# How to Check Domain Age with Copilot

Copilot integrates domain registration checks directly into your development environment, letting you verify ownership details and expiration dates without leaving your IDE. Cross-reference domains from your infrastructure configuration files, build automated expiration monitoring into your ops workflow, and verify registrar details as part of your vendor evaluation process. This tight integration catches domain-related risks during development rather than in production.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Check the age of this domain using whois-rdap"
3. Copilot returns the creation date and domain age
4. Ask: "Is this domain old enough to be trusted for our integration?"
5. Factor the age into your technical decisions

## Example Prompt

```
Check the registration age of all domains we depend on in our infrastructure. Flag any registered less than a year ago.
```

## Tips

- New dependencies on very young domains can be a security risk
- Copilot can batch-check domain ages from your dependency configuration
- Include domain age checks in your vendor evaluation process
