Installation Methods

1. Choose Your Installation Method

This section shows manual installation of Alpaca MCP Server.

Method 1: uvx

Method 2: Install.py

Clone the repository and navigate to the directory:

Execute the following commands in your terminal:

Method 3: Docker

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

Project Structure

After installing/cloning and activating the virtual environment, your directory structure should look like this:

2. Create and edit a .env file for your credentials in the project directory

1. Copy the example environment file in the project root by running this command:

   cp .env.example .env

2. Replace the credentials (e.g. API keys) in the .env file:

   ALPACA_API_KEY = "your_alpaca_api_key_for_paper_account" ALPACA_SECRET_KEY = "your_alpaca_secret_key_for_paper_account" ALPACA_PAPER_TRADE = True TRADE_API_URL = None TRADE_API_WSS = None DATA_API_URL = None STREAM_DATA_WSS = None DEBUG = False

3. Start the MCP Server (Remote Setup Only)

Note: You typically don't need to manually start the server for local usage. MCP clients like Claude Desktop and Cursor will automatically start the server when configured.

You only need to manually start the server if you're setting it up for remote access (e.g., running the server on a remote machine and connecting from a different computer).

For remote usage (HTTP transport):

Available transport options:

• --transport stdio (default): Standard input/output for local client connections (automatically used by MCP clients)

• --transport http: HTTP transport for remote client connections (default: 127.0.0.1:8000)

• --transport sse: Server-Sent Events transport for remote connections (deprecated)

• --host HOST: Host to bind the server to for HTTP/SSE transport (default: 127.0.0.1)

• --port PORT: Port to bind the server to for HTTP/SSE transport (default: 8000)

Note: For more information about MCP transport methods, see the official MCP transport documentation.

4. Switching API Keys for Live Trading

This MCP server connects to Alpaca's paper Trading API by default for safe testing. To enable live trading with real funds or switch between different accounts, you need to update API credentials in two places:

1. .env (used by MCP server)

2. MCP client config JSON (used by MCP client like Claude Desktop, Cursor, etc.)

Important: The MCP client configuration overrides the .env file. When using an MCP client, the credentials in the client's JSON config take precedence.

Place 1: Update .env File (Used by MCP Server)

For direct CLI usage or when running the server directly:

Option 1: Run the init command again to update your .env file:

Option 2: Manually edit the .env file in your current directory:

Place 2: Update MCP Client Config (Used by MCP Client)

For MCP client users (Claude Desktop, Cursor, VS Code, etc.):

Step 1: Edit your MCP client configuration file:

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

• Cursor: ~/.cursor/mcp.json

• VS Code: .vscode/mcp.json (workspace) or user settings.json

Step 2: Update the API keys in the env section:

For uvx installations:

Step 3: Restart your MCP client (Claude Desktop, Cursor, etc.)

MCP Client Configuration

Below you'll find step-by-step guides for connecting the Alpaca MCP server to various MCP clients. Choose the section that matches your preferred development environment or AI assistant.

Claude Desktop Configuration

Method 1: uvx (Recommended)

Simple and modern approach:

1. Install and configure the server:

   uvx alpaca-mcp-server init

2. Open Claude Desktop → Settings → Developer → Edit Config

3. Add this configuration:

   { "mcpServers": { "alpaca": { "type": "stdio", "command": "uvx", "args": ["alpaca-mcp-server", "serve"], "env": { "ALPACA_API_KEY": "your_alpaca_api_key", "ALPACA_SECRET_KEY": "your_alpaca_secret_key" } } } }

4. Restart Claude Desktop and start trading!

Method 2: install.py (Alternative local setup)

Choose claude when prompted. The installer sets up .venv, writes .env, and updates claude_desktop_config.json. Restart Claude Desktop.

Claude Code Configuration

Use this local setup to register the server with Claude Code.

Prerequisites:

• Claude Code CLI installed and authenticated (see Anthropic docs below)

• Alpaca API keys (paper or live)

Option 1: Using uvx (Recommended)

Requires uv installed: https://docs.astral.sh/uv/getting-started/installation/

1. Initialize the server (creates a local .env):

2. Register the MCP server via Claude Code:

• --scope user adds the server globally (available in all projects)

• Omit --scope user to add it only to the current project

Option 2: Using Docker

Requires Docker installed and the image built locally (see Docker Configuration).

• --scope user adds the server globally (available in all projects)

• Omit --scope user to add it only to the current project

Verify

• Launch the Claude Code CLI: claude

• Run /mcp and confirm the alpaca server and tools are listed

• If the server doesn't appear, try claude mcp list to review registered servers

Cursor Configuration

To use Alpaca MCP Server with Cursor, please follow the steps below. The official Cursor MCP setup document is available here: https://docs.cursor.com/context/mcp

Prerequisites

• Cursor IDE installed with Claude AI enabled

• Python and virtual environment set up (follow Installation steps above)

Local setup via install.py (recommended for local)

During the prompts, choose cursor and enter your API keys. The installer creates a .venv, writes a .env, and auto-updates ~/.cursor/mcp.json. Restart Cursor to load the config.

