AI agents call document_open 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 tool opens a file and returns a handle/identifier for subsequent operations. It does not modify, create, or delete any data — it simply reads the file into memory and provides a reference. The automatic conversion for legacy formats is an internal parsing step, not a permanent file modification. Severity is low as the blast radius of misuse is minimal.

Open a document file and return a docId handle for use with other tools. Supports: .docx, .doc, .xlsx, .xls, .pptx, .ppt, .odt, .ods, .odp, .rtf, .csv, .txt, .pdf Legacy binary formats (.doc, .xls, .ppt, .odt, .ods, .odp, .rtf) are automatically converted via LibreOffice before parsing. Returns docId to use with all other document tools. 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_open: 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_open 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_open 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_open. 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_open 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.
