No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
The tool is free and requires no signup. It computes both the Graham number and the margin of safety if the current price is entered. The Graham number formula is the square root of 22.5 times earnings per share times book value per share.
The formula only makes sense for profitable companies with positive earnings and positive book value. Edge Thirteen screens roughly 5,000 U.S. stocks every week and sends the genuine value picks for $13 per month.
