What it does

The server exposes Alpha Vantage API functions as MCP tools: daily and intraday price series, technical indicators such as RSI, company overviews and other market data. The agent calls a function by name with parameters such as a ticker. The recommended connection is remote over OAuth, where you enter the key on an authorization page. A local launch via uvx is also available.

Who it is for. For analysts and developers who want the agent to use market data instead of answering from memory.

Example request

Give me last week's daily prices for IBM and compute RSI

Limitations

Requires an Alpha Vantage key; the free key has request limits. The server only provides data and is not financial advice. The key-in-URL option is deprecated. Availability from Russia is unverified.

How to disable. Disconnect the connector in client settings or remove the alphavantage block from the MCP config.

README in short

The README opens with three connection options: remote OAuth, the deprecated key-in-URL and local via uvx. Step-by-step instructions follow for chat clients, agent platforms and IDEs, including Claude, ChatGPT, Azure AI Foundry and Hermes Agent. It gives a sample system prompt so the agent takes data from the server. MIT licensed.
