Base has introduced Base MCP, a system that enables AI assistants to initiate real on-chain operations within the network. Transactions can be created through Claude, ChatGPT, Codex, Cursor, and other models.

Introducing Base MCP

Your agent's new gateway to Base

→ Connect an agent to your Base Account
→ Enable it to swap, trade, and manage your portfolio
→ Use plugins from leading apps on Base

This tool connects a wallet with artificial intelligence via the Model Context Protocol (MCP), a data exchange protocol between models and external services. In this setup, the assistant can not only respond to requests but also create blockchain transactions based on user text commands.

Base MCP allows for:

  • fund transfers;
  • token swaps;
  • portfolio and transaction history viewing;
  • interaction with dapps within the Base ecosystem.

Initially integrated are Morpho, Moonwell, Aerodrome, Bankr, Avantis, Virtuals, and Uniswap, covering lending, DEX, perpetual futures, AI agents, and new tokens within the network.

Connection is made through the server https://mcp.base.org. The documentation also mentions Claude Web, Claude Desktop, Claude Code, and Hermes.

AI Generates — User Approves

Base emphasizes that the AI does not have access to private keys and cannot send transactions independently.

The assistant generates a transaction request, which is saved in the Base Account as pending confirmation. The user receives a link and manually approves or rejects the action. Only after this is the transaction signed and sent to the network.

Before confirmation, the system displays a simulation of balance and asset changes.

The company believes this mechanism reduces phishing risks and attacks through fake dapps: the transaction is generated within the wallet and AI pairing, rather than pulled from external web interfaces.

There are currently no independent audits or public security tests of the project.

Focus on Scalability

Base has opened documentation for creating custom plugins. Developers can outline instructions on how the AI should interact with external services, CLI, or other MCP servers.

After this, the assistant can transform responses from external services into on-chain actions — fund transfers, token swaps, message signing.

Essentially, MCP acts as a layer between AI and DeFi protocols on the Base network.

Examples of use include:

  • checking USDC balance;
  • viewing wallet addresses;
  • sending funds to an ENS address;
  • finding a USDC storage option with the highest yield and making a subsequent deposit.

In all scenarios involving fund movement, separate manual confirmation is required.

It is worth noting that in May, Keyrock referred to cryptocurrencies as the financial foundation for AI agents, as card payment infrastructure is poorly suited for microtransactions.
