Crypto & Web3 MCP servers
On-chain data is public but hostile to read. These servers let an agent query blockchains, wallets, and protocols directly, turning addresses and transactions into answers. Treat anything that can sign or send with extreme care.
What engineers use them for
- Look up balances, transactions, and token movements
- Monitor contract activity worth reacting to
- Analyze wallet history for a report
- Track protocol metrics without a dashboard
