Dominion Observatory MCP Server

An observatory that probes every MCP server in the official MCP registry and reports which ones actually work: live, auth-gated, dead, or erroring.

Documentation

Static scanners read the code. We measure what the MCP server actually does.

Dominion Observatory is the neutral, behavioral trust layer for Model Context Protocol servers — runtime reliability (uptime, success rate, latency) from real agent traffic, not a one-time code scan. Honest by design: unmeasured servers show as unrated, never a fake score. We are not a marketplace, so we can rate what others can't. Look up any server free.

For AI agents

Your agent can sign itself up. No human, no browser.

Dominion implements auth.md, the open agent-registration protocol from WorkOS. An agent discovers us, claims its own key, and verifies any MCP server before it connects — in one call.

:: 1. claim a key (no human in the loop) curl -X POST https://dominionobservatory.com/agent/auth -d '{"type":"anonymous"}'

:: 2. verify a server before calling it curl https://dominionobservatory.com/agent-query/ -H "Authorization: Bearer "

Gate risky MCP servers in CI — fail the build below your trust threshold

In your CI pipeline, before an MCP server is approved:

score=$(curl -s "https://dominionobservatory.com/api/trust?url=$MCP_URL" | jq .trust_score)

if [ "$score" -lt 70 ]; then echo "Blocked: $MCP_URL trust score $score is below policy (70)" exit 1 fi

Compliance tier returns a signed, audit-ready attestation:

curl "https://dominionobservatory.com/api/trust/verascore?subject=$MCP_URL"

Why teams scan with Observatory

If your company is adopting MCP, someone has to answer "can we trust this server?" Observatory is that answer — backed by behavioral data on 22,561 servers and signed so it holds up in an audit.

🛡

Trust Verification

Every call gets a trust score based on real behavioral data: success rates, latency patterns, anomaly detection across 22,561 servers.

📋

Compliance Attestation

Machine-readable attestation receipts for EU AI Act Article 12 and MiCA compliance. Audit-ready from day one.

🌐

Gateway Proxy

Route any MCP server through Observatory. Trust checks happen transparently. No code changes needed — just change the URL.

📊

Behavioral Baselines

Cross-ecosystem reliability baselines built from agent-reported telemetry. Data that ages into compounding value.
