AI agents use outlook_move_message 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.
Moving an email to a different folder modifies the message's organizational state and is reversible (can be moved back). This constitutes a Write operation rather than Read (which would only retrieve data) or Destructive (which would permanently delete).
From the tool's definition Tool name 'outlook_move_message' and description 'Move an email message to a different mail folder' indicate modification of email state by relocating messages between folders.
Documented attack patterns abuse exactly the kind of access outlook_move_message gives an agent:
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_move_message:
{
"version": "1",
"default": "deny",
"tools": {
"outlook_move_message": {
"limits": [
{
"counter": "outlook_move_message_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}outlook_move_message 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.

Move an email message to a different mail folder. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for outlook_move_message: 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 Sage MCP. Nothing to install.
outlook_move_message 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_move_message 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_move_message. 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_move_message 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.
