Mcp Block Data
Connects Claude to Crypto APIs' block data endpoints across 18+ blockchains including Ethereum, Bitcoin, Polygon, and XRP. You get six core operations per chain type: fetch blocks by height or hash, list transactions within blocks, and query the latest mined blocks. Useful when you need to inspect on-chain block details without writing custom RPC calls or managing multiple blockchain client libraries. Supports both EVM chains (Ethereum, BSC, Arbitrum, Base, Optimism, Tron) and UTXO chains (Bitcoin, Litecoin, Dogecoin, Dash, Zcash). Requires a Crypto APIs account and API key to run.
