Get your current custom domain configuration and DNS verification status. Returns the domain, whether DNS is active or pending, and setup instructions.
AI agents call get_custom_domain to retrieve information from QR for Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays existing configuration data (domain, DNS status, setup instructions). It performs no write, delete, execute, or financial operations. The blast radius of misuse is minimal — an attacker gains visibility into domain configuration but cannot modify it, delete it, or trigger external actions.
From the tool's definition Tool description explicitly states 'Get your current custom domain configuration and DNS verification status' — uses 'Get' and 'Returns', indicating data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Get your current custom domain configuration and DNS verification status. Returns the domain, whether DNS is active or pending, and setup instructions. It is categorised as a Read tool in the QR for Agent MCP Server, which means it retrieves data without modifying state.
Register the QR for Agent MCP server in PolicyLayer and add a rule for get_custom_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 QR for Agent. Nothing to install.
get_custom_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_custom_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_custom_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_custom_domain is provided by the QR for Agent MCP server (qr-for-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
