Create a new mail folder. Can create top-level folders or child folders within an existing folder.
AI agents use outlook_create_folder to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
The tool creates (writes) new email folders, which is a reversible modification of email account state. It does not read-only operations (Read), execute arbitrary code (Execute), permanently delete data (Destructive), or move money (Financial). While folder creation could clutter an account, folders can be deleted to undo the action, making it Write rather than Destructive.
From the tool's definition Tool creates a new mail folder with the description "Create a new mail folder. Can create top-level folders or child folders within an existing folder." This is a reversible creation operation that modifies the folder structure.

PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for outlook_create_folder:
{
"version": "1",
"default": "deny",
"tools": {
"outlook_create_folder": {
"limits": [
{
"counter": "outlook_create_folder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}outlook_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.

outlook_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 outlook_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 outlook_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.
outlook_create_folder is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
