Feature Request: Add Update/Modify Capabilities to Lucid MCP Server

I'm currently using the Lucid MCP (Model Context Protocol) server to integrate Lucidchart with AI tools and I'm finding it incredibly useful for creating diagrams programmatically.

However, I've encountered a limitation that would significantly improve the workflow: the current MCP server only supports creating new documents but doesn't provide functionality to update or modify existing documents.

Specific use case: I have a multi-page Lucidchart document and want to add additional pages to it programmatically through the MCP server. Currently, I have to either:

1. Manually open the document and add pages, or
2. Recreate the entire document from scratch with all pages included

Feature request: Could you add MCP tools that support:

• Adding pages to existing documents
• Updating/modifying existing pages
• Deleting pages from documents
• General document update capabilities (similar to how lucid_create_diagram_from_specification works, but for existing documents)

This would enable true iterative diagram development through AI tools and make the MCP integration much more powerful for ongoing documentation workflows.

Example tool signature:

lucid_update_diagram

- documentId: string (the existing document to modify)

- operation: "add_page" | "update_page" | "delete_page"

- pageData: standard_import_json (for the page content)

Thank you for considering this enhancement. The Lucid MCP server is already a great tool, and this addition would make it even more valuable for teams using AI-assisted diagramming workflows.
