Onchain Data MCP

An MCP server that allows AI assistants to read live blockchain data for EVM chains and Solana. It supports checking wallet balances, confirming payments, detecting scams, following transaction history, retrieving token prices, and looking up tokenized stocks. It aggregates data from approximately 30 providers, prioritizing free services, and only reads data without holding user keys.
