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.

@Kelsey Gaag Is there an API to edit document content as part of this? The existing “PATCH Update Document” endpoint supports document properties, but not content.
