A whiteboard sketch without leaving the conversation
Explaining an architecture or a process usually means opening a whiteboard tool, dragging boxes and arrows, then pasting a screenshot. With this connector, you describe the picture to Claude. It draws it in Excalidraw's hand-drawn style inside the chat, element by element, and you can open it full screen to adjust it yourself before sharing.
A diagram from one sentence. A product manager asks for a user connecting to an API server that talks to a database. Claude checks the element format with read_me, then draws it with create_view, the shapes appearing one by one in the reply.
Hands-on tweaks. You open the drawing full screen and move a box. The embedded editor stores that state through save_checkpoint, and read_checkpoint brings it back when the drawing reloads.
A link for the team. When the sketch is ready, the editor's export sends it to excalidraw.com through export_to_excalidraw and returns a link you can paste into a ticket, a doc or a chat.
What it will not do: no source mentions an Excalidraw account, so nothing is read from or filed into a personal library, and nothing runs on its own. Claude only draws while answering you. To generate diagrams from data on a schedule, look at automation platforms on the Integrations hub.
Five words before you connect
The Claude vocabulary used on this page, in a minute.
- Connector
- The link you set up once between Claude and an outside service, so Claude can use it while it answers you.
- Tool
- One named job a connector opens to Claude or to its embedded editor. The directory sheet lists every one by name.
- Authorization
- Usually the service's sign-in screen, where you hand Claude its access. No source describes one for this connector.
- Approval
- The confirmation Claude waits for before it changes or sends something, shown in the conversation when it matters.
- MCP
- The shared standard connectors are built on: it is what lets an assistant like Claude talk to an outside service such as Excalidraw.
Connect the Claude Excalidraw connector in three steps
- 01
Find Excalidraw in Claude
Open Claude's settings, go to Customize then Connectors, and look for Excalidraw. On a Team or Enterprise workspace, an Owner or Primary Owner must turn the connector on before members can use it.
- 02
Add it
Click Connect on its row. If a sign-in window appears, it belongs to the service; no source we hold describes one for Excalidraw. If drawings stop showing later, Disconnect and connect again.
- 03
Try a first drawing
Ask Claude for a simple diagram and check that it appears in the conversation as an interactive drawing you can open full screen. That confirms the in-chat editor works on your side before you rely on it.
The 5 tools, and who calls each one
Excalidraw gives Claude 5 tools: 3 that read your account, 2 that change something in it.
Five tools, described in the code of Excalidraw's official repository. Claude calls two of them; the other three are called by the editor shown in the chat. Names stay as Claude displays them.

What reads or displays (3)
3 toolsThree tools that return a reference, show a drawing or bring back an edited state.
read_me
Returns Excalidraw's element format guide, with colour palettes, examples and tips. The code tells Claude to consult it before its first drawing in a conversation.
create_view
Renders a hand-drawn diagram from Excalidraw elements right in the conversation, each element streaming in with a drawing animation. The code marks it read-only: it displays, it does not file anything away.
read_checkpoint
Brings back the stored state of a drawing you reworked by hand, so the editor can restore your version rather than the original. The editor calls it, not Claude.
What stores or uploads (2)
2 toolsTwo tools, used by the embedded editor, that keep your edits or put the drawing on excalidraw.com.
export_to_excalidraw
Approval: see the ruleUploads the diagram to excalidraw.com and returns a shareable link. Per the code, the embedded editor calls it, not Claude itself.
save_checkpoint
Approval: see the ruleStores the state of a drawing after you edit it by hand in full screen, so the change survives a reload. The code labels it private to the editor.
What Claude asks before acting
By default, Claude stops and asks for your go-ahead before any action it takes on an account for you. The request appears in the conversation, right when it matters.
On Team and Enterprise workspaces, owners decide whether a member may let some actions through without being asked again. They can also cap what a connector may do for the whole organization, for example keep reading and close writing, and nobody overrides that from their own account. Claude works with the access of the person using it and nothing more. Here, per the code, the two storing tools are called by the embedded editor, not by Claude.
Which plans include it
None of the 819 sheets in the official directory displays availability by plan. Connector by connector, the answer is not published anywhere: it is a real gap in the catalogue.
What is published is the general rule: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile. On Team and Enterprise, an Owner or Primary Owner enables the connector for the organization before members use it. Check its sheet in the official directory for the current status. Only Excalidraw's repository documents this connector; no Claude help article covers it.
Where this connector stops
A connector is not an automation. Claude draws while it answers you; nothing redraws a diagram when your system changes.
The tool list is an observed floor, not a promise: an administrator can open actions that no public sheet shows. The partner badge is not a security audit, and Anthropic states on every sheet that it does not pick a publisher's tools or guarantee their behavior. Here, everything comes from the open-source repository published under Excalidraw's name, and no source says whether Claude asks for confirmation before export_to_excalidraw or save_checkpoint.
