What send_email does on Nitrostack
AI agents call send_email to permanently remove resources in Nitrostack, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why send_email is rated Critical
An AI agent that decides to call send_email doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Nitrostack is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs send_email safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nitrostack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_email, this is the rule to start with:
send_email is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Nitrostack, apply this rule, and every send_email call is checked against it from then on.
Questions about send_email
Send an email. Cannot be undone — only counteracted by a retraction email within a short window. It is categorised as a Destructive tool in the Nitrostack MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Nitrostack MCP server in PolicyLayer and add a rule for send_email: 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 Nitrostack. Nothing to install.
send_email is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the send_email 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 send_email. 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.
send_email is provided by the Nitrostack MCP server (nitrocloudofficial/nitrostack). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
