### Description (declared)

# mcp-gateway

[![PyPI](https://img.shields.io/pypi/v/mcp-gateway)](https://pypi.org/project/mcp-gateway/)
[![License](https://img.shields.io/github/license/MagnusCole/mcp-gateway)](LICENSE)

Unify multiple MCP servers behind a single endpoint. Lazy loading, auto-cleanup, Python plugins, role-based filtering.

## The Problem

If you use Claude Code or any MCP client with 3+ servers, you get:
- Multiple subprocesses (~50MB each)
- Duplicated config
- No centralized control
- No way to add custom Python tools without a full MCP server

## The Solution

`mcp-gateway` runs **one process** that proxies N MCP servers on-demand:

```
Claude Code / MCP Client
  │
  ▼
mcp-gateway (1 process)
  ├─ [plugin] Python @tool functions     ← in-process, 0 overhead
  ├─ [lazy]   filesystem-server          ← subprocess spawned on first call
  ├─ [lazy]   github-server              ← subprocess spawned on first call
  └─ [lazy]   playwright                 ← subprocess spawned on first call
      ↑
      5 min idle → auto-kill
```

## Install

```bash
pip install mcp-gateway
```

## Quick Start

### 1. Create `gateway.yaml`

```yaml
servers:
  filesystem:
    command: npx
    args: ["-y", "@modelcontextprotocol/server-filesystem", "/tmp"]

  github:
    command: npx
    args: ["-y", "@modelcontextprotocol/server-github"]
    env:
      GITHUB_TOKEN: "${GITHUB_TOKEN}"
    enabled: false

idle_timeout: 300
```

### 2. Run

**stdio** (for Claude Code):
```bash
mcp-gateway stdio --config gateway.yaml
```

**SSE** (for remote clients):
```bash
mcp-gateway serve --config gateway.yaml --port 8765
```

### 3. Add to Claude Code

```json
{
  "mcpServers": {
    "gateway": {
      "command": "mcp-gateway",
      "args": ["stdio", "--config", "/path/to/gateway.yaml"]
    }
  }
}
```

## Python Plugins

Add custom tools with zero boilerplate:

```python
from mcp_gateway import tool

@tool(descri…
