AI agents use configure_domain_email to create or modify resources in MCPDomain. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call configure_domain_email repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach MCPDomain.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access configure_domain_email gives an agent. Each links to the full case and the policy that stops it:

Set up email forwarding for a registered domain. Forward any@domain to Gmail/Outlook. No MX records needed. WHEN TO USE: user just registered a domain, or asks about professional email.. It is categorised as a Write tool in the MCPDomain MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCPDomain MCP server in PolicyLayer and add a rule for configure_domain_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 MCPDomain. Nothing to install.
configure_domain_email 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 configure_domain_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 configure_domain_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.
configure_domain_email is provided by the MCPDomain MCP server (mcpdomain). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
