# Guardrail MCP

Small, free, read-only Remote MCP for deterministic action preflight.

It exposes two tools:

- `get_guardrail_capabilities`
- `assess_action_risk`

The check detects a deliberately small set of high-risk patterns: credential exposure, fund movement, external writes, and instruction overrides. It does not execute an action, persist a request, authenticate a user, charge a payment, call AI, or fetch external URLs.

## Local use

```bash
npm run check
npm test
npm run dev
```

Endpoints: `GET /`, `GET /health`, and stateless Streamable HTTP `POST /mcp`.

## Boundary

This is an informational deterministic preflight, not a safety guarantee or legal, financial, or security advice. Deployment and any public endpoint require separate approval.
