Cordon MCP

Cordon is a security gateway for MCP tool calls that provides sequence-aware policy enforcement, comprehensive audit logging, and human-in-the-loop approvals. It acts as a transparent proxy between LLM clients and MCP servers, blocking dangerous tool sequences like data exfiltration and requiring approval for sensitive operations via Slack or terminal.
