OpenChainBench — Claude Code MCP server: crypto infra benchmarks
Lets your agent pull live benchmarks for crypto infrastructure: RPC latency, oracles, bridges, perp DEXes and prediction markets.
claude mcp add --transport http openchainbench https://openchainbench.com/api/mcp/mcpWhat OpenChainBench does
OpenChainBench measures crypto infrastructure and publishes the numbers: RPCs, oracles, bridges, aggregators, price feeds, cross-chain messaging, perp DEXes, prediction markets. Every provider is scored on the same metric under the same conditions. Data ships under CC-BY-4.0, the harnesses under MIT.
The MCP server exposes that data to your agent through three tools — list_benchmarks, get_benchmark and query_prom — plus the openchainbench://benchmark/{slug} resource. It runs over HTTP at https://openchainbench.com/api/mcp/mcp, so there is no local process to start. In Claude the whole setup is claude mcp add --transport http openchainbench https://openchainbench.com/api/mcp/mcp.
Benchmarks get refreshed, and each one carries a freshness value, so check the as-of date before you quote a figure. Providers that appear in a ranking can also submit pull requests, which is a reason to read the methodology rather than just the top row.
What it helps with
- compare RPC provider latency on one shared metric
- pick a bridge or oracle for a specific chain
- pull a live benchmark figure into an agent answer
- read the methodology before citing a number
- find every benchmark a given product appears in
Example prompts for the agent
- List the OpenChainBench benchmarks for RPCs
- Which provider leads head lag in the aggregator-head-lag benchmark?
- Fetch the methodology for the bridges benchmark and tell me when it was last updated

Questions about OpenChainBench
How do I install OpenChainBench in Claude Code?
Run claude mcp add --transport http openchainbench https://openchainbench.com/api/mcp/mcp. It uses the HTTP transport, so nothing runs locally.
What does OpenChainBench do?
It serves live crypto infrastructure benchmarks to your agent: RPCs, oracles, bridges, aggregators, perp DEXes and prediction markets. The MCP tools are list_benchmarks, get_benchmark and query_prom.
Does the server need an API key?
The connection points at https://openchainbench.com/api/mcp/mcp, and no key appears in the setup commands.
