Yahoo Finance MCP Server — questions

Answers built from our own checks of this server.

What can Yahoo Finance MCP Server do?

It exposes 3 tools, read directly from the server on our last check. Among them: compare_stocks, get_multiple_quotes, get_stock_quote. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Yahoo Finance MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 90 ms. The bar chart above shows every period we have measured.

How do I connect Yahoo Finance MCP Server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Yahoo Finance MCP Server need an API key?

Yes. Every time we knock, Yahoo Finance MCP Server answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Yahoo Finance MCP Server?

It answers our handshake in 90 ms on average, which is faster than 94% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
