Usage
With Claude Desktop
Claude Desktop is a popular LLM client that supports the Model Context Protocol. You can connect your Base MCP server to Claude Desktop to perform blockchain operations via natural language commands.
You can add MCP servers to Claude Desktop via its config file at:
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json
To add your Base MCP server to Claude Desktop, add the following configuration to the mcpServers object in the config file:
{
"mcpServers": {
"base": {
"command": "npx",
"args": [
"-y",
"base-network-mcp-server"
],
"env": {
"BASE_PROVIDER_URL": "https://api.developer.coinbase.com/rpc/v1/base/YOUR_API_KEY",
"WALLET_PRIVATE_KEY": "your_private_key_here"
},
"disabled": false,
"autoApprove": []
}
}
}
Configuration
- BASE_PROVIDER_URL: The URL of the Base network provider (Mainnet or Sepolia)
- WALLET_PRIVATE_KEY: Your wallet private key for authentication and transaction signing
- DEFAULT_GAS_PRICE: (Optional) Default gas price in Gwei
Programmatically (custom MCP client)
If you're building your own MCP client, you can connect to the Base MCP server programmatically using your preferred transport. The MCP SDK offers built-in stdio and SSE transports.
