After installing as a UV tool, edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "altic-mcp": {
      "command": "altic-mcp-server"
    }
  }
}

1. Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "altic-mcp": {
      "command": "uv",
      "args": ["run", "/FULL/PATH/TO/altic-mcp/server.py"]
    }
  }
}

Replace /FULL/PATH/TO/altic-mcp with your actual path (e.g., /Users/johndoe/Documents/altic-mcp).

2. Restart Claude Desktop (Command + Q, then reopen)

3. Look for the 🔨 hammer icon in the chat interface to see available tools
