Base has introduced a new tool that links cryptocurrency wallets with artificial intelligence agents, as the Coinbase-backed network moves deeper into AI-driven payments and onchain automation.
The product, called Base MCP (Model Context Protocol), allows users to connect their Base Account to AI systems such as ChatGPT, Claude, Codex, and Cursor. Through a chat interface, users can request token swaps, transfers, balance checks, and transaction reviews without leaving the conversation.
The release marks a shift in how crypto wallets interact with software. Instead of manual navigation across decentralized apps, users can rely on prompts that trigger actions across the Base ecosystem.

A unified chat interface for crypto activity
Base said the system enables users to manage multiple blockchain actions from a single interface. After authentication, an AI agent can propose actions such as sending funds or executing trades. The user then receives a link that opens a Base Account window for approval.
The design keeps final control in human hands. Each request shows simulated asset changes before confirmation. Users can reject any transaction before execution.
The company stated that the agent does not access private keys. Transactions remain unsigned until the user reviews them in the Base Account environment.
Lincoln Murr, head of AI product for Coinbase, told Fortune that “unlike siloed agentic wallets that only live in a terminal, your Base Account travels with you — trades, history, and portfolio sync whether you’re in-agent or in the Base App.”
Ecosystem access expands through plugins
Base MCP launches with integrations across several decentralized finance platforms. These include Morpho and Moonwell for lending, Uniswap and Aerodrome for swaps and liquidity, and Avantis for perpetual trading. Bankr and Virtuals add access to token and agent-related activity.
These plugins extend the role of AI agents beyond simple wallet functions. Users can explore lending markets, manage liquidity positions, and review token launches through direct prompts.
Developers can also create custom plugins. Base documentation outlines a process where developers define how an agent retrieves unsigned transaction data. The system then routes that data to Base MCP for user approval.
This structure keeps execution separate from instruction. The agent prepares the request, while the user signs it.
Payment ambitions tied to x402 protocol
The launch also supports the x402 payment standard, which Coinbase introduced in 2025. The protocol targets small crypto payments made by AI agents and web services.
Base said MCP can handle x402-enabled transactions, which often use USDC on Base or Base Sepolia. The company has positioned this model as a foundation for a micro-transaction economy powered by autonomous systems.
However, current usage remains limited. Data from x402scan shows about $1.1 million in volume over the past 30 days. That figure reflects early adoption rather than widespread deployment.
Security concerns remain under scrutiny
Base emphasized that “nothing happens onchain without your explicit approval.” The company also noted that MCP servers do not store private keys and only hold transaction requests until user review.
Despite these safeguards, concerns about AI agent security persist. A recent research paper from Google and several universities argued that AI agents should be treated as untrusted system components. The researchers warned that agents must separate instructions from untrusted data to prevent manipulation.
Another case raised similar concerns. Developer platform Socket reported malware that targeted crypto developers by injecting hidden instructions into AI coding tools. The attack aimed to extract sensitive information such as wallet data and API keys.
These incidents highlight risks tied to automation in financial systems. Base has framed its approval flow as a safeguard against such threats, though responsibility still rests with users to verify each action.
A step toward AI-driven crypto use
Base MCP reflects a broader effort to simplify blockchain interactions through AI. The system reduces reliance on multiple apps and interfaces, while it introduces a model where agents assist with execution.
The rollout shows the limits of current infrastructure. Payment volumes remain modest, and security debates continue across the industry.
Base said it plans to expand MCP with additional plugins and improved prompt flows. The company also aims to deepen integration with AI tools that users already rely on.
The result points to a hybrid model. AI agents handle complexity, while users retain final authority over assets.
