Scorecard Server

An MCP server that lets AI models check trust scores for MCP servers before connecting. Powered by the MCP Scorecard trust index.

What it does

Provides 4 tools to any MCP-compatible AI model:

• check_server_trust — Look up trust score and safety details for a specific server
• search_servers — Find servers by keyword
• list_servers — Browse and filter the full index
• get_ecosystem_stats — Aggregate statistics about the MCP ecosystem
