VeChain MCP Server

VeChain MCP Server is a blockchain integration tool for the VeChain network that enables querying on-chain data, managing wallets, and executing token transactions. Key capabilities: - Query on-chain data including account details, transactions, blocks, and priority fee suggestions via the Thor REST API for both Mainnet and Testnet - Create VeChain wallets with mnemonic and key generation, plus sign messages, certificates, and raw transactions - Execute token operations including balance checks, transfers of native currency or ERC20 tokens, and approval management - Sign EIP-712 typed data structures and handle token allowances for DeFi interactions - Search the official VeChain documentation with direct links to relevant pages - Powered by GOAT SDK for comprehensive wallet and token management functionality
