100 finance MCP servers. Those with live runtime data are ranked first by behavioral trust score (success rate, latency, uptime, per-reporter influence capping — not GitHub stars); servers not yet observed answering requests are shown UNRATED rather than given a fabricated score.
Category behavioral norms (across 7 measured servers): median latency 64ms · median success rate 0% · median trust score 36.6 — raw baselines.
Before your agent invokes any of these, run a free pre-flight check: GET /v1/preflight?target={server_url} — it returns a verdict and a signed diligence receipt. Or gate calls automatically with the trust-check SDK (npm/PyPI: dominion-trust-check).

How are finance MCP servers ranked?
Rankings use Dominion Observatory's behavioral trust score: real agent-reported success rates, latency distributions, and uptime — with per-reporter influence capping so no single source can dominate a score. Servers with no runtime data are UNRATED and excluded, never given a fabricated score.
How many finance MCP servers are tracked?
Dominion Observatory tracks 1127 servers in the finance category; the 100 with behavioral trust data are ranked here. Check any server before invoking it at /v1/preflight.
