⚙️ Usage

1. Run MCP Inspector

uv run fastmcp dev main.py

2. Install MCP Server in Claude Desktop

uv run fastmcp install claude-desktop main.py

After installation, update your claude_desktop_config.json:

"args": [
  "--directory",
  "D:\\Practice-Projects\\expense-tracker-mcp",
  "run",
  "fastmcp",
  "run",
  "main.py"
]

🧠 Notes

• Ensure your Supabase connection string is properly configured in .env.
• The server communicates through MCP Cloud and uses Claude Desktop as the client.
