Attacks that exploit this kind of access
Get a sending domain by ID and its verification status. Optionally include DNS setup instructions via include_setup_instructions. It is categorised as a Read tool in the Mcp Mailtrap MCP Server, which means it retrieves data without modifying state.
Register the Mcp Mailtrap MCP server in PolicyLayer and add a rule for get-sending-domain: 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 Mcp Mailtrap. Nothing to install.
get-sending-domain is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-sending-domain 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 get-sending-domain. 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.
get-sending-domain is provided by the Mcp Mailtrap MCP server (mcp-mailtrap). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
