Web3 MCP Server

Example Use Cases

• 1

  Query balances, token holdings, transaction history and network info across multiple chains (Solana, Ethereum/EVM, Cardano, BTC/Litecoin/DOGE/BCH, XRP, TON, THORChain).

• 2

  Sign and send on-chain transactions (native tokens, ERC-20s, SPL tokens, Cardano UTXOs, XRP, TON) using private keys or mnemonics configured in environment variables for automation or wallet-backed actions.

• 3

  Swap quotes and execution (Jupiter for Solana, THORChain cross-chain swaps), token approvals, trustlines and other chain-specific operations via unified RPC endpoints.

Description

This MCP server bundles tools for interacting with many blockchains from a single process, offering RPC-style endpoints for common operations (balance checks, tx history, UTXO lookups, token transfers, swaps, approvals, etc.). It supports signing transactions using private keys or mnemonics provided via environment variables and can be configured to enable only the chains you need to reduce attack surface and startup time. The server integrates with third-party providers (Blockfrost, Jupiter, TON Center, THORNode, various UTXO providers) and allows custom RPC endpoints for reliability and rate limits.
