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

The tool links a wallet with artificial intelligence through Model Context Protocol (MCP), a protocol for data exchange between models and external services. In this configuration, the assistant can not only respond to requests but also form blockchain transactions based on the user’s text command.
Base MCP offers:
- fund transfers;
- token exchanges;
- portfolio and transaction history viewing;
- interaction with dapps within the Base ecosystem.
Initially, Morpho, Moonwell, Aerodrome, Bankr, Avantis, Virtuals, and Uniswap are integrated. This covers lending, DEX, perpetual futures, AI agents, and new tokens within the network.
Connection is made via the server https://mcp.base.org. The documentation also mentions Claude Web, Claude Desktop, Claude Code, and Hermes.
AI Forms — User Signs
Base emphasizes that AI does not have access to private keys and cannot send transactions independently.
The assistant forms an operation request, which is saved in the Base Account as pending confirmation. The user receives a link and manually approves or rejects the action. Only then is the transaction signed and sent to the network.
Before confirmation, the system shows a simulation of balance and asset changes.
The company believes this mechanism reduces phishing risks and attacks through fake dapps: the transaction is formed within the wallet and AI connection, not pulled from external web interfaces.
There are currently no independent audits or public security tests of the project.
Focus on Expandability
Base has opened documentation for creating custom plugins. Developers can describe instructions on how AI should work with external services, CLI, or other MCP servers.
After this, the assistant can convert responses from third-party services into on-chain actions — fund transfers, token exchanges, message signing.
Effectively, MCP becomes a layer between AI and DeFi protocols in the Base network.
Examples of use include:
- checking USDC balance;
- viewing wallet addresses;
- sending funds to an ENS address;
- finding the USDC storage with the highest yield and making a deposit.
In all scenarios involving fund movement, separate manual confirmation is required.
In May, Keyrock described cryptocurrencies as the financial foundation for AI agents, as payment card infrastructure is poorly suited for microtransactions.
