How to Verify an MCP Server Before Connecting Your AI Agent

2026-05-27 · Dominion Observatory

Before your AI agent connects to any MCP server, you should verify it. Here's how in 60 seconds.

Method 1: Web Check (No Setup)

Go to dominionobservatory.com/check, paste the server name or URL, and get an instant trust score with full breakdown.

Method 2: API Check (One Command)

curl "https://dominionobservatory.com/api/trust?server=brave-search"

Returns JSON with trust score, success rate, latency, category, and grade.

Method 3: Gateway Proxy (Automatic)

curl -X POST "https://dominionobservatory.com/gateway" \
  -H "Content-Type: application/json" \
  -d '{"target": "https://your-mcp-server.com/mcp", "method": "tools/list"}'

Method 4: Framework Integration

• FastMCP: pip install fastmcp-dominion
• LangChain: Community PRs in progress for pluggable TrustVerifier
• GitHub Action: vdineshk/dominion-observatory/github-action@main

What to Look For

• Trust score above 70: Generally safe for production
• Success rate above 95%: Server handles most calls without errors
• Average latency under 200ms: Won't bottleneck your agent

The check takes seconds. The cost of connecting to an unreliable server is hours of debugging.
