Finance Intelligence MCP is a production-ready **Model Context Protocol (MCP)** server that enables AI assistants (like Claude, Cursor, and others) to securely manage and analyze personal finances through natural language. 

Released under the MIT License and designed to be extended with additional finance tools.

## 💾 Installation & Setup

### 1. Quick Setup (Shortcut)
If you have `uv` installed, get started in 2 lines:
```bash
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](https://supabase.com/) 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:
```bash
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:
```bash
pip install -e .
```

### 3. Client Integration

#### Claude Desktop Setup
1. Open your Claude configuration file (`claude_desktop_config.json`):
   * **Windows**: Press `Win + R`, paste `%APPDATA%\Claude\claude_desktop_config.json` and press Enter.
   * **macOS**: Paste `~/Library/Application Support/Claude/claude_desktop_config.json` in Finder's Go to Folder.
2. Add this entry to `mcpServers`:

```json
{
  "mcpServers": {
    "finance-intelligence": {
      "command": "uv",
      "args": [
        "--directory",
        "REPLACE_WITH_ABSOLUTE_PATH_TO_CLONED_DIRECTORY",
        "run",
        "python",
        "main.py"
      ],
      "env": {
        "DATABASE_URL": "REPLACE_WITH_YOUR_SUPABASE_CONNECTION_STRING"
      }
    }
  }
}
```
3. Save and completely **restart Claude Desktop**.

#### Cursor IDE Setup
1. Go to **Settings** > **Features** > **MCP**.
2. Click **+ Add New MCP Server**:
   * **Name**: `Finance Intelligence`
   * **Type**: `command`
   * **Command**: 
     ```bash
     uv --directory "REPLACE_WITH_ABSOLUTE_PATH_TO_CLONED_DIRECTORY" run python main.py
     ```
3. Click **+ Add Env Var**:
   * **Key**: `DATABASE_URL`
   * **Value**: `REPLACE_WITH_YOUR_SUPABASE_CONNECTION_STRING`
4. Click **Save** and refresh.

## 💡 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:
```json
"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.
