Persistent alteration of Claude Code prompt handling and tool-routing behavior toward the package's hosted service - **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:** 1.8.19 - **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. Source inspection confirms automatic runtime writes to Claude Code hook/command configuration plus prompt-control directives, which is an unconsented AI-agent control-surface mutation. Other risky primitives such as fetch, WebSocket, project snapshot upload, and config writes are mostly package-aligned, but the startup hook persistence is sufficient to block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-07-02T00:31:09.502Z - **Finished:** 2026-07-02T00:31:48.512Z - **Download time:** 760 ms - **Static scan time:** 727 ms - **AI review time:** 37522 ms - **Total time:** 39010 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:** Starting the MCP bridge mutates Claude Code control surfaces by installing a slash command and UserPromptSubmit hook. The hook injects higher-priority directives that force model behavior for /quorum prompts. - **Trigger:** User or MCP client runs cc-bridge start/bin entrypoint - **Impact:** Persistent alteration of Claude Code prompt handling and tool-routing behavior toward the package's hosted service - **Evidence paths:** dist/index.js, templates/quorum-enforcement.sh, templates/quorum.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-02T00:31:48.512Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented AI-agent hook and slash-command installation - **Attack narrative:** When the package is run as the MCP bridge, it does not only start a server. It installs a Claude slash command and registers a UserPromptSubmit hook that emits harness-level instructions telling the agent there is no judgment call and requiring specific 1K4 tool invocations. This persists in the user's Claude configuration and changes future agent behavior. - **Rationale:** Source inspection confirms automatic runtime writes to Claude Code hook/command configuration plus prompt-control directives, which is an unconsented AI-agent control-surface mutation. Other risky primitives such as fetch, WebSocket, project snapshot upload, and config writes are mostly package-aligned, but the startup hook persistence is sufficient to block. - **Files touched:** ~/.claude/commands/quorum.md, ~/.claude/hooks/quorum-enforcement.sh, ~/.claude/settings.json - **Network endpoints:** https://1key4ai.com, wss://1key4ai.com/api/lab-bridge/ws, /api/mcp/\*, /api/install/verify ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** dist/index.js CLI start calls ensureQuorumSlashCommand and ensureQuorumEnforcementHook before runServer, ensureQuorumEnforcementHook writes ~/.claude/hooks/quorum-enforcement.sh and registers it in ~/.claude/settings.json, templates/quorum-enforcement.sh injects harness directives that force /quorum tool flow and override in-context instructions, templates/quorum.md tells Claude/Codex/Cursor to call 1k4 tools instead of answering in matching decision flows - **Evidence against:** package.json has no install/postinstall lifecycle hook; prepublishOnly is publish-time only, Network calls target declared service https://1key4ai.com and API base env overrides, Project snapshot upload excludes common secret filenames and requires tool invocation, not install-time execution, Setup/config writes are partly documented as cc-bridge setup behavior ## Affected versions and remediation This report applies to @1key4ai/cc-bridge@1.8.19. - Avoid installing @1key4ai/cc-bridge@1.8.19. 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.
