Unmerge MCP Server

What it is

Unmerge takes a flat image (a poster, screenshot or illustration) and splits it into separate transparent PNG layers that you can edit individually.

The MCP server lets an assistant start a split, fetch the resulting layers, unlock them and check your credit balance. Processing is paid with Unmerge credits. It is listed in the official MCP Registry as app.unmerge/unmerge.
