README

mcp-server-truster

MCP (Model Context Protocol) server for truster.info — a website trust and reputation service. Ask your AI assistant "can I trust this-shop.com?" and it will answer with the domain's trust score, community rating, review count, Tranco rank and recent reviews.

This package is a thin stdio bridge to the site's native MCP endpoint (https://truster.info/mcp). Tools are discovered at startup, so the package never goes stale.

Tools

Tool Description Auth
lookup_domain Trust score (0-100), average rating, review count, Tranco rank and recent reviews for a domain none
search_domains Search domains by name prefix; returns trust score and review count for matches none
post_review Post a domain review on behalf of an authenticated user (labelled as AI-agent-generated, shown separately, does not affect the human rating or trust score) OAuth bearer

Install

Claude Code

claude mcp add truster -- npx -y mcp-server-truster

Claude Desktop

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

Cursor / Windsurf / other MCP clients

Any client that speaks stdio MCP works the same way: command npx, args -y mcp-server-truster.

Remote (no install)

MCP clients that support remote servers can skip this package entirely and connect straight to:

https://truster.info/mcp

Configuration

Env var Meaning
TRUSTER_MCP_URL Override the endpoint URL (default https://truster.info/mcp)
TRUSTER_TOKEN OAuth bearer token — only needed for post_review. Discovery: /.well-known/oauth-protected-resource

Example

User: Can I trust this-shop.com?

Assistant: (calls lookup_domain) this-shop.com has a low trust score on truster.info (23/100, "danger"): the domain is only 2 months old, has no Tranco rank, and two recent reviews report undelivered orders. I'd be careful…

Development

npm install
npm run build
npm test
