Live, neutral benchmarks for public RPC latency, oracles, bridges, perp DEX, and prediction markets.
OpenChainBench MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Live, neutral benchmarks for public RPC latency, oracles, bridges, perp DEX, and prediction markets.
OpenChainBench publishes one benchmark at a time, each shipping with the harness that produces its data. The goal is to make performance an observable property of crypto infra, measured in the open, by anyone who wants to add a provider or a metric.
Once OpenChainBench is connected, these are the calls the assistant has available:
Discussions — github.com/ChainBench/OpenChainBench/discussionsWikidata — Q140172649Endpoint — AudienceRoute — What lives therepnpm on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. OpenChainBench's toolset — Discussions, Wikidata, Endpoint and 1 more — is a fair guide to whether it matches your workflow. It is maintained by Flotapponnier; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
