Smart Drawio tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • generate_drawio

    Generate a complete, validated draw.io XML diagram from a text prompt using the server model configured via SMART_DRAWIO_* environment variables. Requires all four provider settings. An incomplete or invalid model response is an error. Does not open a browser or write files.

  • list_drawio_options

    List available chart types, themes, style packs, presets, text tools and drawing tricks. Use these IDs in other tools.

  • repair_drawio

    Conservatively repair missing closing XML tags, then validate the result. Returns XML only as an in-memory result; does not write files or change an editor.

  • style_drawio

    Apply a theme, style pack, preset toggles, text tool or drawing trick to uncompressed draw.io XML. Discover valid IDs with list_drawio_options. Returns a new document without changing an editor.

  • validate_drawio

    Validate uncompressed draw.io XML syntax and diagram structure without modifying it. JSON, compressed diagrams and malformed XML return diagnostics.

Install Smart Drawio in Claude Code, Cursor or VS Code

Runs npx -y @yunshenwuchuxun/smart-drawio-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Overview

smart-drawio-next is a diagram generation tool built with Next.js 16, embedded Draw.io, and streaming LLM APIs. It helps you:

  • Generate structured diagrams from natural language prompts
  • Upload reference images and convert them into editable diagram content
  • Fine-tune XML / JSON in Monaco Editor
  • Sync output directly into an embedded Draw.io canvas
  • Use post-processing tools to improve layout, connectors, styles, and annotations

The project includes multi-model configuration, workspace recovery, generation history, and notifications. It can be deployed as a personal tool or an internal team service.

Core Features

  • Streaming generation with support for continuing truncated outputs
  • Multimodal input with both text and image-based workflows
  • Code + canvas workflow for editing XML and previewing the result side by side
  • Post-processing toolchain for structure, text, connector, and style refinement
  • Multi-provider config management for OpenAI / Anthropic-compatible APIs
  • Local history with replay support for recent generations

Agent Skill and MCP

Version 0.1.0 is published. Choose the entry point that fits your workflow:

Install the Skill

Install the fixed release:

npx skills add https://github.com/yunshenwuchuxun/smart-drawio-next/tree/tools-v0.1.0/skills/smart-drawio

The Skill is distributed as GitHub files, with no separate npm package. npx skills runs the general Skills CLI, which downloads the Skill from the repository. Its Python 3 validator works offline without third-party dependencies; MCP is optional.

Example agent request:

Use $smart-drawio to create an original encoder–decoder Transformer diagram, save it as transformer.drawio, and check its connectors and labels.

Configure the MCP server

Use Node.js 20.9 or later and a client that supports local stdio MCP. For clients using mcpServers JSON:

Shortened. The full README is on GitHub.
