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T18:07:27.081Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer detects supported agent configuration files and writes a pintumcp server entry into each detected configuration. - **Attack narrative:** During npm installation, the postinstall script launches the CLI's install command. That command detects existing agent configuration files and adds a server entry pointing to this package's Python notification service. This is an unconsented install-time mutation of foreign agent control settings. - **Rationale:** The automatic postinstall changes existing AI-agent configuration files so they can load this package's server. This meets the install-time control-surface mutation block criterion. - **Files touched:** package.json, install.js, bin/pintumcp.js, lib/detect.js, lib/configure.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json starts a postinstall script that runs install.js., install.js automatically runs the CLI install command during postinstall., The install command configures every detected tool, including existing agent settings under the user's home directory., The configuration code writes updated settings files; the added MCP server runs this package's Python notification server. - **Evidence against:** The configured server exposes desktop notification and sound tools; inspected source shows no credential collection or network endpoint. ## Affected versions and remediation This report applies to pintumcp@1.2.0. - Avoid installing pintumcp@1.2.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
