Installed AI clients can automatically run a remotely updated brokre package, without an explicit setup command from the user. - **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:** 0.2.25 - **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 modifies global MCP settings for detected AI clients. Those settings launch brokre through npx and select the latest registry release at future client startup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-05T06:42:18.407Z - **Finished:** 2026-09-05T06:42:58.043Z - **Download time:** 508 ms - **Static scan time:** 239 ms - **AI review time:** 38887 ms - **Total time:** 39636 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies global MCP settings for detected AI clients. Those settings launch brokre through npx and select the latest registry release at future client startup. - **Trigger:** npm installation invokes the postinstall lifecycle hook. - **Impact:** Installed AI clients can automatically run a remotely updated brokre package, without an explicit setup command from the user. - **Evidence paths:** package.json, setup-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T06:42:58.043Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall MCP configuration injection across multiple AI-client profiles. - **Attack narrative:** The npm postinstall hook runs setup-mcp.js. It detects several installed AI clients and writes global MCP configuration entries that execute npx -y brokre@latest. This mutates a broad foreign AI-agent control surface during installation and causes future client starts to resolve and execute a registry-selected release. - **Rationale:** This is an unconsented postinstall mutation of multiple foreign AI-agent configuration surfaces. The injected latest-version npx command adds a continuing remote execution path. - **Files touched:** ~/.cursor/mcp.json, ~/Library/Application Support/Code/User/mcp.json, ~/.claude.json, ~/.kimi-code/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.openclaw/openclaw.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs setup-mcp.js automatically during npm postinstall., The postinstall script registers an MCP server in global configurations for detected Cursor, VS Code, Claude, Trae, Kimi, Windsurf, and OpenClaw installations., The injected server command uses npx with brokre@latest, allowing later execution of a registry-selected package release., Configuration writes create parent directories, back up existing files, and overwrite the JSON configuration. - **Evidence against:** Automatic setup can be disabled with an environment variable and is skipped in CI., The setup checks for installed applications and preserves unrelated MCP entries. ## Public findings ### 1.
