alpha_vantage_mcp — Claude Code MCP server: what it does, setup
Connects coding assistants to Alpha Vantage market data for equities and currencies. Useful when an agent needs actual price feeds directly inside development chats.
claude mcp add --transport sse alpha-vantage-mcp https://mcp.alphavantage.co/mcpWhat alpha_vantage_mcp does
The server exposes Alpha Vantage endpoints through the Model Context Protocol. Clients discover functions via tools/list. The model then calls them to retrieve equity quotes or macro metrics.
You can point your agent to https://mcp.alphavantage.co/mcp over SSE or launch it locally using uvx marketdata-mcp-server. Without an Alpha Vantage API key, queries fail: the key must be authorized in the browser or supplied in the terminal.
What it helps with
- fetch equity quotes and stock history inside chats
- query foreign exchange rates without third-party browser tabs
- retrieve macroeconomic metrics for financial code testing
- inspect cryptocurrency prices during development
Example prompts for the agent
- Check the latest stock price and trading volume for Apple
- Look up the exchange rate between EUR and USD right now
- Retrieve recent inflation statistics via Alpha Vantage
