本地无限画布的 MCP Server,让 AI 客户端(Claude Desktop / Cursor 等)通过 Model Context Protocol 直接读写本地画布数据。

三个模块,各司其职:
| 模块 | 职责 | 技术栈 |
|---|---|---|
| mcp-server | MCP 协议通信,AI 调用工具读写画布 | Node.js ESM, @modelcontextprotocol/sdk |
| web-server | HTTP 可视化,浏览器实时查看/编辑画布 | Node.js 原生 http 模块(零依赖) |
| client | 前端编辑器(可选),tldraw 专业图形界面 | React 18, tldraw 5, Vite |
安装
# 克隆项目
git clone <repo-url>
cd timeverse-InfCanvas-mcp
# 安装 MCP Server 依赖
cd mcp-server && npm install
# (可选)构建前端编辑器
cd ../client && npm install && npm run build
在 AI 客户端中配置
MCP Server 通过 stdio 协议与 AI 客户端通信,配置时指向 mcp-server/server.mjs。
Claude Desktop
编辑 claude_desktop_config.json:
{
"mcpServers": {
"infcanvas": {
"command": "node",
"args": ["D:/path/to/timeverse-InfCanvas-mcp/mcp-server/server.mjs"],
"env": {
"INF_CANVAS_DIR": "D:/path/to/your-project",
"REPLICATE_API_KEY": "r-xxxxx"
}
}
}
}
Cursor
编辑 .cursor/mcp.json:
{
"mcpServers": {
"infcanvas": {
"command": "node",
"args": ["D:/path/to/timeverse-InfCanvas-mcp/mcp-server/server.mjs"]
}
}
}
自研客户端
支持以下方式集成:
方式一:JSON 配置(适用于支持 MCP 配置文件的客户端)
{
"mcpServers": {
"infcanvas": {
"command": "node",
"args": ["D:/path/to/timeverse-InfCanvas-mcp/mcp-server/server.mjs"],
"env": {
"INF_CANVAS_DIR": "D:/my-project"
}
}
}
}
方式二:通过 npx(无需本地安装,自动从 npm 拉取)
{
"mcpServers": {
"infcanvas": {
"command": "npx",
"args": ["-y", "timeverse-infcanvas-mcp"],
"env": {
"INF_CANVAS_DIR": "D:/my-project"
}
}
}
}
注意:
timeverse-infcanvas-mcp尚未发布到 npm,发布后方可使用此方式。
方式三:代码中通过 stdio 启动子进程
const { spawn } = require('node:child_process')
const cp = spawn('node', ['D:/path/to/mcp-server/server.mjs'], {
env: { ...process.env, INF_CANVAS_DIR: 'D:/my-project' },
stdio: ['pipe', 'pipe', 'pipe'],
})
// 通过 stdin/stdout 收发 JSON-RPC 2.0 消息
暴露的 MCP 工具
所有数据操作工具都需要 projectDir 参数(指定项目目录,在其下创建 canvas/ 文件夹):
| 工具 | 用途 | 必填参数 |
|---|---|---|
get_canvas_snapshot |
获取画布全量数据 | projectDir |
get_selection |
读取当前用户选区 | projectDir |
list_pages |
列出所有页面 | projectDir |
create_page |
新建页面 | projectDir |
switch_page |
切换当前页面 | projectDir, pageId |
create_ai_image_holder |
创建 AI 图片占位框 | projectDir |
insert_image |
插入图片(本地路径或 URL) | projectDir, sourcePath |
fill_ai_holder |
把已有 asset 填入占位框 | projectDir, holderId, assetId |
update_shape |
更新 shape 位置/属性 | projectDir, shapeId |
update_shape_status |
流式更新生成状态与进度 | projectDir, shapeId, status |
delete_shapes |
删除多个 shape | projectDir, shapeIds |
generate_image |
大模型生图并直接填入画布 | projectDir, prompt |
start_web_server |
启动 HTTP 可视化服务(无 projectDir 也可调用) | — |
start_web_server
AI 调用此工具后,会在本地启动 HTTP 服务,打开浏览器即可实时查看/操作画布:
{
"name": "start_web_server",
"arguments": { "port": 3000 }
}
返回 { "url": "http://localhost:3000", "status": "started" }。重复调用不会重复启动,浏览器打开 http://localhost:3000 即可查看画布。
手动启动
# MCP Server(stdio 交互,通常由 AI 客户端自动拉起)
npm start
# Web 可视化服务
npm run web
# 浏览器打开 http://localhost:3000
# 前端开发模式
npm run dev:client
# 构建前端
npm run build:client
环境变量
| 变量 | 用途 | 必填 |
|---|---|---|
INF_CANVAS_DIR |
兜底项目目录(不填则每次调用传 projectDir) |
否 |
OPENAI_API_KEY |
OpenAI API Key(DALL-E 3 生图) | 按需 |
OPENAI_API_ENDPOINT |
OpenAI 端点,默认 https://api.openai.com/v1 |
否 |
REPLICATE_API_KEY |
Replicate API Token(Flux / SDXL 生图) | 按需 |
CUSTOM_API_ENDPOINT |
自研模型 HTTP 端点 | 按需 |
CUSTOM_API_KEY |
自研模型 API Key | 按需 |
大模型生图
支持的模型(通过环境变量路由):
| model | 依赖 |
|---|---|
dall-e-3 |
OPENAI_API_KEY |
flux-schnell |
REPLICATE_API_KEY |
sdxl |
REPLICATE_API_KEY |
custom |
CUSTOM_API_ENDPOINT + CUSTOM_API_KEY |
工具参数中传 endpoint 和 apiKey 可临时覆盖环境变量。
测试
cd mcp-server
node test.mjs
冒烟测试会验证 MCP 协议通信、数据隔离、工具调用等核心功能。
画布数据格式
<project>/canvas/
├── canvas.json 画布索引(页面、shape 列表、资源)
├── selection.json 当前选区
