Base has launched Base MCP, allowing AI assistants to perform on-chain operations, enhancing user interaction with blockchain technologies.
Base has launched a new system named Base MCP, which empowers AI assistants to perform genuine on-chain operations within its network. This functionality allows transactions to be initiated through various AI models, including Claude, ChatGPT, Codex, and Cursor.
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 innovative tool links an AI wallet to the network via the Model Context Protocol (MCP), facilitating data exchange between AI models and external services. As a result, the assistant can generate blockchain transactions based on user commands.
Base MCP enables users to:
- transfer funds;
- swap tokens;
- view portfolio and transaction history;
- interact with decentralized applications (dapps) within the Base ecosystem.
Initial integrations include platforms like Morpho, Moonwell, Aerodrome, Bankr, Avantis, Virtuals, and Uniswap, covering sectors such as lending, decentralized exchanges (DEX), and perpetual futures.
Connections are established through the server, with documentation available for Claude Web, Claude Desktop, Claude Code, and Hermes.
AI Requests Require User Approval
Base clarifies that the AI does not have direct access to private keys and cannot independently send transactions. Instead, the assistant creates a transaction request that is stored as pending in the user's Base Account. Users are then notified via a link to manually approve or deny the action before it is signed and submitted to the network.
Prior to confirmation, the system provides a simulation of potential balance and asset changes, aiming to mitigate risks of phishing and attacks through fake dapps by ensuring that transactions are generated within the secure wallet and AI pairing.
Currently, there are no independent audits or public security assessments available for this project.
Emphasis on Scalability
Base has also made documentation accessible for developers to create custom plugins, allowing them to define how AI interacts with external services or other MCP servers. This capability enables the assistant to convert responses from external sources into actionable on-chain operations, including fund transfers and token swaps.
Examples of potential use cases include:
- checking USDC balances;
- viewing wallet addresses;
- sending funds to an ENS address;
- identifying high-yield USDC storage options and making deposits.
In all scenarios involving fund transfers, user confirmation is mandatory. Notably, Keyrock recently highlighted cryptocurrencies as the key financial infrastructure for AI agents, given that traditional card payment systems struggle with microtransactions.
