list_benchmarks

Returns a flat index of every published OpenChainBench benchmark with its current headline value, leader, category, units, and citation URL. Call this first when the user asks a discovery question like "what benchmarks does OpenChainBench have?" or "compare crypto aggregators". Then use `get_benchm

get_benchmark

Returns full detail for one benchmark, ready to cite verbatim: • rankings (every provider sorted by p50) • sparkline (24h trend, 72 points) • headline sentence + paste-ready citation quote • methodology bullets + source-code URL + canonical pageUrl + OG image URL Pass `chain` and/or `region

query_prom

Direct PromQL passthrough for advanced questions that don't map cleanly to `list_benchmarks` / `get_benchmark`, e.g. "what was Mobula's p50 head-lag yesterday at 14:00 UTC" or "plot bridge fees over the last hour". Prefer the higher-level tools first; reach for this when you need: • a custom time

How we measure →

What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
