Mcp Utils

This connects Claude to Crypto APIs' utility endpoints for working with blockchain addresses and transactions across UTXO chains (Bitcoin, Litecoin, Dogecoin, Dash, Zcash), EVM networks, XRP, and Tron. You get address validation, raw transaction decoding, XRP X-Address encoding/decoding, and HD wallet address derivation from xPub/yPub/zPub keys without needing to sync a node. Particularly handy for the derivation tool, which generates up to 10 addresses per call from extended public keys. Requires a Crypto APIs account and API key. Available as a local stdio/HTTP server or via their hosted endpoint at ai.cryptoapis.io/mcp. Ships with sibling packages for their other API products if you need blockchain data queries or webhook management.
