Quick Start

Prerequisites

• Python 3.13 (required — Python 3.14+ is not supported due to SearXNG incompatibility)

Add to mcp.json

uvx (Recommended)

{
  "mcpServers": {
    "wet": {
      "command": "uvx",
      "args": ["--python", "3.13", "wet-mcp@latest"],
      "env": {
        "API_KEYS": "GOOGLE_API_KEY:AIza..."
      }
    }
  }
}

Warning: You must specify --python 3.13 when using uvx. Without it, uvx may pick Python 3.14+ which causes SearXNG search to fail silently (RuntimeError: can't register atexit after shutdown in DNS resolution).

That's it! On first run:

1. Automatically installs SearXNG from GitHub
2. Automatically installs Playwright chromium + system dependencies
3. Starts embedded SearXNG subprocess
4. Runs the MCP server

Docker

{
  "mcpServers": {
    "wet": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "API_KEYS", "n24q02m/wet-mcp:latest"],
      "env": {
        "API_KEYS": "GOOGLE_API_KEY:AIza..."
      }
    }
  }
}

Without uvx

pip install wet-mcp
wet-mcp
