Check availability of up to 50 domain names in one call.
AI agents call check_domains_bulk to retrieve information from InstaDomain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves domain availability status without modifying, creating, deleting, or executing any operations. It is a simple bulk read operation similar to a search or list function. No financial transactions, code execution, or data mutation occurs. Low severity because misuse would only expose public domain availability information.
From the tool's definition Tool name 'check_domains_bulk' and description 'Check availability of up to 50 domain names in one call' indicate a query operation with no side effects. The verb 'check' and 'availability' query represent read-only operations.

Check availability of up to 50 domain names in one call. It is categorised as a Read tool in the InstaDomain MCP Server, which means it retrieves data without modifying state.
Register the InstaDomain MCP server in PolicyLayer and add a rule for check_domains_bulk: 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 InstaDomain. Nothing to install.
check_domains_bulk 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 check_domains_bulk 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 check_domains_bulk. 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.
check_domains_bulk is provided by the InstaDomain MCP server (nach-dakwale/instadomain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
