Best for
  • Teams that want AI to generate or maintain Draw.io diagrams
  • Users of Claude Desktop, Claude Code, Zed, Codex, or OpenCode
  • Diagram workflows requiring multi-document, multi-page, and vendor-stencil support
  • Biomedical researchers
  • Clinicians
  • AI agents that need efficient access to biomedical literature and data analysis
Not for
  • Text-only workflows with no diagram-editing requirement
  • Users requiring a stable end-to-end Draw.io Desktop integration
  • Users unwilling to install Node.js or a browser extension
  • Users needing to write to upstream databases (read-only)
  • Users requiring direct access to closed datasets (e.g., COSMIC is not directly integrated)
  • Users expecting all advanced features without API keys
Required permissions
  • Access to connected Draw.io document instances and diagram contents
  • Permission to create, modify, and delete elements in target diagrams
  • In browser-extension mode, a connection to the Draw.io browser page and extension
  • Requires internet access to query public biomedical APIs
  • Optional API keys (NCBI, Semantic Scholar, OpenFDA, etc.) to improve rate limits or unlock features
  • Local read/write access for skills, cache, and local study data (e.g., `~/.local/share/biomcp`)
Risks and side effects
  • AI actions can modify or delete diagram elements, so mistakes may damage diagram content
  • Browser-extension mode depends on connectivity between the extension and the Draw.io page
  • Self-signed TLS certificates may require browser trust and connection configuration
  • Draw.io Desktop integration is experimental and limited by an upstream CSP issue
  • Upstream API rate limits may affect performance
  • Some data sources (e.g., KEGG) have licensing terms that restrict non-academic use
  • Features requiring API keys (e.g., OncoKB) may be incomplete without them
  • Local binary installations need regular updates for compatibility
