MateUI puts agents on the design canvas

Field notes

Connection starts in MateUI’s Agents settings: it runs a local MCP server and says it writes the selected agent’s configuration, avoiding manual JSON edits. Once connected, an agent works in the open file; the page also describes layer selection with ⌘K, comment mentions that apply a fix in place, and a design check for contrast, spacing, and hard-coded colours. The 120-fps figure is presented for a 221k-layer file, not independently substantiated in the extracted material.
