Overview

Groundhog is a self-hosted web grounding server for AI agents and crawlers. It runs a stealth-configured Chrome browser and exposes it over the Model Context Protocol (MCP), allowing agents to fetch and interact with web pages while avoiding detection. Written in Python, it is designed for safe, controlled browsing.
