It's a single dependency-free Python file that reads the live JSON from this site. It works with Claude Desktop, Cursor and any MCP client.

1 · Download and run

curl -O https://adstackwatch.com/mcp/server.py
python3 server.py   # stdio, Python 3.9+

Or serve it over HTTP

python3 server.py --http --port 8765
# POST JSON-RPC to http://127.0.0.1:8765/mcp

2 · Add it to your client (claude_desktop_config.json or .cursor/mcp.json)
