Web3 MCP Server

Example Use Cases

• 1

  Query balances, transaction history, and on‑chain account details across Solana, Ethereum/EVM networks, Cardano, UTXO chains, XRP Ledger, and TON from a single RPC-style service.

• 2

  Send transactions, approve ERC‑20 spending, or perform token swaps (Jupiter on Solana, THORChain cross‑chain swaps) using private keys stored in environment variables for automated wallet operations.

• 3

  Configurable, minimal-surface blockchain tooling — selectively enable chains, use custom RPC/API keys (Blockfrost, TON Center), and get retry/backoff logic for rate-limited providers.

Description

Web3 MCP is an MCP server that provides unified RPC-style endpoints for common blockchain operations across many chains — balances, transactions, token transfers and approvals, swap quotes and cross-chain swaps. It is configured via environment variables (private keys, RPC URLs, API keys) and lets you selectively enable only the chain tools you need to reduce startup time and attack surface. The server integrates with third‑party providers (Blockfrost, TON Center, Jupiter, Nine Realms, etc.) and includes retry logic for rate limits, making it suitable for automations, agents, and tooling that need multi‑chain programmatic access.
