How minimal is this MCP server compared to others?

It provides a focused set of stock data retrieval tools without extra features, making it simple to understand, configure, and maintain.

Can I combine this with other MCP servers?

Yes. MCP clients support multi-server configurations, so you can run this alongside execution-capable or analysis-focused servers.

What Python version is required?

Check the repository for specific version requirements. Most yfinance-based MCP servers require Python 3.8 or higher.

Yahoo Finance MCP (narumiruna)

Yahoo Finance MCP (narumiruna) is a minimal MCP server focused on stock data retrieval through the yfinance library. It takes a deliberately simple approach, providing a clean set of tools for querying Yahoo Finance data without additional complexity. This makes it one of the more straightforward options for users who want basic stock data access in their MCP agent workflows.

The server exposes tools for retrieving stock prices, historical data, and basic financial information from Yahoo Finance. Its minimalist design means fewer moving parts and less configuration overhead. For users who primarily need to look up prices, pull historical charts, or check key financial metrics, this server covers the essentials without unnecessary feature bloat.

Installation and setup follow standard patterns for Python-based MCP servers. Users install the required dependencies, configure the server in their MCP client, and begin making tool calls. No API keys are needed since it relies on the yfinance library’s access to Yahoo Finance data. The server is strictly read-only and does not support trade execution. For users who need a broader feature set, it can serve as a lightweight data layer alongside more specialized MCP servers for analysis or execution.
