# SINT Protocol

> Use this tool when you need to secure and control AI agent interactions with downstream MCP servers, enforcing capability-token policies to prevent unauthorized access. The SINT Protocol solves security and compliance problems by intercepting tool calls and allowing, denying, or escalating them to human approval. It provides inputs for policy configuration and outputs for approval workflows, audit trails, and token management, making it ideal for use cases requiring strict access control and auditing.

It also exposes built-in operator tools for approval workflows, audit trail queries, token management, voice/HUD output, and hierarchical
