Alphavantage MCP server

The Alpha Vantage MCP Server provides a bridge between the Alpha Vantage stock market data API and applications using the Model Context Protocol (MCP). This server allows you to integrate real-time and historical stock market data into your MCP-compatible applications like Claude Desktop.

Configuration

Getting an API Key

1. Sign up for a Free Alphavantage API key
2. Add the API key to your environment variables as ALPHAVANTAGE_API_KEY

Installation

Clone the repository to your local machine:

git clone https://github.com/calvernaz/alphavantage.git

Server Modes

The AlphaVantage server can run in two different modes:

Stdio Server (Default)

This is the standard MCP server mode used for tools like Claude Desktop.

alphavantage
# or explicitly:
alphavantage --server stdio

Streamable HTTP Server

This mode provides real-time updates via HTTP streaming.

alphavantage --server http --port 8080

Server Options

• --server: Choose between stdio (default) or http server mode
• --port: Specify the port for the Streamable HTTP server (default: 8080)

Integration with Claude Desktop

To use with Claude Desktop, add this configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "alphavantage": {
      "command": "uv",
      "args": [
        "--directory",
        "<DIRECTORY-OF-CLONED-PROJECT>/alphavantage",
        "run",
        "alphavantage"
      ],
      "env": {
        "ALPHAVANTAGE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Note: Replace <DIRECTORY-OF-CLONED-PROJECT> with the actual directory path where you cloned the repository and YOUR_API_KEY_HERE with your Alpha Vantage API key.

Using the HTTP Server Mode with Claude Desktop

To run the server in Streamable HTTP mode with Claude Desktop:

{
  "mcpServers": {
    "alphavantage": {
      "command": "uv",
      "args": [
        "--directory",
        "<DIRECTORY-OF-CLONED-PROJECT>/alphavantage",
        "run",
        "alphavantage",
        "--server",
        "http",
        "--port",
        "8080"
      ],
      "env": {
        "ALPHAVANTAGE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Once configured, you can access Alpha Vantage stock market data directly through your Claude Desktop interface.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "alphavantage" '{"command":"uv","args":["--directory","<DIRECTORY-OF-CLONED-PROJECT>/alphavantage","run","alphavantage"],"env":{"ALPHAVANTAGE_API_KEY":"YOUR_API_KEY_HERE"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

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.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "alphavantage": {
            "command": "uv",
            "args": [
                "--directory",
                "<DIRECTORY-OF-CLONED-PROJECT>/alphavantage",
                "run",
                "alphavantage"
            ],
            "env": {
                "ALPHAVANTAGE_API_KEY": "YOUR_API_KEY_HERE"
            }
        }
    }
}

Adding an MCP server to a project

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.

How to use the MCP server

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "alphavantage": {
            "command": "uv",
            "args": [
                "--directory",
                "<DIRECTORY-OF-CLONED-PROJECT>/alphavantage",
                "run",
                "alphavantage"
            ],
            "env": {
                "ALPHAVANTAGE_API_KEY": "YOUR_API_KEY_HERE"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
