Merge multiple text documents into a single document Args: document_paths: List of paths to documents to merge output_path: Path where merged document should be saved separator: Text to insert between merged documents
AI agents use merge_text_documents 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 creates or modifies a file by merging source documents and writing the result to output_path. This is a reversible Write operation—the merged document can be deleted or edited. It does not permanently destroy data, execute arbitrary code, or involve financial transactions. While it modifies the filesystem, the operation is non-destructive and non-irreversible, placing it in the Write category.
From the tool's definition Tool description states 'Merge multiple text documents into a single document' with args for document_paths, output_path, and separator. The output_path parameter indicates a new file is created or an existing file is modified and saved.
Documented attack patterns abuse exactly the kind of access merge_text_documents 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 merge_text_documents:
{
"version": "1",
"default": "deny",
"tools": {
"merge_text_documents": {
"limits": [
{
"counter": "merge_text_documents_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}merge_text_documents 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.

Merge multiple text documents into a single document Args: document_paths: List of paths to documents to merge output_path: Path where merged document should be saved separator: Text to insert between merged documents. 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 merge_text_documents: 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.
merge_text_documents 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 merge_text_documents 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 merge_text_documents. 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.
merge_text_documents 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.
