概览

AI 生成的概览

本地 Excalidraw 白板服务器，让编码助手在聊天旁的白板上实时画图，并看到你画回去的内容。

可以做什么
  • 在聊天旁的实时 Excalidraw 白板上绘制图表
  • 读取白板内容，让助手看到用户画了什么
  • 以本地进程方式运行，作为与编码会话配合的省 token 白板
  • 附带技能说明，教助手何时适合画图
适用场景
适合在工作时让编码助手随手画架构图、流程图或草图，并对你在同一块白板上的修改作出回应。更适合桌面端助手环境，而非网页聊天。
运行要求
以 stdio 本地进程运行，通过 npx 从 npm 包安装；需要 Node.js 以及桌面端 MCP 客户端，例如 Claude Code、Codex CLI、Gemini CLI、Cursor、Claude Desktop、Windsurf、VS Code 或 OpenCode。未声明认证、环境变量或请求头。
安装前请注意
白板是助手可读写的本地实时界面，画在上面的内容对助手可见，依赖前请先查看它画了什么。未要求任何凭据或付款。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Whiteboard MCP，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

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

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 →
