Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability86
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 12764 tokens (~57/item across 222 items; 3 tools + 219 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the OpenChainBench MCP server?

OpenChainBench is a hosted endpoint at https://openchainbench.com/api/mcp/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_benchmark ~350

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` to scope the result to a sub-slice when the benchmark declares those dimensions (e.g. aggregator-head-lag exposes chain=base|bnb|solana, region=us-east|eu-west|ap-southeast). Both args are optional; omit them for the global aggregate. Example usage: • User: "who's the fastest crypto data aggregator on Base?" → get_benchmark({ slug: "aggregator-head-lag", chain: "base" }) • User: "how much does it cost to bridge $300 cross-chain?" → get_benchmark({ slug: "bridge-fee" }) Drafts return { error: "unknown_slug" }. Cite the returned `pageUrl` and use `quote` as the attribution line in your answer.

NameTypeReqDescription
chainstring–Optional chain filter, e.g. 'base', 'solana', 'bnb'. Only honored when the bench declares chain dimensions.
regionstring–Optional region filter, e.g. 'us-east', 'eu-west', 'ap-southeast'. Only honored when the bench declares region dimensions.
slugstringyesBenchmark slug from list_benchmarks. e.g. 'aggregator-head-lag', 'bridge-quote-latency', 'l1-finality'.

list_benchmarks ~123

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_benchmark` for the specific slug(s) the answer needs. Returns one line per bench: { slug, title, category, metric, unit, value, leader, headline, url, asOf } Drafts are filtered out: only live benchmarks appear.

Input schema present but exposes no named parameters.

query_prom ~694

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 window (instant query at a specific point, or range) • a derived metric (rates, ratios, deltas) • a histogram bucket aggregation across chains/regions Allowed metric namespaces (one prefix per OCB bench family): head_lag_seconds (aggregator latency) bridge_quote_latency_ms*, bridge_cost*, bridge_fees*, bridge_fix_fee*, bridge_execution_latency_ms*, bridge_e2e_latency_ms*, bridge_success_total, bridge_reverts_total, bridge_refunds_total, bridge_stuck_total, bridge_refund_latency_ms*, bridge_realized_output_usd, bridge_quote_slippage_usd, bridge_exec_gas_usd, bridge_gas*, bridge_output*, bridge_estimated_time*, bridge_quote_success l1_finality_*, l2_block_time_* metadata_coverage_*, metadata_api_latency_*, network_coverage_*, networks_supported, wallet_labels_* perp_fees_*, perp_funding_*, perp_venue_*, perp_execution_*, perp_liq_*, perp_realized_vol_*, ocb_buyback_*, ocb_oracle_*, ocb_validator_*, ocb_chain_* gas_error_*, gas_predicted_*, gas_realized_*, gas_oracle_* peg_* (stablecoin peg, both variants) solana_landing_* (TX landing observational + active) rpc_latency_*, rpc_call_total, rpc_health, rpc_archive_depth_supported relay_*, per_swap_margin_usd (bridge revenue) Queries referencing other metrics (operational/internal ones like `up`, `scrape_*`, `process_*`, `go_*`, `wallet_balance_*` or any label- enumeration shape) are refused with `{error, reason}`. Example: instant p50 over 1h for Mobula head-lag on Base: query_prom({ query: "quantile_over_time(0.5, head_lag_seconds{aggregator=\"mobula\",chain=\"base\"}[1h]) * 1000" }) Example: 7-day sparkline of average bridge fees: query_prom({ query: "avg_over_…

NameTypeReqDescription
querystringyesPromQL expression referencing published benchmark metric prefixes only. Function names, label keys, and quoted label values are fine; bare metric names must be allowlisted.
stepsinteger–Number of samples for a range query (2 to 360). Default 60. Step duration = windowSec / steps.
windowSecinteger–If set, run a range query over the last N seconds (max 7 days = 604800). Omit for an instant query.

Common questions

What is the OpenChainBench MCP server?

OpenChainBench is an MCP server listed in the public MCP registry as io.github.Flotapponnier/openchainbench. Live, neutral benchmarks for public RPC latency, oracles, bridges, perp DEX, and prediction markets. This page covers its hosted endpoint (https://openchainbench.com/api/mcp/mcp).

Is the OpenChainBench MCP server safe to use?

OpenChainBench scores 83 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the OpenChainBench MCP server expose?

OpenChainBench exposes 3 tools: list_benchmarks, get_benchmark, query_prom. Their descriptions and schemas cost roughly 1,167 tokens of context every time the server is loaded.

Does the OpenChainBench MCP server require authentication?

No. We connected to OpenChainBench without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the OpenChainBench MCP server still maintained?

OpenChainBench is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
