MCP Server for Alpha Vantage API (@missionsquad/avantage)

This project provides a Model Context Protocol (MCP) server that wraps the @missionsquad/avantage library, exposing Alpha Vantage API functionalities as tools for Language Learning Models (LLMs).

Overview

This server allows LLMs to interact with the Alpha Vantage API to retrieve financial data, including:

• Core Stock Data (Time Series, Quotes, Search)
• Fundamental Data (Company Overview, Financials, Calendars)
• Forex (FX) Data
• Cryptocurrency Data
• Commodities Data
• Economic Indicators
• Technical Indicators
• Alpha Intelligence (News, Sentiments, etc.)
• Options Data (Premium)

It leverages the @missionsquad/avantage TypeScript library and follows the architecture of the generic MCP server template, including multi-user API key handling and resource management for AVantage client instances.

Key Features:

• Comprehensive Coverage: Implements MCP tools for nearly all functions available in the @missionsquad/avantage library.
• Multi-User Support: Handles Alpha Vantage API keys securely via extraArgs (preferred) or fallback to environment variables.
• Resource Management: Efficiently manages AVantage client instances using the ResourceManager.
• Strongly Typed: Built with TypeScript, leveraging types from @missionsquad/avantage and Zod schemas for tool parameters.
• Standard MCP Interface: Uses @missionsquad/fastmcp for MCP communication.

Getting Started

Prerequisites

• Node.js v20 or later
• npm or yarn
• An Alpha Vantage API Key (Get one here)

Setup

1. Clone or Copy: Clone this repository or copy the files.

   git clone <repository-url> mcp-avantage-server
   cd mcp-avantage-server
   

2. Install Dependencies:

   npm install
   # or
   yarn install
   

3. Configure Environment:
   • Copy .env.example to .env.
   • Edit .env and set API_KEY to your Alpha Vantage API key.
   • Optionally set AV_PREMIUM=true if you have a premium subscription.
   • Adjust LOG_LEVEL or RESOURCE_CLEANUP_INTERVAL if needed.
4. Build the Project:

   npm run build
   # or
   yarn build
   

5. Start the Server:

   npm start
   # or
   yarn start
   

   The server will listen for MCP requests on stdio.

Authentication

The server uses the standard multi-user token handling pattern:

1. extraArgs.apiKey (Recommended): Pass the user-specific Alpha Vantage API key in the apiKey field of the extraArgs object during the MCP call_tool request. This key is not part of the tool’s schema.
2. .env Fallback: If extraArgs.apiKey is not provided, the server uses the API_KEY value from the .env file.

Available Tools

This server exposes numerous tools corresponding to the methods in the @missionsquad/avantage library. Tools are generally named module_method (e.g., coreStock_intraday, fundamentalData_companyOverview).

Refer to the Alpha Vantage documentation and the @missionsquad/avantage library’s types (src/types/* within the library) for details on parameters and return structures.
