append_frame_html

MCP tool from Doop by kgoedecke

Stream a design in chunks (start=true first, done=true last) — viewers watch it build up

How to use it

Project documentation lists append_frame_html for the Doop MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Install Doop

$claude mcp add --transport http doop http://localhost:4300/mcp
