list_benchmarksLABSCO SUMMARY
The harness ships with the number.
That is the difference from a vendor comparison page: every benchmark's measuring code is in the repository, and pull requests are accepted from anyone including the providers being measured. For an agent, the practical consequence is that get_benchmark returns methodology alongside rankings — so a claim can be qualified rather than quoted flat. query_prom goes below the published view when the summary is not the cut you need.
What it is
The MCP surface of OpenChainBench, a public benchmark project for crypto infrastructure. Each benchmark ships with the harness that produced its numbers, and the server lets an agent list what is measured, read one benchmark's rankings and methodology, and query the underlying metrics store directly.
What you get
list_benchmarksenumerates what is measuredget_benchmarkreturns one benchmark's full rankings, methodology and a paste-ready quote with attributionquery_promreaches the metrics store behind the published figures- A resource at
openchainbench://benchmark/{slug}for reading a benchmark as context - 94 live benchmark specs across 8 categories — RPCs, Trading, Aggregators, Bridges, Blockchains, RWA, Explorers and NFT APIs — measured by 50 self-contained Go harnesses
- Data is CC-BY-4.0 and every figure carries a citation URL, so a number quoted in a report can be traced
Requirements
Nothing to install. It is a remote server over Streamable HTTP at https://openchainbench.com/api/mcp/mcp, published as io.github.chainbench/openchainbench version 1.0.0, and no key is mentioned. If you want to run the site or a harness yourself, the repository is a pnpm project: pnpm install, pnpm dev for the site on port 3000, pnpm validate to check a benchmark spec against its schema.

USE CASES
01
Choosing an RPC provider on evidence
Read the current rankings for the relevant benchmark plus how it was measured.
02
Finding out what is even measured
List the benchmarks across the categories before assuming a metric exists.
03
Citing a figure in something you publish
Take the headline sentence and citation URL rather than paraphrasing a leaderboard.
04
Asking a question the published view does not answer
Query the metrics store directly for the slice you need.
