Update the title or body text of an existing slide.
AI agents use presentation_update_slide to create or update resources in LibreOffice MCP Tools — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LibreOffice MCP Tools environment.
The tool creates or modifies data (slide content) in a reversible manner without deleting or destroying information. It falls under Write rather than Execute because it directly manipulates document content via a structured API rather than executing arbitrary code.
