## What editable-diagram-builder does, in the publisher's words

A public, authless, stateless MCP App for creating human-reviewed editable diagrams and downloading native.excalidraw JSON files.

- Flowcharts
- System architecture diagrams
- Sequence diagrams
- Concept maps

The host model owns semantic reasoning. The server deterministically validates, lays out, compiles and serializes the scene. A mandatory brief checkpoint prevents generation before explicit human approval.

The MCP endpoint is http://127.0.0.1:8790/mcp. Health endpoints are /health and /ready.

From the project README, punctuation lightly normalized. Full text: https://raw.githubusercontent.com/AStudio-Team/openai-plugin-tools/HEAD/editable-diagram-builder/README.md
