It also rewrites dependency files within its installation. - **Trigger:** npm install of basinfy in a likely project root - **Impact:** Installed IDE/agent clients can launch the package MCP server and follow injected configuration without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/cli/mcp-config.js, bin/basinfy-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T13:17:35.285Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall AI-agent configuration injection - **Attack narrative:** On installation, the package uses INIT\_CWD or cwd as the project root, resolves agent IDs, and silently invokes its MCP-config writer. The writer supports multiple unrelated AI-agent configuration and rule locations, causing installed agents to launch Basinfy's bundled MCP server. This occurs without an explicit setup command; the opt-out environment variable does not provide prior consent. - **Rationale:** Direct inspection confirms a postinstall hook that mutates foreign AI-agent control surfaces, matching the publish-block boundary. Obfuscation and unrelated dependency rewriting increase confidence; no network behavior is needed for this finding. - **Files touched:** scripts/postinstall.js, dist/cli/mcp-config.js, bin/basinfy-mcp.js, node\_modules/sharp/package.json, node\_modules/sharp/index.js, node\_modules/onnxruntime-web/package.json, node\_modules/onnxruntime-web/index.js, node\_modules/@xenova/transformers/src/utils/tensor.js, .mcp.json, .cline/mcp\_settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js on install., scripts/postinstall.js silently calls installMcpConfig for INIT\_CWD/project cwd., dist/cli/mcp-config.js defines multiple third-party agent MCP/rule targets and writes configs., Postinstall mutates bundled dependency paths for sharp, onnxruntime-web, and @xenova/transformers., Runtime artifacts, including dist/cli/mcp-config.js, are heavily obfuscated with anti-debugging code. - **Evidence against:** MCP setup is limited to a likely project root and offers BASINFY\_SKIP\_MCP=1., No concrete network endpoint or credential-exfiltration path was confirmed. ## Public findings ### 1.
