Why it matters
Warden targets the MCP tool-calling layer where agentic AI systems are exposed to prompt injection and secret exfiltration, giving defenders a proxy-level control point to enforce policy and audit agent actions.
Warden is an open-source drop-in security proxy for the Model Context Protocol (MCP) that adds policy enforcement, tamper-evident audit logging, human approval gates, and defenses against prompt injection and secret exfiltration. The GitHub repository includes policies, examples, a SECURITY.md threat model, and a CI test matrix, and is configured via one line of config with no code changes.
