Best uncategorized MCP servers (2026)

100 uncategorized 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.

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).

FAQ
