Mcp Blockchain Fees

Connects Claude to Crypto APIs for blockchain fee estimation across UTXO chains like Bitcoin and Litecoin, EVM networks with EIP-1559 support, and XRP. You get fee recommendations at slow, standard, and fast tiers, plus gas estimation for EVM token transfers and contract calls. Useful when you're building wallet features, optimizing transaction costs, or need real-time fee data without hitting blockchain nodes directly. Requires a Crypto APIs account and key. Ships with stdio for local use or HTTP mode for multi-tenant deployments where each request brings its own API key.
