Future agent sessions can load package-controlled prompts and start the package MCP server with the user's permissions. - **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:** 0.2.4 - **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 runs a postinstall installer that modifies detected AI-agent installations. It adds package-provided skills, commands, and an MCP server to user-level agent control surfaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-29T21:40:33.607Z - **Finished:** 2026-08-29T21:41:46.921Z - **Download time:** 503 ms - **Static scan time:** 1255 ms - **AI review time:** 71554 ms - **Total time:** 73314 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package runs a postinstall installer that modifies detected AI-agent installations. It adds package-provided skills, commands, and an MCP server to user-level agent control surfaces. - **Trigger:** npm installation when a supported agent CLI is present - **Impact:** Future agent sessions can load package-controlled prompts and start the package MCP server with the user's permissions. - **Evidence paths:** package.json, bin/astra.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T21:41:46.921Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic user-level AI-agent extension and MCP registration - **Attack narrative:** A normal npm install invokes the postinstall hook. The hook detects installed Claude, Codex, or Factory tooling, copies package-controlled skills and commands into their user-level directories, and registers an Astra MCP server. This changes separate AI-agent control surfaces without an explicit setup command or interactive consent, so subsequent agent sessions may execute package-controlled functionality under the user's permissions. - **Rationale:** The package performs unconsented postinstall mutation of foreign, user-level AI-agent control surfaces. This is concrete install-hook abuse even though no external exfiltration endpoint was confirmed. - **Files touched:** package.json, bin/astra.mjs, ~/.claude/skills, ~/.claude/commands, ~/.claude.json, ~/.codex/skills, ~/.codex/prompts, ~/.codex/config.toml, ~/.factory/skills, ~/.factory/commands, ~/.factory/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the installer during npm installation., The installer targets Claude, Codex, and Factory agent configuration locations in the user home directory., It copies packaged skills and commands into detected agent hosts without an explicit user command., It registers an MCP server through host CLIs and writes Factory MCP configuration. - **Evidence against:** No external network endpoint or credential-exfiltration path was confirmed., The visualizer binds to localhost by default and its HTTP requests are local routes. ## Public findings ### 1.
