AI agents call document_get_outline to retrieve information from LibreOffice MCP Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns metadata about document structure without any side effects. The tool cannot modify, delete, or execute actions on the document—it only extracts organizational information. The low blast radius reflects that misuse would at worst leak non-sensitive structural information, not compromise data integrity or trigger external operations.
From the tool's definition Tool retrieves document structure (headings, sheet names, slide titles) with no modification capability; description explicitly states it gets 'structural outline' and recommends calling 'before document_read_text' suggesting pure retrieval.
Attacks that exploit this kind of access
Get the structural outline of a document: - Writer documents: headings hierarchy (H1, H2, H3...) - Calc spreadsheets: list of sheet names with row/column counts - Impress presentations: slide titles with index numbers Token-efficient: always call this before document_read_text to understand structure. It is categorised as a Read tool in the LibreOffice MCP Tools MCP Server, which means it retrieves data without modifying state.
Register the LibreOffice MCP Tools MCP server in PolicyLayer and add a rule for document_get_outline: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches LibreOffice MCP Tools. Nothing to install.
document_get_outline is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the document_get_outline rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for document_get_outline. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
document_get_outline is provided by the LibreOffice MCP Tools MCP server (passerbyflutter/libreoffice-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
