OpenChainBench is a remote MCP server that gives an AI agent 3 tools, among them get_benchmark, list_benchmarks, query_prom. It answers at https://openchainbench.com/api/mcp/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Live, neutral benchmarks for public RPC latency, oracles, bridges, perp DEX, and prediction markets.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 Inputs: slug, chain, region |
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 h |
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 t Inputs: query, windowSec, steps |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://openchainbench.com/api/mcp/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
