# Yahoo Finance MCP Backend Upgraded. 25 Tickers in One Request, Answers in Seconds, Clear Errors Instead of Slow Failures.

Getting slow response on TigZig's Yahoo Finance MCP? Errors? Backend upgraded ... shiny new. You can now send up to 25 tickers in one request, it comes back in seconds instead of stalling, and if one name is bad or slow it returns a short note while the rest still comes through, with a clear message instead of a slow failure.

If you use the Yahoo Finance MCP on Claude, ChatGPT, LM Studio or anything else, it is vastly improved now.

You get an error on any TigZig apps ... it will pop up on my monitoring. I will hunt it down, find the root cause .. and if the issue is on my end, I'll fix it.
