#excalidraw

The simplest, most complete, end-to-end agent-managed company brain. One workspace where humans and any MCP-compatible AI agent (Claude, Cursor, Windsurf, ChatGPT, Gemini, and more) co-author living documents (Markdown-native with a rich superset on top), 40+ visual diagrams (Mermaid, BPMN 2.0, D2, PlantUML, GraphViz, ELK, Excalidraw freehand), plans, timelines, tasks, improvements, and a self-learning Knowledge Graph that IS the company brain. Lean, fast, secure, and affordable — flexible enough for one person organising a personal mind, through to small businesses, growing businesses, and enterprise. 163 MCP tools across 16 categories let an agent drive end-to-end: sign-up → billing → org/workspace/project → members → teams → permissions → brain scope → docs → diagrams → plans, all without a human touching the UI. Auth: OAuth 2.1 with Dynamic Client Registration, or Bearer API key with prefix sta_. Public repo: https://github.com/stablebaseline/mcp · Docs: https://stablebaseline.io/docs/mcp
