evmcp

EVM + MCP — give your AI assistant blockchain superpowers.

MCP server providing real-time access to on-chain data across Base, Optimism, Avalanche, Celo, and Arbitrum, with companion smart contracts deployed on-chain for batch queries and cross-chain data.

How it Works

EVMCP implements the Model Context Protocol (MCP), a standard that lets AI assistants call external tools. When connected, your AI assistant gains 28 read-only blockchain tools it can invoke to query balances, decode transactions, compare gas prices, and more across five EVM chains.

What sets EVMCP apart is its companion smart contracts — four Solidity contracts deployed on Avalanche and Celo that enable batch queries via Multicall3, an on-chain tool registry, event aggregation, and cross-chain balance caching. The MCP server reads from these contracts; all write operations are performed separately by an admin CLI.

Quick Start

With Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

"mcpServers": { "evmcp": { "command": "npx", "args": ["-y", "evmcp"], "env": { "ALCHEMY_API_KEY": "your_key_here" } } } }

With Claude Code

claude mcp add evmcp -- npx -y evmcp

Companion Contracts

Four Solidity contracts are deployed on Avalanche and Celo. The MCP server reads from these contracts to provide batch queries, on-chain tool metadata, and cross-chain data. Base and Optimism deployments are planned.
