Mcp Blockchain Events

This server connects Claude to Crypto APIs' webhook infrastructure for monitoring on-chain events across EVM, UTXO, Solana, and XRP blockchains. You get two tools: one for creating webhook subscriptions (new blocks, confirmed transactions, address activity, token transfers) and another for managing them (list, get details, delete, activate). Each subscription sends real-time notifications to your callback URL when the specified event fires. You'll need a Crypto APIs account and key to use it. The package supports both stdio for local Claude Desktop integration and HTTP mode for shared deployments where each client can pass their own API key via headers. Useful when you need Claude to set up and manage blockchain monitoring without writing integration code yourself.
