A package installation can cause IDE/agent clients to launch the package's MCP server and grant it project-context access. - **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:** 1.0.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically registers Basinfy's MCP server with detected or default third-party AI coding agents in the consuming project. This changes agent control configuration without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-30T13:44:19.487Z - **Finished:** 2026-07-30T13:45:04.681Z - **Download time:** 503 ms - **Static scan time:** 3199 ms - **AI review time:** 41489 ms - **Total time:** 45194 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically registers Basinfy's MCP server with detected or default third-party AI coding agents in the consuming project. This changes agent control configuration without an explicit user command. - **Trigger:** npm installation in a directory recognized as a project root, unless BASINFY\_SKIP\_MCP=1 is pre-set. - **Impact:** A package installation can cause IDE/agent clients to launch the package's MCP server and grant it project-context access. - **Evidence paths:** package.json, scripts/postinstall.js, dist/cli/mcp-config.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-30T13:45:04.681Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven detection and rewriting of AI-agent MCP configuration - **Attack narrative:** Installing the package invokes scripts/postinstall.js. For a recognized project it loads the obfuscated MCP configuration module, detects installed AI agents or selects defaults, then writes a basinfy MCP server entry into their project configuration. The registration makes third-party agent clients launch package-provided code without the user having run the documented setup command. - **Rationale:** This is concrete unconsented postinstall mutation of a broad foreign AI-agent control surface, meeting the blocking policy. The documented manual workflow and opt-out do not make the default lifecycle mutation consented. - **Files touched:** package.json, scripts/postinstall.js, dist/cli/mcp-config.js, .mcp.json, .vscode/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js automatically., scripts/postinstall.js calls installMcpConfig for the install project without a user command., dist/cli/mcp-config.js detects agents, falls back to default agents, and writes a basinfy MCP entry., The config writer targets foreign AI-agent MCP configuration such as .mcp.json and .vscode/mcp.json., Obfuscated dist/cli/mcp-config.js obscures this install-time control-surface mutation. - **Evidence against:** README.md documents an explicit basinfy install wizard and manual MCP configuration., The lifecycle hook offers BASINFY\_SKIP\_MCP=1, but it is opt-out after automatic installation behavior. ## Public findings ### 1.
