GitNexus turns a codebase into a queryable knowledge graph and exposes it through MCP, making impact analysis and symbol-level navigation far more useful for large repositories. Strong idea, but the PolyForm Noncommercial license sets a clear boundary for commercial adoption.
Edit Banana aims at a very specific but valuable problem: converting diagrams from images or PDFs into editable DrawIO, SVG, or PowerPoint output. The technical ambition is impressive, but the real story includes GPU requirements, model downloads, and a non-trivial setup.
Claudian is worth considering if Obsidian is already one of your real work surfaces, not just a note archive. It brings Claude Code-style file operations into the vault, but the extra power only makes sense if you actually want that level of access.
Chrome DevTools MCP is only worth considering if you need deep Chrome-specific debugging or performance traces. If your browser workflow is already covered by Playwright MCP, the overlap is high and the extra layer is usually unnecessary.
The official draw.io MCP server lets your LLM generate, preview, and export editable diagrams mid-conversation. Free, open-source, with 10,000+ shapes including AWS, Azure, GCP, and UML libraries. Best for developers and researchers who need architecture or workflow diagrams without leaving their AI chat. Hosted endpoint means zero setup; self-host if you handle sensitive data.
