AI agents use create_report to create or update resources in Libreoffice — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Libreoffice environment.
The tool name and server context strongly suggest this creates a new report document or report structure within LibreOffice, which is a reversible data creation operation (Write category). Severity is medium because report creation could affect document state and potentially overwrite existing content, but the operation is typically reversible.
From the tool's definition Tool name 'create_report' on a LibreOffice MCP server with document management and data analysis capabilities. Context shows similar sibling tools like 'create_chart', 'create_table', and 'create_pivot_table' which are Write operations.
Documented attack patterns abuse exactly the kind of access create_report gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Libreoffice, and nothing reaches the server without passing your rules. This is the rule we recommend for create_report:
{
"version": "1",
"default": "deny",
"tools": {
"create_report": {
"limits": [
{
"counter": "create_report_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_report 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.

create_report. It is categorised as a Write tool in the Libreoffice MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Libreoffice MCP server in PolicyLayer and add a rule for create_report: 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. Nothing to install.
create_report 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 create_report 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 create_report. 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.
create_report is provided by the Libreoffice MCP server (waterpistolai/libreoffice-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Libreoffice, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
