The Alpaca MCP Server enables LLMs like Claude to interact with the Alpaca trading API through natural language. This integration allows you to trade stocks, check positions, fetch market data, and manage your account simply by having a conversation with your AI assistant.
Clone the repository:
git clone https://github.com/YOUR_USERNAME/alpaca-mcp.git
cd alpaca-mcp
Install the required packages:
pip install mcp alpaca-py python-dotenv
Create a .env
file with your Alpaca API credentials:
API_KEY_ID=your_alpaca_api_key
API_SECRET_KEY=your_alpaca_secret_key
Start the server by running:
python alpaca_mcp_server.py
claude_desktop_config.json
:{
"mcpServers": {
"alpaca": {
"command": "python",
"args": [
"/path/to/alpaca_mcp_server.py"
],
"env": {
"API_KEY_ID": "your_alpaca_api_key",
"API_SECRET_KEY": "your_alpaca_secret_key"
}
}
}
}
The server provides access to these trading functions:
Once connected to Claude, you can ask questions like:
By default, the server uses Alpaca's paper trading. To use real money trading, change paper=True
to paper=False
in the TradingClient
initialization.
This MCP server has access to your Alpaca account and can execute real trades. Always carefully review Claude's suggestions before approving any trading actions.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"cursor-rules-mcp": {
"command": "npx",
"args": [
"-y",
"cursor-rules-mcp"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
