This tool creates new content in a Google Doc by inserting a footnote. This is a Write operation because it modifies a document by adding structured content, and the change is reversible. The severity is low because footnotes are minor content additions with minimal blast radius—they do not delete data, execute code, or have financial implications.

Documented attack patterns abuse exactly the kind of access createFootnote gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Drive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for createFootnote:
{
"version": "1",
"default": "deny",
"tools": {
"createFootnote": {
"limits": [
{
"counter": "createfootnote_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}createFootnote 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.

Yes. Add a rate_limit block to the createFootnote 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 createFootnote. 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.
