Run Command
npm run dev

Security Notes

The server primarily acts as an API proxy for Yahoo Finance, implementing a cookie and crumb authentication mechanism to access potentially unofficial APIs. Input is validated using Zod schemas for tool arguments, mitigating common injection risks. No 'eval' or other direct arbitrary code execution vectors are apparent in the provided source. The reliance on undocumented Yahoo Finance APIs, while common for this type of service, inherently carries risks of API changes or unexpected behavior, but this is a fragility risk rather than a direct code security vulnerability.
