# How to Do Quick Fact-Checking with Copilot

Copilot puts Wikipedia at your fingertips inside your editor for the constant small research moments that arise during development. Verify a date in your documentation, look up a technical concept before choosing an implementation approach, check the background of a technology mentioned in a code review, or extract structured reference data for your application -- all without opening a browser tab or losing your place in the codebase. The zero-context-switch access makes you more likely to verify assumptions rather than guessing.

## Setup

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

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Verify this date using wikipedia-lookup: Python was first released in 1991"
3. Copilot checks Wikipedia and confirms or corrects the claim
4. Ask Copilot to verify other technical facts in your documentation
5. Fix any inaccuracies directly in your files

## Example Prompt

```
Verify the historical facts in our company timeline page using wikipedia-lookup. Check the dates for major tech events we reference.
```

## Tips

- Ideal for verifying dates, version numbers, and historical claims in documentation
- Copilot can fix inaccuracies inline as it verifies
- Use when writing changelog entries or historical context in docs
