groundhog-mcp 0.9.0

Stealth-browser grounding tools for AI agents, over MCP

groundhog-mcp

Safe, self-hosted web grounding for AI agents and crawlers. An MCP server that fetches live web pages through a real, stealth-patched Chrome (over CDP) and returns clean Markdown with provenance — with a built-in SSRF guard and per-domain rate limiting.

Requires a running stealth browser (CDP endpoint). See the project README for setup: https://github.com/dmytrome/groundhog

Install

uvx groundhog-mcp

MCP client config (Claude Desktop / Cursor / Windsurf):

{
  "mcpServers": {
    "groundhog": {
      "command": "uvx",
      "args": ["groundhog-mcp"],
      "env": { "CDP_URL": "http://127.0.0.1:9222" }
    }
  }
}

Tools

• read_url(url, format="markdown", max_tokens=None) — fetch a page and return clean Markdown plus provenance (final_url, title, fetched_at, truncated).
• status() — check whether the stealth browser is reachable.
