Shameless plug,

I created an opensource unofficial mcp/skill/cli here git@github.com:allan-simon/figma-kiwi-protocol.git

Its based on a reverse engineering of the kiwi protocol and it works for read/write , comments etc. and it does not require anything except a cookie session ( I usually automate this part by having a isolated chrome with CDP activated)

I created sometimes ago because I had to work with some customers who didnt want to pay for a full seat for my account so the official mcp was not possible at all.
