atomachinskiy/holst-mcp ? reverse-engineered prompt

Build me an MCP server for Holst.so that Claude Code can use to read and edit whiteboards through the local Holst desktop app.

I want it to connect to a running Holst app on my machine, use the existing logged in session, and let me inspect boards, search text, and get a readable summary of a board. It should also be able to create and edit the common things I use on a whiteboard, like stickers, shapes, simple text, arrows, frames, and emoji stamps, plus move, resize, recolor, update text, and delete objects.

Please make it work in a way that changes sync back to Holst right away, since the app uses live collaborative data. If needed, look up the current docs online and iterate until it works with the latest Holst desktop version. Also include a simple way to start Holst with the right debug port so the MCP server can connect to it.
