Install

Needs uv. No API key.

Claude Code:

claude mcp add yfinance-ai -- uvx yfinance-ai@latest

VS Code:

code --add-mcp '{"name":"yfinance-ai","type":"stdio","command":"uvx","args":["yfinance-ai@latest"]}'

Claude Desktop, Cursor, Windsurf and other clients, in the client's MCP config file:

{

"mcpServers": { "yfinance-ai": { "command": "uvx", "args": [ "yfinance-ai@latest" ] } } }

@latest picks up new releases when the client starts. Without uv: pip install yfinance-ai, then use "command": "yfinance-ai" with no args.

Listed in the MCP Registry as io.github.lkcair/yfinance-ai. Every tool is read-only.

Agent frameworks

The server runs over stdio with uvx yfinance-ai@latest, so any framework with MCP support can load all its tools.

LangChain: pip install "langchain[mcp]" langchain-anthropic

import asyncio

from langchain.agents import create_agent from langchain.mcp import MCPAdapter

async def main(): config = {"mcpServers": {"yfinance-ai": { "command": "uvx", "args": ["yfinance-ai@latest"], }}} async with MCPAdapter(config) as adapter: tools = await adapter.list_tools() agent = create_agent("claude-sonnet-5", tools) result = await agent.ainvoke({"messages": [{"role": "user", "content": "What is Apple's P/E, and how does it compare with Microsoft and Google?"}]}) print(result"messages".content)

asyncio.run(main())

Google ADK: pip install "google-adk[mcp]"

from google.adk.agents import LlmAgent

from google.adk.tools.mcp_tool import McpToolset from google.adk.tools.mcp_tool.mcp_session_manager import StdioConnectionParams from mcp import StdioServerParameters
