What is the Whiteboard MCP MCP server?

whiteboard-mcp is a simple whiteboard web application, providing a convenient way for displaying Chatbot/LLM's output. Exposed over MCP by the whiteboard mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

  • Web whiteboard — — Browser UI to show content pushed by agents or other clients; good for demos and side-by-side LLM output
  • Any screen — — Open the board URL in a browser on any monitor, projector, or device on your network
  • Dual MCP transports — — Streamable HTTP at /mcp and SSE at /sse for clients that only support one style
  • REST API — — GET/POST /api/content for non-MCP integrations; history list/restore/delete under /api/history
  • History — — Server-side history of updates; reopen a past version from the history UI (and via the history API)
  • Export — — Save the current view as HTML or Markdown from the menu; Print / PDF (browser print-to-PDF) when the board shows HTML or Markdown

Adding it to your client

whiteboard-mcp on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Its toolset

Everything the assistant can do here goes through one of these:

  • update_whiteboard_url — Set the board to load a URL (url)
  • update_whiteboard_html — Render raw HTML (html)
  • update_whiteboard_markdown — Render Markdown (markdown)

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the whiteboard mcp mcp server does with a few real requests.

When to reach for it

Plenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Whiteboard MCP's toolset — update_whiteboard_url, update_whiteboard_html, update_whiteboard_markdown — is a fair guide to whether it matches your workflow. It is maintained by mikewei; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects Whiteboard MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (update_whiteboard_url, update_whiteboard_html, update_whiteboard_markdown) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Whiteboard MCP directly.
