概覽

AI 產生的概覽

本機 Excalidraw 白板伺服器，讓編碼助理在對話旁的白板上即時畫圖，並看到你畫回去的內容。

可以做什麼
  • 在對話旁的即時 Excalidraw 白板上繪製圖表
  • 讀取白板內容，讓助理看到使用者畫了什麼
  • 以本機程序方式執行，作為搭配編碼工作階段的省 token 白板
  • 附帶技能說明，教助理何時適合畫圖
適用情境
適合在工作時讓編碼助理順手畫架構圖、流程圖或草圖，並對你在同一塊白板上的修改做出回應。較適合桌面端助理環境，而非網頁對話。
執行需求
以 stdio 本機程序執行，透過 npx 從 npm 套件安裝；需要 Node.js 以及桌面端 MCP 用戶端，例如 Claude Code、Codex CLI、Gemini CLI、Cursor、Claude Desktop、Windsurf、VS Code 或 OpenCode。未宣告驗證、環境變數或標頭。
安裝前請注意
白板是助理可讀寫的本機即時介面，畫在上面的內容對助理可見，依賴前請先查看它畫了什麼。未要求任何憑證或付款。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Whiteboard MCP，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

[Whiteboard MCP: a live whiteboard your coding agent draws on. You draw back.]

https://github.com/user-attachments/assets/197876d8-5620-4c1b-9bc3-332e0e7d5622

Whiteboard MCP is a free and extremely token-efficient whiteboard MCP that runs locally. Your coding agent draws diagrams on a live board beside the chat, and sees what you draw back.

One command install for every agent ↓


Features

[Why Whiteboard MCP: draws step by step, sees what you draw, right beside the chat, remembers boards, local and private, tiny (one runtime dependency, about 7 KB of tool schema per turn).]

What you can do with it

Understand an architecture

[An agent chat beside a live whiteboard: the agent draws a checkout architecture step by step, the human drags Postgres, circles the queue and sends a note asking what happens if the email worker is down, and the agent reads the changes and adds a dead-letter queue]

Explain a flow

[The agent draws a login flow step by step, highlights the parts it explains, then answers a note left by the human]

Play games

[Playing Dots and Boxes with a coding agent: the human draws a line on the board, the agent sees the move and plays back, until red wins 12 to 4]

Make something

[An agent paints the Mona Lisa on the board, then refines the sky, hair and dress with pencil strokes]

Quick start

[Get started in a minute: 1. Add it to your agent with one npx line. 2. Start a new chat. 3. Ask for a drawing.]

Add it to your agent

sh
# Claude Codeclaude mcp add whiteboard --scope user -- npx -y @ansuman-shukla/whiteboard-mcp
# Codex CLIcodex mcp add whiteboard -- npx -y @ansuman-shukla/whiteboard-mcp
# Gemini CLIgemini mcp add --scope user whiteboard npx -y @ansuman-shukla/whiteboard-mcp
# Devin CLIdevin mcp add whiteboard --scope user -- npx -y @ansuman-shukla/whiteboard-mcp
# VS Codecode --add-mcp '{"name":"whiteboard","command":"npx","args":["-y","@ansuman-shukla/whiteboard-mcp"]}'

Cursor, Claude Desktop, Windsurf and other JSON configs (~/.cursor/mcp.json, Claude Desktop's config, …):

json
{ "mcpServers": { "whiteboard": { "command": "npx", "args": ["-y", "@ansuman-shukla/whiteboard-mcp"] } } }

OpenCode (opencode.json):

json
{ "mcp": { "whiteboard": { "type": "local", "command": ["npx", "-y", "@ansuman-shukla/whiteboard-mcp"] } } }

Agents without MCP, project-level configs and more: client setup. The bundled skill teaches the agent when a drawing helps.

Whiteboard MCP vs Excalidraw MCP

[Whiteboard MCP vs Excalidraw MCP: Whiteboard MCP sees what you draw back as a short list of changes, screenshots its own board, edits one shape in place, keeps boards beyond the chat, works in any MCP client plus a CLI, and converts Mermaid. Excalidraw MCP has animated camera moves and zero install.]

Want a quick one-off diagram inside Claude or ChatGPT on the web? Excalidraw MCP is great for that. Full comparison →
