Architecture Diagrams Built and Maintained by AI

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

It installs in one command — npx -y flowzap-mcp — with no authentication required. It works with Claude Desktop, Cursor, Windsurf, Zed, Warp, Cline, Roo Code, Continue.dev, OpenAI Codex, and more. The core tools let AI agents validate FlowZap Code syntax, fetch syntax docs, and create shareable but temporary playground URLs (one-hour TTL). Diagrams are exported as structured JSON graphs (lanes, nodes, edges) so AI agents can reason over them. It is listed on the official MCP registry (registry.modelcontextprotocol.io), npm, GitHub, among others. Use it with its SKILL . md file for cleaner results: npx skills add flowzap-xyz/flowzap-mcp --skill flowzap-diagrams Security: No Authentication Required - Public endpoints only; No User Data Stored. Playground sessions are ephemeral (60-minute TTL, non-guessable cryptographic tokens); No Tracking. No cookies or persistent identifiers Logs to stderr only - Security events never exposed to MCP clients.
