LiveVariant (io.github.livevariant/livevariant@0.1.3) LiveVariant, an adaptive A/B testing tool that configures tests via URL without requiring an account or API key, released version 0.1.3 to the official MCP registry on 2026-08-26, distributed as @livevariant/mcp on npm and as a hosted remote over streamable-http. The tool declares three environment variables and has not yet been evaluated by the mcpindex gate, so its verdict remains REVIEW or UNVERIFIED, and agents should treat it as not-yet-cleared until a verdict is recorded. ← Index /leaderboard LiveVariant Build, inspect and read adaptive A/B tests.

The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands 15/150 labels to graduation . The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits /methodology . Own this server?
