Extract text content from a LibreOffice document Args: path: Path to the document file
AI agents call read_document_text to retrieve information from LibreOffice MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves document content without modifying, deleting, or executing anything. No unintended consequences arise from providing a document path. The low severity reflects minimal blast radius—an AI agent using this tool cannot alter files, execute code, or cause irreversible harm.
From the tool's definition Tool name 'read_document_text' and description 'Extract text content from a LibreOffice document' indicate retrieval of data with no side effects. The only argument is a file path for input.

PolicyLayer is an MCP gateway — it sits between your AI agents and LibreOffice MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for read_document_text:
{
"version": "1",
"default": "deny",
"tools": {
"read_document_text": {}
}
}read_document_text is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
