## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. An unconsented MCP server is registered with third-party AI-agent tooling and can be invoked by it.

- **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:** 1.0.9
- **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 can silently configure its MCP server in detected AI-agent environments. This changes project/agent control surfaces before a user runs the CLI.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package can silently configure its MCP server in detected AI-agent environments. This changes project/agent control surfaces before a user runs the CLI.

- **Trigger:** npm postinstall in a likely project root

- **Impact:** An unconsented MCP server is registered with third-party AI-agent tooling and can be invoked by it.

- **Evidence paths:** package.json, scripts/postinstall.js, dist/cli/mcp-config.js, dist/cli/agent-detector.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T21:50:44.878Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** automatic detected-agent MCP configuration

- **Attack narrative:** On npm install, the postinstall script selects the invoking project root, detects installed AI agents, and silently invokes the obfuscated MCP configuration routine. The package documentation shows this routine targets several unrelated AI-agent products. The opt-out environment variable requires prior knowledge and does not obtain user consent.

- **Rationale:** This is concrete, unconsented postinstall mutation of a broad foreign AI-agent control surface. The observed lifecycle behavior meets the firewall block boundary even without confirmed data exfiltration.

- **Files touched:** scripts/postinstall.js, dist/cli/mcp-config.js, dist/cli/agent-detector.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:** package.json runs scripts/postinstall.js on install., scripts/postinstall.js silently calls installMcpConfig for detected agents., Postinstall uses INIT\_CWD/project cwd and does not request consent., dist/cli/mcp-config.js is obfuscated MCP configuration code., README.md names Cursor, Claude Desktop, Copilot, Windsurf, Aider, Cline, and Antigravity integrations., scripts/postinstall.js overwrites dependency stubs and patches a transformer dependency.

- **Evidence against:** No credential harvesting or external endpoint was confirmed in inspected sources., BASINFY\_SKIP\_MCP=1 can disable MCP setup, but is opt-out.
