Quickstart Guide

Learn how to route your autonomous agent's LLM tool calls through the Out-of-Process MCP Gateway for strict Human-In-The-Loop approval.

1. The Problem

Giving an LLM direct access to a mutable API (like Stripe or AWS) is dangerous. If the agent hallucinates, it executes irreversible actions. The Guardrail API intercepts the JSON-RPC call before execution.

2. Wrapping your Agent

Simply point your agent's MCP base URL to the Gateway. No SDK rewrite required.

agent.ts

const client = new MCPClient({
  baseUrl: "https://api.guardrail.dev/v1/mcp",  headers: {
    "Authorization": "Bearer sk_live_12345"  }
});

3. The Diff Engine

When the Gateway intercepts the call, it generates a deterministic "dry-run" diff using our Reversal Matrix. The agent receives a PENDING_APPROVAL status, and the operation halts until a human reviews it in the Dashboard.
