Yahoo Finance MCP server

Yahoo Finance MCP Server 📈

Real-time stock market data for Claude Desktop and any MCP-compatible client, powered by Yahoo Finance. Get quotes, historical prices, company profiles, financial statements, analyst ratings, and multi-stock comparisons, all from natural language.

npm package: yahoo-finance-mcp-server  ·  GitHub repo: danishashko/yahoo-finance-mcp. The repo name is shorter than the package name; both refer to this project.

🎯 What You Get

• 📊 Real-time stock quotes with full market data
• 📈 Historical prices (OHLCV) with summary statistics
• 🏢 Company profiles, officers, and key statistics
• 💰 Financial statements (income, balance sheet, cash flow)
• 🎯 Analyst ratings, price targets, and the recent recommendation trend
• ⚖️ Multi-stock comparisons side by side
• 📰 Latest financial news per ticker
• 🧾 Options chains (calls/puts, strikes, IV, open interest)
• 🏦 Ownership data — institutional, mutual fund, and insider activity
• 💵 Dividend & split history
• 🔮 Forward analyst estimates (price targets, EPS/revenue, growth)
• 🔎 Symbol search by company name or keyword

Every tool returns human-readable markdown by default, or structured JSON on request (response_format: "json"). Requests share a single browser-impersonating HTTP session to reduce Yahoo Finance rate-limiting.

🚀 Quick Start

Add this to your Claude Desktop config and restart Claude:

• macOS: ~/Library/Application Support/Claude/claudedesktopconfig.json
• Windows: %APPDATA%\Claude\claudedesktopconfig.json

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "npx",
      "args": ["-y", "yahoo-finance-mcp-server"]
    }
  }
}

That is it. On first launch the npx wrapper creates an isolated Python environment and installs the dependencies for you (a one-time step that can take a minute). You only need Python 3.10+ and Node.js 16+ on your machine.

Prefer a global install?

npm install -g yahoo-finance-mcp-server

{
  "mcpServers": {
    "yahoo-finance": {
      "command": "yahoo-finance-mcp-server"
    }
  }
}

🌐 HTTP mode (n8n, remote agents, anything that connects to a URL)

Some clients spawn an MCP server as a child process and talk to it over stdio; others only take a URL. n8n's MCP Client Tool node is the second kind - it offers HTTP Streamable and SSE and no way to launch a command - so stdio alone puts the server out of reach.

--http serves the same 13 tools over Streamable HTTP at /mcp:

npx -y yahoo-finance-mcp-server --http
# -> http://127.0.0.1:8000/mcp

No authentication is added, so keep it on an interface you trust.

Reaching it from a container

n8n in Docker is not on your loopback interface, so bind wider and use the host alias:

npx -y yahoo-finance-mcp-server --http --host 0.0.0.0 --port 8931
