Damp spot under boiler. What is leaking?

I found this damp spot under the spigot on the bottom corner of my boiler. It looks like it is very slowly leaking. I'm wondering, What exactly is leaking and what do I need to have replaced?
Weill McLain steam boiler. One pipe steam. Boiler was installed in 2002, but I just moved into the house last year
thank you!

It's just the factory valve to drain or blow-down the mud out of the boiler. Has someone been blowing it down monthly? (LWCO too.) If not, you probably want an experienced tech to do it (including unjamming and re-washering/replacing) while you watch.
The drip is not a huge problem but if "mud" (iron oxide and other crud) builds up in the boiler the bottom sheet will melt, which is dangerous and expensive and bad.
There's a burner-service company sticker. I'd call them first.2 -

A quick fix is to put a cap over the drain, like this:

I put those caps on anything with hose thread as a matter of course, make it a two-step process for anyone to accidentally flood the house.
You do want to replace that valve eventually. Usually what happens is once they start leaking if you ever have to open it the leaking gets much worse when you close it.1 -
