Excalidraw MCP with Claude: Turn Plain Language Into Hand-Drawn Diagrams
The short answer
Claude works with Excalidraw through the Model Context Protocol (MCP), an open standard that lets Claude use other software securely. Through Excalidraw's MCP server, Claude can create hand-drawn style diagrams, edit existing scenes, control the viewport camera and open fullscreen editing, all from plain-English instructions.
What is Excalidraw MCP?
Excalidraw is a tool for creating simple, hand-drawn style diagrams, flowcharts, wireframes and visual sketches. Teams use it to plan products, map processes, explain systems and capture ideas quickly in a whiteboard-like canvas. It suits product managers, designers, engineers, operations leads and educators who want clear visuals without heavy design software. Excalidraw MCP is the server that lets AI tools work with these drawings directly.
How Claude connects to Excalidraw MCP through MCP
The Model Context Protocol is an open standard that acts as a universal adapter between Claude and other software. It lets Claude read information from a tool and take actions in it, with permissions the organisation controls. For Excalidraw, this means Claude can work on your diagrams the way a colleague would, but only in the ways you have allowed.
Once connected, Claude can typically generate a new diagram from a written description, add or rearrange shapes and connectors in an existing scene, and move the viewport camera to focus on a particular area. It can also open the scene in fullscreen editing so a team can review and refine the work together. This server requires no sign-in, so access is governed by how the connection is hosted and configured.
Permissions and approvals keep people in charge. Your team decides which scenes and actions Claude may access, and sensitive or client-facing diagrams can be routed through a review step before anything is shared. Activity can be logged so you can see what was created or changed and when.
What you can automate
Process mapping for operations teams
An operations lead describes a customer onboarding process in a few sentences. Claude produces a hand-drawn flowchart showing each handoff, decision point and system involved. The team reviews it in fullscreen editing, adjusts a few steps and saves the final version for training new staff.
Product and feature planning
Product managers can ask Claude to sketch user journeys or feature maps during planning meetings. The diagrams update live as the group discusses options, giving everyone a shared visual reference without anyone needing to learn drawing software.
System architecture overviews
Engineering leads often need quick diagrams showing how services connect. Claude can draw a first version of the architecture from a brief description, which the engineering team then refines. This speeds up design reviews and keeps documentation current.
Workshop and training materials
Trainers and facilitators can request simple visuals for workshops, such as a stakeholder map or a cycle diagram. Claude creates the sketch, and the facilitator adjusts the camera view to highlight each part as they present.
Wireframes for early design discussions
Designers and business owners can explore rough layouts for a web page or app screen before committing time to detailed design. Claude produces a quick sketch that invites feedback, and the team can move on to polished design once the direction is agreed.
An end-to-end workflow: Onboarding process diagram from HR request to finance setup
TriggerA new hire is confirmed in the HR system, and the HR coordinator asks Claude for an updated onboarding map.
Claude reads the current onboarding steps recorded in the HR system.
Claude creates a hand-drawn Excalidraw flowchart showing each stage, owner and dependency.
The HR coordinator opens the diagram in fullscreen editing and marks any steps that have changed.
Claude updates the scene with the approved changes and adjusts the camera to show the revised section.
A copy of the final diagram is filed alongside the onboarding checklist in Microsoft 365 for the team to use.
OutcomeHiring managers and new starters get a clear, current onboarding map, and the HR team spends less time redrawing it by hand. Typical results vary with how often processes change.
How we set it up
Free automation audit
We review your current workflows and identify where Excalidraw diagrams would save time, such as process maps, planning sessions or architecture reviews.
Connect Claude to Excalidraw
We connect Claude to Excalidraw through its MCP server. This server uses no sign-in, so we set up the connection securely and restrict access to the scenes and actions you approve.
Design the end-to-end workflow
We map how diagrams flow into your other systems, such as Microsoft 365, your CRM or your ticketing tool, and agree which steps need a person to approve before anything is shared.
Test and launch
We test the workflow against real past examples, switch on monitoring and audit logs, and launch it with your team.
Train your team
We train your staff on writing clear requests, reviewing drawings in fullscreen editing and handling approvals, so the workflow stays in their hands.
Who benefits
- Operations managers
- Map processes quickly and keep them current without redrawing them by hand.
- Product managers
- Turn planning discussions into shared visuals during meetings.
- Engineering leads
- Produce first-draft architecture diagrams that speed up design reviews.
- Trainers and facilitators
- Create simple visuals for workshops and guide the view as they present.
Security and control
- Access is limited to the scenes and actions you approve, following least-privilege principles.
- Consequential or client-facing diagrams pass through a human review step before sharing.
- Activity is logged so you can see what Claude created or changed and when.
- Sensitive diagrams can be kept out of the connection entirely by agreement.
- Staff are trained to check AI-generated drawings for accuracy before relying on them.
For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can host the connection in a region that matches their internal data policies. Companies in India must consider the Digital Personal Data Protection Act, 2023, when diagrams contain personal data. Organisations in the UAE and Saudi Arabia must follow their local data protection laws. We choose the hosting region for each project so it meets your requirements.

Frequently asked questions
What does the Excalidraw MCP server do?
The Excalidraw MCP server lets AI tools such as Claude create and edit hand-drawn style diagrams in Excalidraw. It can also control the viewport camera and open fullscreen editing. It works through natural language, so people can describe what they want instead of drawing every shape themselves.
Is Excalidraw MCP secure?
The server requires no sign-in, so security depends on how the connection is set up. We restrict which scenes and actions are available, keep activity logs and add approval steps for sensitive work. This keeps your diagrams under your control.
What can Claude do with Excalidraw once connected?
Typically, Claude can generate new diagrams from a written description, add or change shapes and connectors in existing scenes, move the camera to focus on specific areas and open a scene in fullscreen editing for review. What it can do in your setup is defined during the design stage.
How long does setup take?
Many projects take a few weeks from the free audit to launch, depending on how many systems are involved and how much testing is needed. A simple diagram workflow with no other systems can be quicker. We confirm a timeline after the audit.
What plan or permissions do I need?
Because the Excalidraw MCP server uses no sign-in, there is no separate account to link for the connection itself. You will need access to the Excalidraw scenes you want Claude to work on, and your IT team should approve how the connection is hosted. We confirm the exact requirements during the audit.
