List all verified domains in your account.
AI agents call list_domains to retrieve information from Unosend MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing domain information from the user's account and returns a list. It performs no creation, modification, deletion, or execution of external operations. The data retrieval has minimal blast radius—an AI agent calling this tool would only expose domain configuration information already owned by the account holder.
From the tool's definition Tool name 'list_domains' and description 'List all verified domains in your account' indicate a pure read operation that retrieves and lists data without modification or side effects.
Attacks that exploit this kind of access
List all verified domains in your account. It is categorised as a Read tool in the Unosend MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unosend MCP Server MCP server in PolicyLayer and add a rule for list_domains: 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 Unosend MCP Server. Nothing to install.
list_domains 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 list_domains 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 list_domains. 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.
list_domains is provided by the Unosend MCP Server MCP server (unosend/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
