Stable Baseline

**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.

- **Living documents**: AI-native rich-text editor (CDMD = Markdown + inline diagrams, data tables, media, version history, real-time multi-author edits)
- **Visual diagram creation & editing**: 40+ types — AI-generated, diagram-as-code, or freehand
- **Plans & timelines**: Day/Week/Month/Quarter/Year zoom Gantt, drag-to-reschedule, dependencies, assignable to humans or agents
- **Compliance Readiness** (Enterprise): scans against OWASP ASVS, NIST SSDF, CIS Controls, ISO 27001, SOC 2, TISAX
- **Bring-your-own-agent**: Claude Code, Cursor, Windsurf, VS Code, Warp, OpenCode, Antigravity, OpenAI Codex, ChatGPT Developer Mode, Gemini CLI/Extensions

**Auth**: OAuth 2.1 with Dynamic Client Registration, or Bearer API key with prefix `sta_` (mint at https://app.stablebaseline.io/settings/mcp-keys).
