AI Security Review
scanned 4mo ago · by lpm-firewall-aiSource 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.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
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
Mechanism
unconsented AI-agent hook and slash-command installation
Policy 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.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 94.0% confidence with low false-positive risk.
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
