TrustRails MCP Server
Search UK electronics products - compare prices, find deals, and discover products across multiple retailers.
Built for the Model Context Protocol (MCP) - works with Claude Desktop, Claude Code, and other MCP-compatible AI assistants.
Quick Start
No installation needed — just add TrustRails to your Claude config.
Configuration
For Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
{
"mcpServers": {
"trustrails": {
"command": "npx",
"args": ["-y", "@trustrails/mcp-server"],
"env": {
"TRUSTRAILS_API_KEY": "mcp-public-2026"
}
}
}
}
For Claude Code (~/.config/claude/config.json):
{
"mcpServers": {
"trustrails": {
"command": "npx",
"args": ["-y", "@trustrails/mcp-server"],
"env": {
"TRUSTRAILS_API_KEY": "mcp-public-2026"
}
}
}
}
That's it! Restart Claude and start searching.
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
