Tldraw

npm version License: MIT

MCP (Model Context Protocol) server for managing local tldraw canvas files (.tldr).

What Makes This Different?

Existing tldraw MCP servers let AI draw on an in-memory canvas. This project is different — it reads, writes, and searches local .tldr files on disk, making tldraw a persistent visual scratchpad that AI agents can programmatically update.

Features

• 📖 Read — Load and parse .tldr files
• ✍️ Write — Create and update canvas files with validation
• 📋 List — Enumerate all .tldr files with metadata
• 🔍 Search — Full-text search across all canvases
• 🔷 Shape CRUD — Add, update, delete shapes programmatically

Installation

npm (recommended)

npx @talhaorak/tldraw-mcp

From source

git clone https://github.com/talhaorak/tldraw-mcp.git
cd tldraw-mcp
bun install
bun run start

Environment Variables

Variable	Default	Description
TLDRAW_DIR	~/.tldraw	Base directory for .tldr files

Tools

tldraw_read

Read a .tldr file and return its parsed content.

tldraw_read({ path: "notes.tldr" })

tldraw_write

Write or update a .tldr file (validates format).

tldraw_write({ 
  path: "notes.tldr",
  content: { /* tldraw file object */ }
})

tldraw_create

Create a new empty tldraw canvas.

tldraw_create({ path: "new-canvas.tldr", name: "My Canvas" })

tldraw_list

List all .tldr files with page/shape counts.

tldraw_list({ recursive: true })

tldraw_search

Search text content across all canvases.

tldraw_search({ query: "TODO", searchIn: "text" })

tldraw_get_shapes

Get all shapes from a file, optionally filtered by page.

tldraw_get_shapes({ path: "notes.tldr", pageId: "page:abc123" })

tldraw_add_shape

Add a new shape to a canvas.

tldraw_add_shape({
  path: "notes.tldr",
  shape: {
    type: "geo",
    x: 100,
    y: 100,
    props: {
      w: 200,
      h: 100,
      geo: "rectangle",
      color: "blue",
      fill: "semi"
    }
  }
})

tldraw_update_shape

Update properties of an existing shape.

tldraw_update_shape({
  path: "notes.tldr",
  shapeId: "shape:abc123",
  updates: { x: 200, props: { color: "red" } }
})

tldraw_delete_shape

Delete a shape from a canvas.

tldraw_delete_shape({
  path: "notes.tldr",
  shapeId: "shape:abc123"
})

Use Cases

• Visual scratchpad for AI agents — AI updates a canvas you can view in tldraw
• Diagram generation — Create flowcharts, architecture diagrams programmatically
• Note organization — Search and organize visual notes across multiple canvases
• Integration with tldraw desktop/VS Code — Files sync automatically

tldraw File Format

This server works with tldraw v2 format:

{
  "tldrawFileFormatVersion": 1,
  "schema": {
    "schemaVersion": 2,
    "sequences": { ... }
  },
  "records": [
    { "id": "document:document", "typeName": "document", ... },
    { "id": "page:xxx", "typeName": "page", ... },
    { "id": "shape:xxx", "typeName": "shape", "type": "geo", ... }
  ]
}

Development

# Install dependencies
bun install

# Run in development mode
bun run dev

# Type check
bun run typecheck

# Build for distribution
bun run build

# Run tests
bun test

Publishing

./scripts/publish.sh          # Auto-increment patch (0.1.0 → 0.1.1)
./scripts/publish.sh 0.2.0    # Use specific version
./scripts/publish.sh minor    # Bump minor (0.1.1 → 0.2.0)
./scripts/publish.sh major    # Bump major (0.2.0 → 1.0.0)

The script updates package.json, commits, tags, and pushes. GitHub Actions handles npm publish automatically via Trusted Publishers.

Security

• Path traversal prevention — Relative paths can't escape TLDRAW_DIR
• Format validation — All writes are validated against tldraw schema
• No network access — Purely local file operations
