Alpha Vantage MCP Server

A Model Context Protocol (MCP) server that exposes various Alpha Vantage API endpoints as MCP tools, providing access to financial data including core stocks, options, intelligence, fundamental data, and technical indicators. This server simplifies integrating Alpha Vantage data into MCP-compatible agents and systems.

Prerequisites

• Node.js (v18 or later recommended)
• npm (comes with Node.js)
• Alpha Vantage API key
• (Optional) MCP-compatible client or runner (e.g., VSCode extension, CLI)

Setup

1. Clone the repository or ensure you are in the project directory.

2. Install dependencies:

   npm install
   

3. Configuration:

   • Obtain an Alpha Vantage API key from https://www.alphavantage.co/.
   • Configure the ALPHAVANTAGE_API_KEY environment variable via your MCP runner's settings. This is the recommended method for seamless integration with the MCP client. Avoid using .env files for this purpose when running via an MCP runner.

Building and Running

1. Build the server:

   npm run build
   

   This will create a build directory with the compiled JavaScript code.

2. Run the server:

   npm run start
   

   or directly:

   node build/index.js
   

3. Via MCP runner: Configure your MCP client to run the server using stdio transport. Example MCP settings entry (adjust /path/to/mcp-alphavantage to your actual path and replace YOUR_API_KEY_HERE with your actual key):

   "alphavantage": {
     "transportType": "stdio",
     "command": "node",
     "args": [
       "/path/to/mcp-alphavantage/build/index.js"
     ],
     "env": {
       "ALPHAVANTAGE_API_KEY": "YOUR_API_KEY_HERE"
     }
     // ... other optional settings ...
   }
   

Available Tools

The server exposes Alpha Vantage API endpoints as distinct MCP tools, categorized by function:

• Core Stocks
• Options Data
• Alpha Intelligence
• Fundamental Data
• Technical Indicators
• Forex
• Cryptocurrencies
• Commodities
• Economic Indicators

Detailed input schemas and descriptions for each tool are automatically discoverable by MCP agents connecting to the server via introspection.

Caching

The server implements an in-memory Least Recently Used (LRU) cache for tool responses. This helps reduce redundant calls to the Alpha Vantage API, improving performance and adhering to rate limits.

• Mechanism: The cache stores responses based on the tool name and input parameters.
• Configurable TTLs: Each tool has a configurable Time To Live (TTL) for its cached data, defined in src/cacheConfig.ts. This allows for different caching durations based on the update frequency of the data provided by each Alpha Vantage endpoint.
