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.
| 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 |

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…
