Convert a document to a different format Args: source_path: Path to the source document target_path: Path where converted document should be saved target_format: Target format (pdf, docx, xlsx, pptx, html, txt, etc.)
AI agents use convert_document 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.
This tool writes a new document file to disk in a specified format. While the operation is reversible (the converted file can be deleted), it modifies the filesystem by creating or overwriting files. It does not execute arbitrary code, delete data, or move money.
From the tool's definition Tool creates a new file at target_path with converted document content. The description states 'saved' at target_path, indicating file creation/modification.
Documented attack patterns abuse exactly the kind of access convert_document gives an agent:
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 convert_document:
{
"version": "1",
"default": "deny",
"tools": {
"convert_document": {
"limits": [
{
"counter": "convert_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}convert_document 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.

Convert a document to a different format Args: source_path: Path to the source document target_path: Path where converted document should be saved target_format: Target format (pdf, docx, xlsx, pptx, html, txt, etc.). It is categorised as a Write tool in the LibreOffice MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the LibreOffice MCP Server MCP server in PolicyLayer and add a rule for convert_document: 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 Server. Nothing to install.
convert_document is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the convert_document 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 convert_document. 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.
convert_document is provided by the LibreOffice MCP Server MCP server (patrup/mcp-libre). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
