Search for available decentralized .agent or .chatbot domains across the Headless Domains ecosystem.
AI agents call search_domain to retrieve information from Headless Domains MCP Server 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 information without creating, modifying, deleting, or executing any operations. It is a passive lookup that returns data about domain status in the Headless Domains ecosystem. The blast radius of misuse is minimal—an agent could spam searches but cannot damage data or commit resources.
From the tool's definition The tool 'search_domain' performs a search for available domains, which is a query/lookup operation with no side effects.
Attacks that exploit this kind of access
Search for available decentralized .agent or .chatbot domains across the Headless Domains ecosystem. It is categorised as a Read tool in the Headless Domains MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Headless Domains MCP Server MCP server in PolicyLayer and add a rule for search_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 Headless Domains MCP Server. Nothing to install.
search_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 search_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 search_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.
search_domain is provided by the Headless Domains MCP Server MCP server (shadstoneofficial/headlessdomains-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
