I'll be writing a blog post about this, but at Mozi we just open-sourced a tool I wrote that I've been using a lot: https://github.com/mozi-app/mermAId . It's a Mermaid live editor / MCP server that is made to interact with LLM agents while planning. The agent can push and pull Mermaid diagrams from the editor. The editor has vim bindings support if you want to use them. On macOS it's a native app, on Linux and Windows it runs a server and opens the UI in the browser. There is an accompanying CLI script for those who prefer that over MCP. The details are all in the README.
