Yahoo Finance MCP (leoncuhk)

Yahoo Finance MCP (leoncuhk) is an MCP server that exposes Yahoo Finance data to MCP-compatible agents. Built on the yfinance library, it provides structured access to stock quotes, historical price data, financial statements, and company fundamentals. This allows agents to retrieve equity market data through typed tool calls without needing to interact with Yahoo Finance directly.

The server covers common stock research needs including current and historical pricing, income statements, balance sheets, and key financial ratios. These capabilities make it useful for research and screening workflows where an agent needs to gather fundamental or price data across multiple securities. The structured MCP format ensures clean data handoff between the server and the consuming agent.

Setup involves configuring the server in your MCP client environment and ensuring the required Python dependencies are installed. Because it relies on Yahoo Finance as a data source, users should be aware of potential rate limits and the unofficial nature of the yfinance library’s data access. The server is read-only — it retrieves data but does not execute trades — making it a low-risk addition to any agent workflow focused on stock analysis and research.
