Adds a package-controlled MCP entry to detected AI-agent configuration without an explicit setup command; opaque configuration code prevents reliable audit of its exact writes. - **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:** 1.1.1 - **Selected version is latest:** No - **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 runs code that detects the consumer project and silently registers MCP configuration for one or more agents. The same hook also mutates installed dependencies and can run a dependency installer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-12T13:53:14.216Z - **Finished:** 2026-09-12T13:54:40.427Z - **Download time:** 762 ms - **Static scan time:** 8383 ms - **AI review time:** 77066 ms - **Total time:** 86211 ms The recorded confidence comes from the underlying analysis.

The same hook also mutates installed dependencies and can run a dependency installer. - **Trigger:** npm installation of the package as a project dependency. - **Impact:** Adds a package-controlled MCP entry to detected AI-agent configuration without an explicit setup command; opaque configuration code prevents reliable audit of its exact writes. - **Evidence paths:** package.json, scripts/postinstall.js, bin/native-resolve.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T13:54:40.427Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic MCP configuration and dependency mutation from postinstall. - **Attack narrative:** On installation, the manifest runs scripts/postinstall.js. For a detected consumer project, it loads an obfuscated MCP configuration module, finds agent identifiers, and calls installMcpConfig silently. This changes an AI-agent control surface without requiring the user to run a setup command. The hook also deletes and recreates installed dependency directories, patches a dependency source file, and may execute onnxruntime-node's installer with inherited environment variables. - **Rationale:** This is an unconsented postinstall mutation of a consumer AI-agent control surface, compounded by opaque configuration code and unrelated dependency rewrites. Opt-out variables and the global-install guard do not make the automatic project-install behavior consented. - **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, node\_modules/onnxruntime-node/script/install.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall script automatically., Postinstall silently configures MCP for detected agents in the consumer project., Postinstall replaces installed packages and patches a transformer dependency., Postinstall can execute a nested onnxruntime installer., The MCP configuration implementation is deliberately obfuscated. - **Evidence against:** Global installs avoid the home Cursor configuration., Environment variables can disable the postinstall or MCP writes. ## Affected versions and remediation This report applies to basinfy@1.1.1. - Avoid installing basinfy@1.1.1. 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.
