How to Set Up and Use Base Network
Base MCP connects AI assistants to the Base blockchain network and Coinbase's wallet infrastructure, enabling on-chain operations including sending tokens, swapping assets, signing messages, executing smart contract interactions, and making x402 micropayments for API access. The server operates across 7 mainnets (Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Ethereum) and Base Sepolia testnet, with every write action requiring explicit user approval via Base Account before execution. Developers building AI agents with crypto capabilities use it to give Claude a real programmable wallet without managing private keys directly.
Prerequisites
- A Base Account (smart wallet) at https://base.org — required for approving on-chain transactions
- No API key required — authentication uses OAuth via Base Account
- An MCP client such as Claude Desktop, Claude Code, or Cursor
- For testnet use: Base Sepolia ETH available from a faucet
Create a Base Account
Navigate to https://base.org and create a Base Account (smart wallet). This account will be used to approve all transactions requested by the AI assistant.
Add Base MCP via Claude Code (recommended)
For Claude Code users, add the hosted Base MCP server with a single command. This connects to the mcp.base.org remote endpoint without any local installation.
claude mcp add --transport http base-mcp https://mcp.base.orgConfigure Claude Desktop for Base MCP
For Claude Desktop, add the Base MCP server using the remote HTTP URL. No environment variables or API keys are needed.

}
}Authorize Base MCP via Base Account
On first use, Claude will prompt you to authorize the connection. Click the authorization link and approve access in your Base Account. This grants the MCP server permission to propose transactions to your wallet.
Verify the connection
After authorization, check that the Base MCP tools are active and the server shows the correct tool count.

Client configuration
Minimal config for Claude Desktop pointing to the hosted Base MCP endpoint. No credentials needed in the config file — authentication is handled via OAuth through Base Account.

}Prompts to try
These prompts work after Base MCP is authorized with your Base Account.
- "Send 0.01 ETH to vitalik.eth on Base"
- "Swap 10 USDC for ETH on Base mainnet"
- "Check the current balance of my Base Account"
- "Deploy a simple ERC-20 token contract on Base Sepolia for testing"
- "Make an x402 payment to access the premium API endpoint at https://api.example.com/data"Troubleshooting Base Network
Authorization link does not open or Base Account cannot be found
Ensure you have created a Base Account at https://base.org before attempting to authorize. The OAuth flow requires a browser to complete. If the link expires, restart the MCP server connection and try again.
Transaction is proposed but never executes
All write operations require explicit approval in the Base Account interface. Check your Base Account notifications for a pending approval request. Transactions will not execute without user confirmation — this is by design.
npx base-mcp or npm install base-mcp fails
The legacy npm package (base-mcp) has been deprecated and should not be used. Use the hosted remote server at https://mcp.base.org instead, as documented in the current Base AI agents docs at https://docs.base.org/ai-agents.
