The affected client may launch a later package release as an MCP server. - **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:** 0.2.32 - **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. The npm postinstall hook automatically registers brokre as an MCP server in detected client configuration files. This changes global AI-client control configuration without a consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-07T23:04:11.389Z - **Finished:** 2026-10-07T23:04:37.691Z - **Download time:** 504 ms - **Static scan time:** 262 ms - **AI review time:** 25535 ms - **Total time:** 26302 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The npm postinstall hook automatically registers brokre as an MCP server in detected client configuration files. This changes global AI-client control configuration without a consent prompt. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** The affected client may launch a later package release as an MCP server. - **Evidence paths:** package.json, postinstall.js, setup-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T23:04:37.691Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs setup-mcp.js, which writes brokre entries to detected MCP configuration locations; the entry invokes brokre@latest through npx. - **Attack narrative:** During npm installation, postinstall.js invokes setup-mcp.js. That script detects MCP clients and writes a brokre server entry to their global configuration without asking first. The entry uses npx to run brokre@latest, so a later client launch can retrieve and run a changing release. - **Rationale:** The package performs unconsented install-time writes to global AI-client MCP configuration and registers a command that resolves brokre@latest. This is a concrete AI-agent control-surface hijack under the install-control policy. - **Files touched:** package.json, postinstall.js, setup-mcp.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook runs postinstall.js automatically., The hook invokes setup-mcp.js, which writes configuration for detected MCP clients., The setup adds brokre to global MCP configuration without a consent prompt., The registered command runs brokre@latest through npx, enabling later retrieval of a changing release., The setup detects Cursor and other client configuration locations. - **Evidence against:** The setup skips clients it does not detect and preserves existing entries unless forced., The package provides environment-variable opt-outs for its binary download and MCP setup. ## Affected versions and remediation This report applies to brokre@0.2.32. - Avoid installing brokre@0.2.32. 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.
