# How to Research Domain History with Copilot

Copilot brings Wayback Machine access into your IDE for the moments when development requires historical context from the web. Check how a third-party API documentation looked six months ago, verify when a dependency changelog entry was added, recover deleted technical references, or investigate when a competitor shipped a specific feature -- all without leaving your editor or breaking your development flow. This integration is especially valuable when debugging integration issues that may trace back to upstream documentation changes.

## Setup

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

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Get the site history for acquired-domain.com using web-archive"
3. Copilot shows the domain's archive coverage
4. Ask: "Check what this domain was used for before we acquired it"
5. Use the history to inform your migration strategy

## Example Prompt

```
Research the history of the domain we just acquired. I want to know what was there before to plan our redirect strategy.
```

## Tips

- Use for planning 301 redirects when acquiring domains with existing traffic
- Copilot can help identify old URLs that need redirecting
- Check for any backlink-worthy content that should be preserved or redirected
