Cordon Overview

Cordon MCP server places a security gateway between an AI agent and connected MCP servers. It intercepts tool calls, applies server-level and tool-level policies, records structured audit events, and can pause selected operations for human approval. Use it when agents need controlled access to databases, filesystems, APIs, or other MCP-backed systems without changing those servers. Configuration is defined in a TypeScript file, and the CLI can import an existing Claude Desktop MCP configuration.

Primary Use Cases for Cordon:
  • Restrict database MCP servers to read-only access
  • Require approval before agents execute write operations
  • Audit every tool call for review or compliance
  • Hide sensitive tools from an MCP client
