}Provides blockchain data access and token operations across 60+ EVM-compatible networks including Ethereum, Arbitrum, Optimism, and Base. Features automatic ENS resolution and smart contract interaction with ABI fetching.
EVM Blockchain is a community-built MCP server published by mcpdotdirect that provides AI assistants with tools and capabilities via the Model Context Protocol. EVM Blockchain connects with Ethereum, Optimism, Arbitrum, and Base for token transfers, smart contract data, and ENS na It is categorized under developer tools. This server exposes 28 tools that AI clients can invoke during conversations and coding sessions.
You can install EVM Blockchain in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.
A comprehensive Model Context Protocol (MCP) server that provides blockchain services across 60+ EVM-compatible networks. This server enables AI agents to interact with Ethereum, Optimism, Arbitrum, Base, Polygon, and many other EVM chains with a unified interface through 22 tools and 10 AI-guided prompts.
The MCP EVM Server leverages the Model Context Protocol to provide blockchain services to AI agents. It supports a wide range of services including:
All services are exposed through a consistent interface of MCP tools, resources, and prompts, making it easy for AI agents to discover and use blockchain functionality. Every tool that accepts Ethereum addresses also supports ENS names, automatically resolving them to addresses behind the scenes. The server includes intelligent ABI fetching, eliminating the need to know contract ABIs in advance.

# Clone the repository
git clone https://github.com/mcpdotdirect/mcp-evm-server.git
cd mcp-evm-server
# Install dependencies with Bun
bun install
# Or with npm
npm install
The server uses the following environment variables. For write operations and ABI fetching, you must configure these variables:
You can configure your wallet using either a private key or a mnemonic phrase:
Option 1: Private Key
export EVM_PRIVATE_KEY="0x..." # Your private key in hex format (with or without 0x prefix)
Option 2: Mnemonic Phrase (Recommended for HD Wallets)
export EVM_MNEMONIC="word1 word2 word3 ... word12" # Your 12 or 24 word BIP-39 mnemonic
export EVM_ACCOUNT_INDEX="0" # Optional: Account index for HD wallet derivation (default: 0)
The mnemonic option supports hierarchical deterministic (HD) wallet derivation:
m/44'/60'/0'/0/{accountIndex}EVM_ACCOUNT_INDEX allows you to derive different accounts from the same mnemonicWallet is used for:
transfer_native tool)transfer_erc20 tool)approve_token_spending tool)write_contract tool)sign_message tool)sign_typed_data tool)⚠️ Security:
export ETHERSCAN_API_KEY="your-api-key-here"
This API key is optional but required for:

The server uses the following default configuration:
These values are hardcoded in the application. If you need to modify them, you can edit the following files:
src/core/chains.tssrc/server/http-server.tsYou can run the MCP EVM Server directly without installation using npx:
# Run the server in stdio mode (for CLI tools)
npx @mcpdotdirect/evm-mcp-server
# Run the server in HTTP mode (for web applications)
npx @mcpdotdirect/evm-mcp-server --http
Start the server using stdio (for embedding in CLI tools):
# Start the stdio server
bun start
# Development mode with auto-reload
bun dev
Or start the HTTP server with SSE for web applications:
# Start the HTTP server
bun start:http
# Development mode with auto-reload
bun dev:http
Connect to this MCP server using any MCP-compatible client. For testing and debugging, you can use the MCP Inspector.

💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
