Hi — noticed StockSense-AI fetches stock data via yfinance inside the LangGraph pipeline, which ties the data layer tightly to the yfinance client.
langchain-toolstem wraps stock snapshots and company metrics as proper LangChain tools via a hosted MCP server — so your agent can call getStockSnapshot and compareCompanies as structured tool calls rather than raw yfinance fetches. Billing is x402 USDC micropayments (~$0.005/call), no subscription needed.
from langchain_toolstem import create_finance_tools
tools = await create_finance_tools()
# Plug into your existing create_react_agent or LangGraph node
