AI Agents Get Crypto Superpowers with Coinbase’s Base MCP

Coinbase’s Base gives AI agents new crypto wallet powers

Base has introduced Base MCP, a tool that allows users to connect their Base accounts to AI assistants. This enables them to manage their cryptocurrency transactions directly through a chat interface.

Summary

  • Base MCP lets AI agents swap, transfer, and track wallets from chat with user approvals.
  • The tool supports Uniswap, Morpho, Moonwell, and other Base apps while private keys stay protected.
  • Related x402 growth shows Coinbase expanding AI payments despite fresh security and malware concerns.

This Ethereum network, built with support from Coinbase, now offers a tool that lets users easily send and receive funds, swap tokens, check their account balances, review transaction history, and make payments up to 402 times faster.

Coinbase is increasing its focus on using artificial intelligence for cryptocurrency payments with this new launch. Essentially, Base is aiming to simplify crypto wallets with AI assistants, but will always require the user’s confirmation before any transaction goes through.

Base MCP brings wallets into AI chat

Base MCP lets you connect to AI assistants like ChatGPT, Claude, Codex, and Cursor. After connecting, you can ask the AI to manage your finances directly within the chat – track investments, send money, trade tokens, view transaction details, and even use certain Base applications, all without switching between apps.

Meet Base MCP – the new way to connect your AI agents to Base.

With Base MCP, your agents can:

* Link to your Base account
* Seamlessly swap, trade, and manage your digital assets
* Access powerful tools through plugins from top Base applications.

This is the future of intelligent, on-chain interactions.

The system prevents the AI from directly managing sensitive private keys. Instead, when the AI suggests a transaction, a review window pops up for the user to either approve or deny it. Base ensures users can see exactly how their assets will change before confirming any transaction.

Base adds DeFi apps to AI agent access

Base MCP initially supports a range of popular DeFi platforms like Moonwell, Morpho, Uniswap, Avantis, Bankr, Aerodrome, and Virtuals. This allows AI-powered tools to assist users with tasks such as finding the best lending rates, handling their crypto funds, trading tokens, researching new projects, and trading perpetual futures directly on the blockchain.

Base allows developers to create plugins that send transaction information to Base MCP, but users always approve transactions through their Base Account, ensuring the AI agent doesn’t have final control. This setup can help reduce some risks with crypto wallets, though it still requires well-written instructions, secure plugins, and thorough user checks.

x402 links Base MCP to AI payments

Base MCP now works with x402 payments, a system for handling very small payments made by automated programs and online services. Base’s official guides explain that AI assistants can use USDC on the Base and Base Sepolia networks to pay for APIs that accept x402 payments.

Coinbase has been developing its capabilities with projects like x402 and Agentic.market. Agentic.market allows AI agents to independently find and purchase services using USDC. Previously, x402 processed around 165 million transactions involving over 480,000 agents when it first launched.

AWS now allows its AI agents to make payments using USDC through a new integration with Coinbase x402 and Amazon Bedrock AgentCore Payments. This builds on existing support for the x402 standard from Stripe on Base and AllUnity, enabling more flexible payment options for AI agents.

Security concerns remain part of the rollout

As an analyst, I’ve been reviewing Base’s security protocols, and they emphasize that no transactions occur on the blockchain without the user’s direct permission. Importantly, they’ve stated their Multi-Party Computation (MCP) server doesn’t store or gain access to users’ private keys, which is a key component of their security model.

Despite advancements, keeping AI agents secure is still a major concern. A new report from experts at Google, Meta, Gray Swan AI, EmbraceTheRed, and several universities suggests that AI agents should be considered potentially unreliable parts of a system. To improve security, it’s important to clearly separate the commands they follow from the information they process.

This warning came after Socket discovered another security issue: a malware attack aimed at developers working with cryptocurrency and artificial intelligence. The attackers were attempting to steal sensitive information like wallet details, access keys for secure connections, and credentials for cloud services and APIs.
