Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable src/arena/store.js:23, src/arena/house.js:62, src/free-pulse.js:20 
  if (raw) return path.isAbsolute(raw) ? raw : path.join(ROOT, raw);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

arena
arena_current_round
FREE: current Crypto Pulse Prediction Arena round timing (open/cutoff/close UTC), whether entries are accepted, entry counts, and top of leaderboard. No payment.
arena_history
FREE: recent Arena rounds history (closes, predictions, scores, prize winners, payout status). Optional limit (default 10). For CSV use GET /v1/arena/history?format=csv.
arena_leaderboard
FREE: arena leaderboard. Default is the current daily round. Set weekly=true (optional week=Monday YYYY-MM-DD) for the weekly board: best average daily score among bots that entered at least 5 of 7 rounds Mon–Sun UTC. Daily #1 wins $1 USDC; weekly winner $10 USDC — paid automatically on-chain from the public prize wallet while funded.
arena_prize_wallet
FREE: public prize wallet address, live USDC/SOL balances, autopay on/off, and recent payout history with Solscan links. No secrets.
arena_results
FREE: scored or in-progress Arena round results — CoinGecko closing prices used for scoring, every prediction with abs % error, leaderboard with house:true/eligible flags, prize-eligible winner, and payout status with Solscan tx links when paid.
arena_rules
FREE Crypto Pulse Prediction Arena rules: daily UTC rounds for BTC/ETH/SOL close predictions, free entry (no purchase necessary), scoring by average abs % error, sponsor-funded prizes paid automatically on-chain from the public prize wallet while funded ($1 daily / $10 weekly). Includes prize wallet address + recent payouts. Server never handles bot private keys.
arena_submit_prediction
FREE: submit or update a signed BTC/ETH/SOL price prediction for the current (or given) arena round. Pass a pre-signed payload — the server never receives private keys. Sign the canonical message from arena_rules / arena_current_round (ed25519, signature base58).
market
get_market_pulse
Live full pulse ($0.02 USDC on Solana via x402 after free quota). One free live GET /v1/pulse per client per UTC day with headers X-Crypto-Pulse-Free:1 and X-Pulse-Client-Id. Bare GET still returns HTTP 402 for x402 discovery. This MCP tool returns payment requirements + HTTP URL. Free stale preview: get_market_sample.
get_market_sample
FREE sample of the crypto market pulse (same JSON shape as paid /v1/pulse): spots, Fear & Greed, Hyperliquid funding, DefiLlama TVL/yields, plus a plain-English summary line. Data may be up to 15 minutes old. Use get_market_pulse for live paid data.
get_market_spots
PAID live BTC/ETH/SOL/HYPE spot prices only ($0.005 USDC). Returns payment requirements + HTTP URL for x402. Prefer get_market_pulse when you also need Fear & Greed, funding, or DeFi. Free preview: get_market_sample.

Crypto Pulse — questions

Answers built from our own checks of this server.

What can Crypto Pulse do?
It exposes 10 tools, read directly from the server on our last check. Among them: arena_current_round, arena_history, arena_leaderboard, arena_prize_wallet, arena_results, arena_rules and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Crypto Pulse mostly used for?
Its tools cluster around arena and market. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Crypto Pulse working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 402 ms. The bar chart above shows every period we have measured.
How do I connect Crypto Pulse?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Crypto Pulse need an API key?
No. Crypto Pulse completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Crypto Pulse?
It answers our handshake in 402 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Crypto Pulse open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at cryptopulseapi.com, which runs on its operator's own terms.