Note: If uv is not installed, the installer can help you install it. You may need to restart your terminal after installing uv so uv/uvx are recognized. Reference: https://docs.astral.sh/uv/getting-started/installation/

Configure the MCP Server

Method 1: Using Cursor Directory UI For Cursor users, you can quickly install Alpaca from the Cursor Directory in just a few clicks.

1. Find Alpaca in the
2. Click "Add to Cursor" to launch Cursor on your computer
3. Enter your API Key and Secret Key
4. You’re all set to start using it

Method 2: Using JSON Configuration

Create or edit ~/.cursor/mcp.json (macOS/Linux) or %USERPROFILE%\.cursor\mcp.json (Windows):

VS Code Configuration

To use Alpaca MCP Server with VS Code, please follow the steps below.

VS Code supports MCP servers through GitHub Copilot's agent mode. The official VS Code setup document is available here: https://code.visualstudio.com/docs/copilot/chat/mcp-servers

Prerequisites

• VS Code with GitHub Copilot extension installed and active subscription

• Python and virtual environment set up (follow Installation steps above)

• MCP support enabled in VS Code (see below)

1. Enable MCP Support in VS Code

1. Open VS Code Settings (Ctrl/Cmd + ,)

2. Search for "chat.mcp.enabled" to check the box to enable MCP support

3. Search for "github.copilot.chat.experimental.mcp" to check the box to use instruction files

2. Configure the MCP Server (uvx recommended)

Recommendation: Use workspace-specific configuration (.vscode/mcp.json) instead of user-wide configuration. This allows different projects to use different API keys (multiple paper accounts or live trading) and keeps trading tools isolated from other development work.

For workspace-specific settings:

1. Create .vscode/mcp.json in your project root.

2. Add the Alpaca MCP server configuration manually to the mcp.json file:

   { "mcp": { "servers": { "alpaca": { "type": "stdio", "command": "uvx", "args": ["alpaca-mcp-server", "serve"], "env": { "ALPACA_API_KEY": "your_alpaca_api_key", "ALPACA_SECRET_KEY": "your_alpaca_secret_key" } } } } }

   Note: Replace ${workspaceFolder} with your actual project path. For example:

   • Linux/macOS: /Users/username/Documents/alpaca-mcp-server

   • Windows: C:\\Users\\username\\Documents\\alpaca-mcp-server

For user-wide settings:

To configure an MCP server for all your workspaces, you can add the server configuration to your user settings.json file. This allows you to reuse the same server configuration across multiple projects. Specify the server in the mcp VS Code user settings (settings.json) to enable the MCP server across all workspaces.

PyCharm Configuration

To use the Alpaca MCP Server with PyCharm, please follow the steps below. The official setup guide for configuring the MCP Server in PyCharm is available here: https://www.jetbrains.com/help/ai-assistant/configure-an-mcp-server.html

PyCharm supports MCP servers through its integrated MCP client functionality. This configuration ensures proper logging behavior and prevents common startup issues.

1. Open PyCharm Settings

   • Go to File → Settings

   • Navigate to Tools → Model Context Protocol (MCP) (or similar location depending on PyCharm version)

2. Add New MCP Server

   • Click Add or + to create a new server configuration. You can also import the settings from Claude by clicking the corresponding button.

   • Name: Enter any name you prefer for this server configuration (e.g., Alpaca MCP).

   • type: "stdio",

   • Command: "uvx",

   • Arguments: ["alpaca-mcp-server", "serve"]

3. Set Environment Variables Add the following environment variables in the Environment Variables parameter:

   ALPACA_API_KEY="your_alpaca_api_key" ALPACA_SECRET_KEY="your_alpaca_secret_key" MCP_CLIENT=pycharm

Docker Configuration (locally)

Build the image:

Add to Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

Replace your_alpaca_api_key and your_alpaca_secret_key with your actual Alpaca credentials, then restart Claude Desktop.

HTTP Transport for Remote Usage

For users who need to run the MCP server on a remote machine (e.g., Ubuntu server) and connect from a different machine (e.g., Windows Claude Desktop), use HTTP transport:

Server Setup (Remote Machine)

Remote Access Options:

1. Direct binding: Use --host 0.0.0.0 to bind to all interfaces for direct remote access

2. SSH tunneling: ssh -L 8000:localhost:8000 user@your-server for secure access (recommended for localhost binding)

3. Reverse proxy: Use nginx/Apache to expose the service securely with authentication

Client Setup

Update your Claude Desktop configuration to use HTTP:

Troubleshooting HTTP Transport Issues

• Port not listening: Ensure the server started successfully and check firewall settings

• Connection refused: Verify the server is running on the expected host:port

• ENOENT errors: Make sure you're using the updated server command with --transport http

• Remote access: Use --host 0.0.0.0 for direct access, or SSH tunneling for localhost binding

• Port conflicts: Use --port <PORT> to specify a different port if default is busy
