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 (PyPI: dominion-trust-check; hosted JavaScript module).

FAQ

What is the best uncategorized MCP server in 2026?
Based on independently measured runtime behavior, https://sdk.sgdata.workers.dev/v1/observatory.py currently ranks #1 in the uncategorized category with a trust score of 85/100 across 1 tracked interactions.
How are uncategorized 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 uncategorized MCP servers are tracked?
Dominion Observatory tracks 1449 servers in the uncategorized category; the 100 with behavioral trust data are ranked here. Check any server before invoking it at /v1/preflight.
