Common questions

Is yfinance-ai: Yahoo Finance safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (5.0.5) reached the registry 18 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

🚀 Thousands of downloads on ClawHub and OpenWebUI

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

root_agent = LlmAgent( model="gemini-flash-latest", name="yfinance_ai", instruction="Answer with the yfinance-ai tools.", tools=[McpToolset(connection_params=StdioConnectionParams( server_params=StdioServerParameters(command="uvx", args=["yfinance-ai@latest"]), timeout=60, ))], )

Strands Agents: pip install strands-agents

from mcp import stdio_client, StdioServerParameters

from strands import Agent from strands.tools.mcp import MCPClient

yfinance_ai = MCPClient(lambda: stdio_client(StdioServerParameters( command="uvx", args=["yfinance-ai@latest"], ))) agent = Agent(tools=[yfinance_ai]) agent("What is Apple's P/E, and how does it compare with Microsoft and Google?")
