text · LibreOffice MCP Server MCP: Risk & Policy

WHAT IT DOES

What text does on LibreOffice MCP Server

AI agents use text to create or update resources in LibreOffice MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LibreOffice MCP Server environment.

WHY IT NEEDS A POLICY

Why text needs a policy

The tool appears to manipulate text within LibreOffice documents based on server context and naming conventions. This is a Write operation (modifies data reversibly) rather than Read (no side effects) or Destructive (irreversible). Severity is medium because unintended text modifications could corrupt documents but are typically reversible via undo.

From the tool's definition Tool named 'text' on LibreOffice MCP Server which 'enables AI assistants to create, read, edit, and manipulate LibreOffice documents'. Sibling tools include 'insert_text_at_position' and 'create_document', indicating this tool modifies document content.

Verdict

text Rate-limited

text stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
