## Common questions

### What is the Smart Drawio MCP server?

Smart Drawio is an MCP server listed in the public MCP registry as io.github.yunshenwuchuxun/smart-drawio. Generate, validate, repair and style editable draw.io XML diagrams. This page covers its npm package (@yunshenwuchuxun/smart-drawio-mcp).

### Is the Smart Drawio MCP server safe to use?

Smart Drawio scores 71 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 23 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Smart Drawio MCP server expose?

Smart Drawio exposes 5 tools: list_drawio_options, validate_drawio, repair_drawio, style_drawio, generate_drawio. Their descriptions and schemas cost roughly 339 tokens of context every time the server is loaded.

### Is the Smart Drawio MCP server still maintained?

Smart Drawio is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Smart Drawio MCP server under?

Smart Drawio declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
