# How to Evaluate Listing Quality with Claude

Assess seller reliability and listing accuracy by pulling detailed listing data and cross-referencing against similar items. Claude excels at reasoning through red flags: inconsistent pricing, vague descriptions, mismatched photos, and seller patterns that suggest low reliability.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter in Claude: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Share the listing you want to evaluate, including the product name, source, and any concerns you already have.
3. Use `marketplace-search` with `listing_details` to pull the full listing information, then `search_listings` to find comparable items across sources.
4. Ask Claude to compare the listing against comparable results and flag any inconsistencies in price, condition, description detail, or seller profile.
5. Get a verdict on whether the listing looks trustworthy, overpriced, or suspicious, with specific reasons.

## Example Prompt

```
Use marketplace-search to evaluate a used MacBook Pro listing I found. Pull the full listing details, then search for comparable MacBook Pro listings across other sources. Tell me if the price is fair, whether the condition claims look credible, and flag any red flags in the listing or seller profile.
```

## Tips

- Always compare against at least five similar listings to establish a realistic price range.
- Ask Claude to check whether the listing description matches the photos and stated condition.
- Flag listings with generic or stock photos as higher risk regardless of price.
