AI agents use create-folder to create or update resources in Enhanced Gmail MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Gmail MCP Server environment.
This tool creates new organizational structures within Gmail (folders/labels), which is a reversible modification of account state. It does not delete data (not Destructive), does not execute arbitrary code (not Execute), does not involve financial transactions (not Financial), and does not merely retrieve information (not Read).
From the tool's definition Tool name is 'create-folder' and description states it 'Creates a new folder'. In the context of Gmail, folders are organizational structures (labels in Gmail's terminology) that persist and organize emails.
Documented attack patterns abuse exactly the kind of access create-folder gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Enhanced Gmail MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create-folder:
{
"version": "1",
"default": "deny",
"tools": {
"create-folder": {
"limits": [
{
"counter": "create-folder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-folder 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.
Free to start. No card required.
Creates a new folder. It is categorised as a Write tool in the Enhanced Gmail MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Enhanced Gmail MCP Server MCP server in PolicyLayer and add a rule for create-folder: 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 Enhanced Gmail MCP Server. Nothing to install.
create-folder 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-folder 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-folder. 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-folder is provided by the Enhanced Gmail MCP Server MCP server (theposch/gmail-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Enhanced Gmail MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
