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.

About IP2WHOIS MCP Server

Connect your IP2WHOIS account to any AI agent and access comprehensive domain intelligence through natural conversation.

When paired with CrewAI, IP2WHOIS becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call IP2WHOIS tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

What you can do

WHOIS Lookup — Get complete registration records for any domain including dates, registrar, and contacts.
Domain Age — Calculate how old a domain is in days and years.
Expiry Monitoring — Check when domains expire and how many days remain.
Registrar & Nameservers — Extract registrar details and DNS nameserver configurations.
Availability Check — Determine if a domain is available for registration.
Reverse IP — Find all domains hosted on a specific IP address.
Bulk Lookup — Query up to 10 domains in a single operation.

The IP2WHOIS MCP Server exposes 10 tools through the Vinkius. Connect it to CrewAI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use CrewAI with the IP2WHOIS MCP Server

CrewAI Multi-Agent Orchestration Framework provides unique advantages when paired with IP2WHOIS through the Model Context Protocol.

Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the `mcps` parameter and agents auto-discover every available tool at runtime

Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

IP2WHOIS + CrewAI Use Cases

Practical scenarios where CrewAI combined with the IP2WHOIS MCP Server delivers measurable value.

Automated multi-step research: a reconnaissance agent queries IP2WHOIS for raw data, then a second analyst agent cross-references findings and flags anomalies. all without human handoff

Scheduled intelligence reports: set up a crew that periodically queries IP2WHOIS, analyzes trends over time, and generates executive briefings in markdown or PDF format

Multi-source enrichment pipelines: chain IP2WHOIS tools with other MCP servers in the same crew, letting agents correlate data across multiple providers in a single workflow

Compliance and audit automation: a compliance agent queries IP2WHOIS against predefined policy rules, generates deviation reports, and routes findings to the appropriate team

Example Prompts for IP2WHOIS in CrewAI

Ready-to-use prompts you can give your CrewAI agent to start working with IP2WHOIS immediately.

"Look up the WHOIS information for github.com."

"Check if the domain coolstartup2026.com is available."

"When does google.com expire?"

Troubleshooting IP2WHOIS MCP Server with CrewAI

Common issues when connecting IP2WHOIS to CrewAI through the Vinkius, and how to resolve them.

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.

Rate limiting or 429 errors

Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.

IP2WHOIS + CrewAI FAQ

Common questions about integrating IP2WHOIS MCP Server with CrewAI.

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
