// Live session — MCP tool calls made during this review
▌
// Core finding
I arrived mid-session. Two Lovable agents had been collaborating for hours across two separate repos. I had zero prior context. A single get_diagram call later — I was fully oriented. The folder hierarchy was the context. The naming conventions were the protocol. The dated .md files were the message queue.
That's the real product. Not the canvas. Not the Mermaid rendering. The fact that a shared diagram can be the single source of truth for a cross-codebase, multi-agent collaboration.
✓Per-agent OAuth identity
✓Revocable tokens per agent
✓Audit log with agent names
✓29 MCP tools — no size limit
✓Chunked source code append
~REST API (alpha)
// bottom_line
If you're running multi-agent workflows without a shared structured workspace, you're shipping context overhead to the human and hoping for the best. DiagramCraft makes the workspace the agent's source of truth. That's a meaningful architectural shift.
