On-chain AI: MCP server for Claude, ChatGPT and AI agents

Connect Claude, ChatGPT, Cursor or your own crypto AI agent to on-chain data and ask in plain words: who is behind a wallet, what it holds and made, where its money went, who is buying a token. 29 tools for Ethereum, BNB Chain, Base and HyperEVM on one free key, and in Claude Desktop no key at all.

Live stream

The live on-chain channel

Every transfer as it lands, filtered on the server.

1 live on-chain channel at wss://stream.vike.io/v1/stream/onchain: chain.transfers, filtered by wallet, token, chain, min_usd, min_amount, entity, wallet_type, contract. Your agent reads what it sent with stream_events. Filters, a real event and code →

FAQ

On-chain AI and MCP FAQ

Is there an MCP server for on-chain crypto data?

Yes: https://data.vike.io/mcp, 29 tools for wallets, labels, tokens, transactions, the live stream and alerts on Ethereum, BNB Chain, Base and HyperEVM. Claude Desktop signs in with OAuth and needs no key; other clients send a free key in X-API-KEY.

Can I build a crypto AI agent on it?

Yes. Any agent that speaks MCP over streamable HTTP calls the same 29 tools; a script can run any of them with vike-data call <tool> --args '{…}', and every tool has a REST route on the same key. A tool call costs 0 to 5 credits; nothing is billed.

Which blockchains does it cover?

Ethereum, BNB Chain, Base and HyperEVM (ethereum, bsc, base, hyperevm). Wallets, labels, transfers and token holders on all four; the live stream carries transfers on all four too.

Is there a free on-chain MCP server?

Yes, this one: one free key, nothing billed, with address labels and where each label comes from, wallet positions and PnL, token holders, the money trail and live transfers, in Claude, ChatGPT, Cursor or your own agent.

Is there an on-chain CLI?

Yes: npm install -g @vike-io/cli, then vike-data wallet …, vike-data token …, vike-data labels and vike-data stream onchain. vike-data install --claude adds the skill that teaches Claude Code to use it.
