A package install can add a Basinfy MCP command to foreign AI-agent control surfaces without an explicit user setup command. - **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:** 1.0.12 - **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 configures its MCP server for detected AI agents in the invoking project. It also mutates installed dependency contents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-21T03:02:54.547Z - **Finished:** 2026-08-21T03:03:48.616Z - **Download time:** 509 ms - **Static scan time:** 7993 ms - **AI review time:** 45565 ms - **Total time:** 54069 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically configures its MCP server for detected AI agents in the invoking project. It also mutates installed dependency contents. - **Trigger:** npm postinstall - **Impact:** A package install can add a Basinfy MCP command to foreign AI-agent control surfaces without an explicit user setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/cli/mcp-config.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T03:03:48.616Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic agent-config injection and dependency rewriting - **Attack narrative:** On installation, the postinstall script selects the invoking project, detects installed AI agents, and invokes an obfuscated MCP-config writer. This creates a package-controlled MCP entry in external agent configuration rather than requiring an explicit user command. The same hook deletes/replaces dependency directories and patches a dependency source file. - **Rationale:** This is unconsented postinstall mutation of foreign AI-agent control surfaces, meeting the block policy. Obfuscation and additional dependency rewriting raise confidence; no exfiltration endpoint was needed for this verdict. - **Files touched:** scripts/postinstall.js, dist/cli/mcp-config.js, node\_modules/sharp/, node\_modules/onnxruntime-web/, node\_modules/@xenova/transformers/src/utils/tensor.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes automatically on npm install., It auto-detects agents and installs MCP configuration in the invoking project., The lifecycle script also deletes/replaces dependency directories and patches a dependency file., Distributed MCP configuration code is deliberately obfuscated. - **Evidence against:** MCP setup can be disabled with BASINFY\_SKIP\_MCP=1., The postinstall checks for a likely project root., No concrete network endpoint or credential exfiltration was confirmed. ## Public findings ### 1.
