💾 Installation & Setup

1. Quick Setup (Shortcut)

If you have uv installed, get started in 2 lines:

git clone https://github.com/Ronit-019/Finance-Intelligence-MCP.git
cd Finance-Intelligence-MCP
uv sync

2. Detailed Installation

Step A: Get a PostgreSQL Connection URL

The easiest, free option is Supabase:

1. Go to Supabase and create a free project.
2. Go to Project Settings (gear icon) > Database.
3. Under Connection string, select URI and copy the string.
   • Example: postgresql://postgres.[your-project-ref]:[your-password]@aws-0-us-east-1.pooler.supabase.com:5432/postgres
   • (Replace [your-password] with your database password).

Step B: Clone the Repository

Clone the codebase to a directory on your machine:

git clone https://github.com/Ronit-019/Finance-Intelligence-MCP.git
cd Finance-Intelligence-MCP

Copy the absolute path of this directory (e.g. C:/Users/Admin/Desktop/Finance-Intelligence-MCP). Note: Always use forward slashes (/) for paths in JSON configs.

Step C: Install Dependencies

If you do not have uv installed, install from the project metadata:

pip install -e .

        "--directory",
        "REPLACE_WITH_ABSOLUTE_PATH_TO_CLONED_DIRECTORY",
        "run",
        "python",
        "main.py"
      ],
      "env": {
        "DATABASE_URL": "REPLACE_WITH_YOUR_SUPABASE_CONNECTION_STRING"
      }
    }

💡 Troubleshooting

1. uv: command not found

If the client cannot locate uv, update your config file to run standard Python:

• Ensure you ran pip install -e . inside the repository.
• Update config:

"finance-intelligence": {
  "command": "python",
  "args": [
    "REPLACE_WITH_ABSOLUTE_PATH_TO_CLONED_DIRECTORY/main.py"
  ],
  "env": {
    "DATABASE_URL": "REPLACE_WITH_YOUR_SUPABASE_CONNECTION_STRING"
  }
}

2. Invalid DATABASE_URL / PostgreSQL Connection Errors

• Make sure you replaced [your-password] with your actual database password in the Supabase URI string.
• Ensure there are no surrounding spaces or special characters in the URL string.
• Verify your Supabase instance is active and not paused.

3. Claude Not Detecting the Server

• Double check that the folder paths in claude_desktop_config.json use forward slashes (/), even on Windows.
• Check the logs at %APPDATA%\Claude\logs\mcp*.log (Windows) or ~/Library/Logs/Claude/mcp*.log (macOS) to see the exact startup error.
