Claude Code (local)
claude mcp add alphavantage -- uvx marketdata-mcp-server YOUR_API_KEYPasses the key as a command-line argument, so it sits in plain text in your MCP config. Pin with marketdata-mcp-server==0.3.1 if you want a fixed version.
Alpha Vantage’s own MCP server. Each Alpha Vantage API function is exposed as a tool: quotes and daily/intraday time series, company overviews and financial statements, earnings, news sentiment, forex and crypto rates, US economic indicators (GDP, CPI, rates), and technical indicators such as SMA, RSI and MACD.
When to use it
- You want quick price history, fundamentals or macro series without writing API code.
- You’re building a screen or comparison and want the agent to fetch the inputs itself.
Before you install
Use the hosted OAuth connection where your client supports it, so the key isn’t stored in a
config file. The free key is rate-limited; heavy use needs a paid plan. The same repo publishes
marketdata-cli and an agent skill (global-stock-analysis) if you prefer a CLI to MCP.
Limits
Models make arithmetic and data errors, and free-tier data may be delayed or end-of-day. Check anything you act on against a second source. Not investment advice.
