HaltState MCP

HaltState MCP is an AI policy enforcement platform that connects agents to automated governance and compliance.

HaltState provides SDKs for Python, TypeScript, Go, Java, and Rust to connect AI agents and backend tools to automated policy enforcement. Developers integrate the SDK into a backend service or worker immediately before high-risk actions like refunds, payments, or PII exports. The platform evaluates actions to return allow, approval required, or deny decisions before business systems execute them. Users can draft policies with an AI Policy Assistant and connect an MCP client to search activity and verify evidence. It is built for engineering and security teams seeking automated agent governance.
