figma
Signing in is what switches these skills on. Until it happens they are instructions for a tool that is not there.
It is also the decision with consequences: this connection can change a file, not only read one.
What it reads.
the frame or layer whose link is pasted in
the components, variables and styles that frame uses
a picture of the selection, to compare against
the animation set on a layer
a map of a large selection, when the whole thing is too big to return at once
What it changes.
creates and edits frames, components, variables and auto layout inside a file
opens a new blank Figma, FigJam or Slides file
draws diagrams and whole boards in FigJam
sets and edits the animation on a layer
It reaches the files the signed-in account already reaches, and nothing outside Figma.
It works from a link to a frame in a real Figma file. The client cannot open that link itself; it takes the frame's id out of it and asks Figma for that one object.
Its tools, and the sign-in it asks for, are set out on their own page: Figma MCP server
