Frequently asked questions
Can I check if a domain is available for registration?
Yes! Use check_domain_availability with the domain name. It analyzes the WHOIS record to determine if the domain appears unregistered.
How many domains can I look up at once?
Use bulk_whois_lookup with a comma-separated list of up to 10 domains to get key registration details for each one in a single request.
Can I find which domains are hosted on a specific server?
Yes! Use lookup_hosted_domains with an IPv4 or IPv6 address to perform a reverse IP lookup and discover all domains on that server.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query IP2WHOIS tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
