It changes a broad AI-agent control surface without an explicit setup command and can cause later remote MCP connections or npx execution. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.1.99 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies the consumer project’s AI-agent, editor, GitHub, and MCP configuration. It also installs MCP endpoints and a command that resolves a latest-version package at later agent use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-05T01:33:32.461Z - **Finished:** 2026-09-05T01:34:31.057Z - **Download time:** 503 ms - **Static scan time:** 733 ms - **AI review time:** 57360 ms - **Total time:** 58596 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies the consumer project’s AI-agent, editor, GitHub, and MCP configuration. It also installs MCP endpoints and a command that resolves a latest-version package at later agent use. - **Trigger:** npm installation runs postinstall automatically. - **Impact:** It changes a broad AI-agent control surface without an explicit setup command and can cause later remote MCP connections or npx execution. - **Evidence paths:** package.json, bin/install.js, bin/folder-mappings.js, mcp.json, vscode/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-09-05T01:34:31.057Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies package-controlled agent configuration into the current project - **Attack narrative:** A normal npm install invokes bin/install.js through postinstall. The installer copies package-supplied directories and configuration into the consumer project, including several AI-agent control locations and .mcp.json. The added MCP configuration includes two remote services and an npx shadcn@latest command, while VS Code settings enable agent behavior and MCP discovery for other tools. This is unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The package has an automatic lifecycle hook that writes broad foreign AI-agent and editor configuration into the consuming project. The installed configuration adds remote MCP access and deferred npx execution, so this is concrete install-hook abuse rather than a user-invoked setup action. - **Files touched:** \_bmad, \_siesa-agents, .vscode, .github, .claude, .gemini, .resources, .mcp.json, \_bmad-output/design-artifacts - **Network endpoints:** https://platform-architecture-mcp-siesa-103767536676.us-east1.run.app/mcp, https://mcp.atlassian.com/v1/sse ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the installer., The installer copies package content into the consumer project., Its mappings overwrite broad AI-agent and editor control paths, including .claude, .gemini, .vscode, and .mcp.json., The installed MCP configuration adds remote servers and runs shadcn@latest through npx., The installed VS Code settings enable agent features and MCP discovery for other AI tools. - **Evidence against:** The Jira OAuth helper is separately user-invoked and uses Atlassian endpoints. ## Public findings ### 1.
