The consumer project gains active agent behavior and a later remote MCP execution channel without an explicit setup 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:** 2.5.102 - **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. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies multiple project AI-agent control surfaces. It installs rules, skills, an active agent, and MCP configurations including an unpinned npx command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T04:49:42.363Z - **Finished:** 2026-09-14T04:50:47.619Z - **Download time:** 1027 ms - **Static scan time:** 648 ms - **AI review time:** 63580 ms - **Total time:** 65256 ms The recorded confidence comes from the underlying analysis.

It installs rules, skills, an active agent, and MCP configurations including an unpinned npx command. - **Trigger:** npm postinstall when this package is installed as a project dependency. - **Impact:** The consumer project gains active agent behavior and a later remote MCP execution channel without an explicit setup command. - **Evidence paths:** package.json, bin/postinstall.js, lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T04:50:47.619Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-platform AI-agent configuration and MCP registration. - **Attack narrative:** The postinstall hook calls the installer with JoyCode, Cursor, WorkBuddy, agent, and version features enabled. The installer writes agent rules and skills into the consumer project, activates a JoyCode agent, and alters MCP configuration for all three platforms. One registered MCP command is npx -y @playwright/mcp@latest, so a future agent launch can fetch and execute an unpinned remote package. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** This package performs unconsented postinstall modification of multiple foreign AI-agent control surfaces and installs an unpinned remote MCP command. That is concrete install-hook abuse under the stated policy. - **Files touched:** .joycode/agent.json, .joycode/mcp.json, .cursor/mcp.json, .workbuddy/mcp.json, .joycode/skills/, .cursor/skills/, .workbuddy/skills/, mcp/proto-version-server.js, mcp/line-repos-server.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package has an automatic postinstall hook., Postinstall invokes the installer with all supported AI-agent platforms, agent creation, and version-service setup enabled., The installer writes skills and rules into .joycode, .cursor, and .workbuddy, and registers MCP servers in their configuration files., It registers an MCP server that runs npx -y @playwright/mcp@latest, creating a future unpinned remote execution channel., It creates an active JoyCode agent entry without an explicit user command. - **Evidence against:** No credential harvesting or secret exfiltration was found in the inspected install path., The local prototype service binds only to 127.0.0.1., Online publishing requires a user-supplied deployment URL. ## Affected versions and remediation This report applies to @deppon/pm-toolkit@2.5.102. - Avoid installing @deppon/pm-toolkit@2.5.102. 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.
