# How to View Historical Websites 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: "Check if docs.github.com has Wayback Machine snapshots from 2015 using web-archive"
3. Copilot reports available snapshots
4. Ask: "Find the earliest capture of this documentation page"
5. Use the archive data for research or reference

## Example Prompt

```
Check the Wayback Machine for snapshots of our competitor's API documentation page from last year.
```

## Tips

- Use for researching historical API documentation or changelog entries
- Copilot can compare current and historical versions of technical pages
- Ideal for checking when a specific feature was first documented
