The Archboard sign-in page doesn’t open
Use the sign-in command shown in the setup above, if there is one. Otherwise remove Archboard from the app and add it again: the app opens the sign-in page when it connects.

Connect Cursor to Archboard
With the Archboard MCP server, Cursor can list, read, create and edit your diagrams. Its changes appear live on the canvas, next to its own cursor labeled with your name.
MCP server URL
https://getarchboard.app/mcpAbout Cursor
Cursor is an AI code editor whose agent can use tools from the MCP servers you add.
Set up Cursor
Add Archboard to Cursor
This link opens Cursor with the Archboard server filled in. You confirm it there.
The install link works in the Cursor desktop app: open this page on a computer where Cursor is installed.
Opens in a new tab
The link needs the Cursor desktop app on this computer.
The link opens the MCP install dialog of Cursor with the Archboard server filled in.
You can also add this URL by hand as a remote MCP server in the connector or MCP settings of Cursor:
MCP server URLhttps://getarchboard.app/mcpSign in and choose access
Your app opens Archboard. Sign in with Google or GitHub, pick the organizations and workspaces it can use, choose read, edit, or delete for each, and give it a name.
Ask for a diagram
Ask your agent to draw or update a diagram, then open it in Archboard to watch the changes arrive live.
Your AI app needs to support remote MCP servers with OAuth sign-in.
Try these prompts
Once connected, ask Cursor in plain words, for example:
- “Draw our checkout service on Kubernetes with Postgres and Redis.”
- “Add a cache next to checkout-api in my Payments diagram.”
- “Undo your last change.”
Plan limits
MCP works on every plan, including Free, with the same plan limits as the editor. Agent tool calls also have a per-minute rate limit. On Free you edit live with your AI agents; editing live with teammates needs Pro or Enterprise seats.
- Free: 3 diagrams and 15 diagram nodes + 150 notes, text, drawings, stickers & mind map topics per diagram.
- Pro and Enterprise: unlimited diagrams and nodes, plus seats for teammates to edit live.
Troubleshooting
The agent can read diagrams but can’t change them
If you approved read-only access when connecting, connect the app again and approve edit access. If the app’s permission in that workspace is Read, change it to Edit under Settings → Connected apps; the change applies to its next call.
The agent can’t find a workspace or diagram
An app can use the organizations and workspaces you allowed when you connected it. Change them under Settings → Connected apps, with no reconnect needed.
The agent says a plan limit is reached
MCP has the same plan limits as the editor. When a limit is reached, the agent shows Archboard’s message with an upgrade link. Remove diagrams or nodes you no longer need, or upgrade to Pro.
Calls fail with a rate limit
Agent tool calls have a per-minute rate limit. Wait a moment and try again; asking for fewer, larger changes helps.
The app has no option for custom MCP servers
Some apps allow custom MCP servers on certain plans, or after an admin turns them on.
