AI agents use insert_data 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.
Insert operations are reversible (data can be edited or deleted afterward) and do not execute arbitrary code or permanently destroy data. Confidence is reduced from 0.85 to 0.75 due to empty description—the tool could theoretically accept SQL or scripts, but the name and server context suggest straightforward data insertion into document structures.
From the tool's definition Tool name 'insert_data' indicates data creation/modification in LibreOffice documents; description is empty but context shows this MCP server manages documents (Writer, Calc, Impress, Draw) with 'data analysis and database operations' capabilities.
Documented attack patterns abuse exactly the kind of access insert_data 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 insert_data:
{
"version": "1",
"default": "deny",
"tools": {
"insert_data": {
"limits": [
{
"counter": "insert_data_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}insert_data 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.

insert_data. 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 insert_data: 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.
insert_data 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 insert_data 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 insert_data. 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.
insert_data 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.
