trust_compare

Active

declared in 1.9.0

Compare TWO public MCP servers HEAD-TO-HEAD on SaSame's proprietary observation history — current grade/passes, trend, stability, and observation depth — and return a NEUTRAL comparison of observed measurements — which leads on readiness/trend/stability (or 'tie' / 'not comparable' when close or unobserved); a measurement, not a safety or trust recommendation. For when you must choose between two MCP servers offering the same capability. An agent cannot self-produce this — it needs our accumulated longitudinal record of BOTH. Read-only, cost-zero, observed level, signed (verify_mcp_cert).
