Base Network MCP Server – Overview

The Base Network MCP Server bridges the gap between natural‑language AI assistants and blockchain operations on the Base network. By exposing a set of high‑level tools over the Model Context Protocol, it lets developers empower chat‑based agents to create wallets, query balances, and execute transactions without writing Solidity or handling raw JSON‑RPC calls. This is especially valuable for rapid prototyping, educational demos, and integrating blockchain interactions into existing AI workflows.

At its core, the server implements three primary capabilities: wallet management, balance checking, and transaction execution. The tool parses free‑form text such as “Send 0.5 ETH to 0x1234…” and translates it into the appropriate RPC calls, returning a structured response that includes transaction hashes or balance figures. The tool generates a new Base wallet, optionally assigning a user‑friendly name, while retrieves the current ETH balance of any specified wallet. These tools are designed to be straightforward for an LLM to invoke, allowing the assistant to handle a full end‑to‑end workflow: “Create a new wallet named Alpha, check its balance, and send 1 ETH to another address.”

The server supports both Base Mainnet and the Sepolia testnet, making it suitable for production deployments as well as sandbox testing. Configuration is simple: the provider URL and a private key are supplied via environment variables, with an optional gas‑price override. Because the MCP stack is transport‑agnostic, the server can be paired with any client—Claude Desktop, custom web UIs, or command‑line tools—using the same protocol definition.

Real‑world use cases include building a conversational crypto wallet, integrating blockchain payments into customer support bots, or creating interactive tutorials that let users learn Ethereum operations through dialogue. By abstracting away the low‑level RPC details, developers can focus on crafting natural language experiences while still maintaining full control over security and network settings. The Base Network MCP Server thus delivers a powerful, developer‑friendly entry point for embedding blockchain logic into AI‑driven applications.
