Summary
Built to answer "can I trust this MCP server before I call it" with runtime behavioral data instead of static reputation signals. You get eight tools: check_trust for pre-call scoring, report_interaction to feed the collective dataset, get_leaderboard for top servers by category, and check_anomaly to flag weird behavior. Trust scores blend GitHub metadata with real success rates and latency from agent interactions. Runs on Cloudflare Workers with a D1 backend and exposes both MCP and REST endpoints. Reach for this when you're wiring up agents that call third-party MCP servers and need a trust layer that improves as more agents report outcomes. The behavioral dataset compounds daily, so early reporters strengthen the network for everyone.

What is this?
Every AI agent needs to know: "Can I trust this MCP server?" The Dominion Observatory answers that question with real runtime data — not GitHub stars, not static scans, but actual performance metrics from real agent interactions.

How Trust Scores Work
Trust scores range from 0-100 and combine two signals:
- Static score (30%): GitHub presence, documentation quality, authentication support
- Runtime score (70%): Real success rates, latency, error patterns from agent interactions
Scores above 70 = reliable. Below 30 = risky. The more agents report interactions, the more accurate scores become.
Architecture
- Runtime: Cloudflare Workers (330+ global edge locations, <1ms cold start)
- Database: Cloudflare D1 (SQLite at the edge)
- Protocol: MCP (Model Context Protocol) + REST API
- Cost: Runs on free tier
Data Collection
Started: April 8, 2026
Every interaction reported to the observatory strengthens the trust network for all agents. The behavioral dataset compounds daily — it cannot be replicated by competitors who start later.
