Details
From the project READMEmcp-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

{
"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

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
