financial-datasets/mcp-server — reverse-engineered prompt

Build me a small Python MCP server that lets Claude Desktop or another AI assistant pull stock market and crypto data from the Financial Datasets API.

I want it to expose tools for getting a company’s income statements, balance sheets, cash flow statements, current stock price, historical stock prices, and recent company news. It should also support crypto, including listing available crypto tickers, getting current crypto prices, and getting historical crypto prices.

Please make it simple to run locally. Use an environment variable for the Financial Datasets API key, include an example env file, and make sure the server starts cleanly with uv. Add clear README instructions for installing dependencies, adding the API key, running the server, and connecting it to Claude Desktop.

Keep the code straightforward and reliable. Handle missing inputs or API errors gracefully so Claude gets useful error messages instead of crashing. Look up the current MCP docs online if you need to.
