The enforcement layer for AI agents. Intercept enforces hard, deterministic limits on what agents can do at the MCP transport layer — before execution.

Intercept is a deterministic enforcement proxy for the Model Context Protocol (MCP). It sits between an AI agent and an MCP server, evaluating every tools/call request against YAML-defined policies. Violating calls are blocked at the transport layer before reaching the upstream server.

Deterministic limits mean agents can't talk their way past safety policies.

Good for production deployments where probabilistic guardrails aren't acceptable.

Hard enforcement layer for AI agent behavior is something that's been missing.

Policy definition is clear, easy to audit what constraints are active.

Enforcement happens at the MCP layer, not in the agent prompt — the right architecture.
