README 摘要

# Excalidraw MCP App Server MCP server that streams hand-drawn Excalidraw diagrams with smooth viewport camera control and interactive fullscreen editing.  ## Install Works with any client that supports [MCP Apps](https://modelcontextprotocol.io/docs/extensions/apps) — Claude, ChatGPT, VS Code, Goose, and others. If something doesn't work, please [open an issue](https://github.com/antonpk1/excalidraw-mcp-app/issues). ### Remote (recommended) ### `https://mcp.excalidraw.com` For apps that don't yet have an official integration, you can add a custom MCP / connector (naming can vary between apps). ### Local **Option A: Download Extension** 1. Download `excalidraw-mcp-app.mcpb` from [Releases](https://github.com/antonpk1/excalidraw-mcp-app/releases) 2. Double-click to install in Claude Desktop **Option B: Build from Source** ```bash git clone https://github.com/excalidraw/excalidraw-mcp.git cd excalidraw-mcp-app pnpm install && pnpm run build ``` Add to `~/Library/Application Support/Claude/claude_desktop_config.json`: ```json { "mcpServers": { "excalidraw": { "command": "node", "args": ["/path/to/excalidraw-mcp-app/dist/index.js", "--stdio"] } } } ``` Restart Claude Desktop. ## Usage Example prompts: - "Draw a cute cat using excalidraw" - "Draw an architecture diagram showing a user connecting to an API server which talks to a database" ## What are MCP Apps and how can I build one? Text responses can only go so far. Sometimes users need to interact with data, not just read about it. [MCP Apps](https://github.com/modelcontextprotocol/ext-apps/) is an official Model Context Protocol extension that lets servers return interactive HTML interfaces (data visualizations, forms, dashboards) that render directly in the chat. - **Getting started for humans**: [documentation](https://modelcontextprotocol.io/docs/extensions/apps) - **Getting started for AIs**: [skill](https://github.com/modelcontextprotocol/ext-apps/blob/main/plugins/mcp-apps/skills/create-mcp-app/SKILL.md) ## Contributing PRs welcome!
