Drawio MCP Server
Diagramming capabilities for AI agents using Draw.io native tools.
Data last scanned last week · Reviewed last month
Overview
The Draw.io MCP server enables AI agents to programmatically create, modify, and inspect diagrams directly through the Draw.io engine. It supports complex operations such as layer management, edge geometry control with waypoint routing, and parent-child grouping for nested shapes. The server facilitates multi-document and multi-page workflows, allowing agents to target specific diagrams or pages for editing. Built to integrate with any MCP-compliant client, the server includes features for importing and exporting diagrams in XML, SVG, and PNG formats. It also supports Mermaid diagram expansion and provides auto-discovery for major cloud and network stencils. The system utilizes per-document FIFO serialization to manage concurrent operations when multiple agents interact with the same files.
Our verdict
With a security score of 50/100, this server is classified as high risk. This rating reflects the fact that its authentication methods, OAuth support, and read-only mode capabilities remain unreviewed. As a community-maintained project that lacks an official vendor relationship, users should exercise caution when deploying it in sensitive environments until the security posture of its interaction layer is more clearly defined.
- Supports Mermaid diagram import and expansion
- Auto-discovers cloud and network stencils at runtime
- Zero direct dependencies reduce supply-chain surface
- Per-document FIFO serialization for multi-agent safety
- Security score of 50/100 indicates high risk
- Authentication and OAuth support remain unreviewed
- Community-maintained rather than official vendor support
- Read-only mode and security controls not yet audited
