The Lucid MCP Server just got a massive upgrade with the addition of Document Editing and UML Sequence Generation. Now, your AI assistant can act as a true collaborative editor in your source of truth.
Edit Documents
Editing your documents through the MCP upgrades the MCP’s capabilities to go from creating a snapshot to maintaining a living documentation. With this new feature, your LLM can now add, update, or remove shapes within any Lucid document.

Use Case: Real-Time Sync
Stop pausing your meetings to move update documents.
- The Scenario: You reserve updates from your team that three workstreams were just completed.
- The Prompt: "In my Q3 Roadmap in Lucid, update the color 'for 'Mobile Auth' and 'API Sync' to green, and add a new sticky note that says 'Deployment Complete'."
- The Result: Your board is updated instantly, allowing you to easily maintain your source of truth.
UML Sequence Diagramming
Technical documentation just got a speed boost. By utilizing PlantUML-style logic, you can describe service interactions in plain language and have the MCP generate a styled, customizable UML sequence diagram.

Use Case: Rapid Backend Architecture Design
- The Scenario: You’re in Claude Code or ChatGPT, outlining a new multi-factor authentication flow.
- The Action: Describe the participants (User, Gateway, Auth Service) and the logic.
- The Prompt: "Generate a UML sequence diagram for this MFA flow in Lucid."
- The Result: You skip the manual alignment and styling entirely, moving from abstract logic to a shareable visual source of truth in seconds.
