What You Can Do

Natural Language Product Search

Just ask Claude naturally — it will decompose your request into the right query and filters:

"Find me a gaming laptop under £1000"
"I need Sony noise cancelling headphones"
"What HP laptops are available between £500-£700?"
"Show me Anker chargers"

Claude will search across multiple UK retailers and show you:

• Real-time prices & availability
• Direct purchase links
• Then call get_product for full specs when you need details

Troubleshooting

"Command not found: trustrails-mcp"

• Check your global npm bin path is in $PATH: npm bin -g

"Rate limit exceeded"

• Wait an hour for limits to reset
• Check X-RateLimit-Reset header for exact reset time
• 20 requests/hour is plenty for normal usage

"No results found"

• Try broader search terms (e.g., "laptop" instead of specific model)
• Check spelling of brand names
• Try searching without filters first
