MCP.Pizza Chef: finite-sample

Fifty tools ship, four fewer than the readme advertises, spanning regression, forecasting, clustering, significance testing, summaries, charts, and reading or writing spreadsheet files. Ask whether an A/B test result was real or what next quarter might look like, and the sums are genuinely run in R, with the chart appearing in your chat. The catch is setup: both R and Python have to be installed on your computer first. A ready-made hosted copy exists but turns away anyone without a pass the documentation never explains how to get.

✨ What Can RMCP Do?

rmcp FAQ

Do I need to install anything first?

Yes, and this is the real hurdle. Both R and Python must be on your computer, along with a set of R add-ons, before the tool can do any sums.

Can I skip all that and use the hosted version?

In practice, no. The hosted copy is running, but it refuses connections without a pass, and nowhere in the documentation does it say how to obtain one.

Can I use this to check whether my A/B test is significant?

Yes. Describe the two groups or point it at your file, and it runs the appropriate test and explains the result in words rather than symbols.

Does it need a key?

Not for the copy running on your own machine. Keys only come into it if you put the tool on a server and reach it over the internet.

Can it change files on my computer?

Yes. Alongside reading spreadsheets it can write them, and it can run R code, which it gates behind an approval step for anything using an unfamiliar add-on.

Which apps does it work in?

Claude Desktop with a short settings block. If you host it yourself it also plugs into web assistants that accept a remote address, including ChatGPT.

Is it still being maintained?

Very much so. The code was updated within the last few days, which makes it one of the most active projects of its kind.
