Crypto market data in your AI client. Over MCP.
DEBYKO runs a remote MCP server for crypto market data at https://mcp.debyko.com/mcp: perpetual futures on 16 venues, each value with the venue's time, its status and its age. Claude, ChatGPT, Cursor or any MCP client.
What is an MCP server for crypto market data?
MCP (Model Context Protocol) lets an AI client call tools on a server. DEBYKO's server gives it read-only tools over 16 perpetual futures venues: venues, instruments, snapshots, history, screen, candles, anchor_proof and account, plus the Agent tools that save alert rules with you.
No tool places an order, moves money or changes your plan.
How do I connect it?
- Add a custom connector (Claude, ChatGPT) or an MCP server (Cursor, Claude Code, Codex) with the address https://mcp.debyko.com/mcp.
- Sign in with a DEBYKO account when the client asks. A new email address opens a Free account, no card.
- Or send Authorization: Bearer <key> from a client that takes headers.
Six prompts that work as written.
- Which venues have the highest and lowest BTC funding over 8 hours right now?
- Show ETH open interest on every venue, converted to ETH, with the age of each figure.
- Was any SOL funding rate stale in the last hour? Name the venue and the reason.
- What was the BTC mark on Kraken Futures at 2026-10-01 09:00 UTC, as DEBYKO had it then?
- List the perpetuals where at least two venues pay negative funding now.
- Tell me in Telegram when BTC funding on two venues goes below zero.
Other servers and what DEBYKO is.
- CoinGecko: CoinGecko publishes prices and market data for cryptoassets and offers an API and an MCP server for it.
- CoinGlass: CoinGlass publishes crypto derivatives analytics and an API for funding, open interest and liquidations.
- Bitquery: Bitquery provides blockchain and on-chain trading data through GraphQL APIs and streams.
- Stored as each venue published it: every value keeps the venue's time and the time DEBYKO received it.
- A status instead of a stale number: a value past its horizon comes back as stale with its reason, without the number.
- 16 perpetual futures venues side by side, with funding over 8 h from each listing's interval.
- Sealed daily on Base: a Merkle root of each day's rows, which anyone can check a row against.
- A remote MCP server for AI clients, and DQL for questions across venues.
- x402: pay per request in USDC on Base, without an account.
Questions people ask.
Is the DEBYKO MCP server free?
A Free account works with it and needs no card. Its daily request limit is on the pricing table; paid plans add venues, history and Agent rules.
Which AI clients work with it?
Any client that speaks MCP over Streamable HTTP: Claude, ChatGPT, Cursor, Claude Code, Codex and others.
Can the server trade for me?
No. The data tools only read. The Agent tools save rules that send you a message; none places an order.
Can I pay without an account?
Yes, through the API: x402 takes USDC on Base per request.
