Consumer AI-agent clients may load package-provided instructions and execute the configured npx latest MCP command; project files are modified during installation. - **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:** 2.5.105 - **Selected version is latest:** Yes - **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 the consuming project's AI-agent configuration and project metadata. It registers local MCP tools and an npx latest Playwright MCP command without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T21:51:31.702Z - **Finished:** 2026-09-11T21:52:36.476Z - **Download time:** 1009 ms - **Static scan time:** 764 ms - **AI review time:** 62999 ms - **Total time:** 64774 ms The recorded confidence comes from the underlying analysis.

It registers local MCP tools and an npx latest Playwright MCP command without an explicit setup command. - **Trigger:** npm install of the package as a project dependency. - **Impact:** Consumer AI-agent clients may load package-provided instructions and execute the configured npx latest MCP command; project files are modified during installation. - **Evidence paths:** package.json, bin/postinstall.js, lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T21:52:36.476Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall invokes a broad project synchronizer that writes agent files, MCP settings, scripts, and copied assets. - **Attack narrative:** The postinstall hook detects a normal project dependency installation and immediately calls the installer with all AI-agent platforms and agent features enabled. The installer populates JoyCode, Cursor, and WorkBuddy directories, registers MCP entries, and configures one entry as \`npx -y @playwright/mcp@latest\`. It also changes the consumer package.json and copies executable tooling. These broad, unconsented install-time modifications affect foreign AI-agent control surfaces and can cause later agent startup to fetch and run a moving external package. - **Rationale:** This is concrete unconsented postinstall mutation of multiple foreign AI-agent control surfaces, including a remote latest npx MCP command. The guard against global installs does not limit the behavior for ordinary consumer-project installation. - **Files touched:** .joycode/mcp.json, .cursor/mcp.json, .workbuddy/mcp.json, .joycode/agent.json, package.json, scripts/proto-version.js, mcp/proto-version-server.js - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall hook., Postinstall runs the installer against the consuming project with JoyCode, Cursor, WorkBuddy, agent, and version features all enabled., The installer writes MCP registrations into three AI-agent configuration directories and adds an npx command pinned to latest., The installer overwrites the consumer package.json scripts and adds itself as a development dependency. - **Evidence against:** The postinstall hook skips global or npx-style installs unless this package is installed under the consumer project node\_modules., The inspected MCP servers are local stdio tools for prototype versioning and local code search; no credential collection or secret exfiltration was found., The flagged Python test file is an ordinary unittest suite, not a hidden payload. ## Affected versions and remediation This report applies to @deppon/pm-toolkit@2.5.105. - Avoid installing @deppon/pm-toolkit@2.5.105. 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.
