**Put auth, rate limits, spend caps, and audit logs in front of any MCP server — without changing the server.**

```bash
pip install "bonanza-mcp-guard[yaml]"
mcp-guard scan
mcp-guard serve --config mcp-guard.yaml
```

> **PyPI:** package [`bonanza-mcp-guard`](https://pypi.org/project/bonanza-mcp-guard/) (name `mcp-guard` was taken). CLI is still `mcp-guard`.

![Demo](docs/demo.gif)

Sits in front of any MCP server over stdio. Zero required dependencies.

Complements static scanners like [mcp-scan](https://github.com/invariantlabs-ai/mcp-scan) with a **runtime stdio gateway** (auth, limits, audit).

## Why mcp-guard?

| Without mcp-guard | With mcp-guard |
|---|---|
| Any agent calls any tool | Agent must authenticate (API key / JWT) |
| No spend ceiling | Per-session spend caps, per-hour rate limits |
| No audit trail | Every request logged to JSONL |
| Server exposed directly | Gateway wraps server — zero code changes |

## The problem

Security research in 2026 reported **1,800+ internet-exposed MCP endpoints** with **no authentication**. Any MCP client can invoke tools with no identity, no spend ceiling, and no audit trail.

`mcp-guard` adds a gateway layer — Claude Desktop, Cursor, Windsurf, or custom agents talk to `mcp-guard`; it talks to your real MCP server.
