How to install

Runs on your machine from its package; the steps are below.

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 — From the README · 1 of 4

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

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

Add it to your agent

# Claude Code
claude mcp add whiteboard --scope user -- npx -y @ansuman-shukla/whiteboard-mcp

# Codex CLI
codex mcp add whiteboard -- npx -y @ansuman-shukla/whiteboard-mcp

# Gemini CLI
gemini mcp add --scope user whiteboard npx -y @ansuman-shukla/whiteboard-mcp

# Devin CLI
devin mcp add whiteboard --scope user -- npx -y @ansuman-shukla/whiteboard-mcp

# VS Code
code --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.
