yfinance-ai: Yahoo Finance — questions

Answers built from our own checks of this server.

Why is there no uptime for yfinance-ai: Yahoo Finance?

yfinance-ai: Yahoo Finance runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package yfinance-ai was installed 202 times last week.

How do I connect yfinance-ai: Yahoo Finance?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls yfinance-ai straight from pypi; nothing to host, nothing to sign up for.

How many people use yfinance-ai: Yahoo Finance?

The pypi package yfinance-ai was installed 202 times in the last week. Week over week that is -90%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is yfinance-ai: Yahoo Finance open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
