Draw diagrams from your code in Cursor with ExcaliClaw

Cursor already knows your codebase. Add the ExcaliClaw MCP server and it can turn that knowledge into a diagram you can open, edit and share, without leaving the editor.

Add ExcaliClaw to Cursor

Open Cursor and go to Settings, then MCP, then Add new MCP server.
Paste this configuration:
Save, and sign in with your ExcaliClaw account when Cursor opens the browser.

{ "url": "https://excaliclaw.com/mcp" }

Sign-in is OAuth, so there is no API key to manage.

What to ask Cursor

"Diagram how a request moves through this repo, from the router to the database, and give me the link."
"Create an ER diagram of the tables defined in our migrations."
"Draw the architecture of this service with React, Redis and AWS icons."
"Add a sticky note to the architecture drawing listing what we still have to refactor."

Why it fits a coding workflow

Documentation diagrams go stale because redrawing them is tedious. When the assistant can read the code and draw in the same step, regenerating a diagram after a refactor costs one sentence. The diagram nodes can carry hand-drawn icons, and if you saved a component in your ExcaliClaw library, that exact shape is reused.

Share and keep the result

Every diagram Cursor creates is a normal drawing in your workspace: saved automatically, filed in a collection, searchable and shareable with your team by username or by a read-only link.
