Base has launched Base MCP, a new infrastructure tool designed to connect AI agents directly with crypto wallets and on-chain applications through conversational chat interfaces.
The launch represents another major step in the growing convergence between artificial intelligence and blockchain payments. Base MCP allows users to perform crypto-related actions through AI assistants while still maintaining direct approval control over transactions.
According to Base, the tool supports:
- Token transfers
- Wallet balance checks
- Token swaps
- Transaction history reviews
- x402 payment flows
- Interactions with supported DeFi apps
Base MCP is compatible with AI platforms that support the Model Context Protocol, including OpenAI ChatGPT, Anthropic Claude, Codex, and Cursor.
A key feature of the system is that AI agents do not directly control user private keys. Instead, when an AI proposes a transaction, the connected Base Account generates a separate approval window where the user must manually review and confirm the transaction before anything is executed on-chain.
Base said each confirmation screen displays expected asset changes and transaction details to help reduce accidental approvals.
The system launches with integrations across several Base ecosystem applications, including:
- Uniswap
- Morpho
- Moonwell
- Aerodrome
- Virtuals
- Avantis
These integrations allow AI assistants to help users interact with lending markets, liquidity pools, swaps, token launches, and perpetual futures platforms through natural language conversations.
The rollout also deepens Coinbase’s broader push into AI-native payment infrastructure through the x402 protocol. x402 is designed for machine-to-machine payments using stablecoins such as USDC on Base.
Related ecosystem developments include:
- AI marketplaces like Agentic.market enabling autonomous service purchases using USDC
- Integration of x402 payments into cloud infrastructure services
- Expansion of stablecoin micropayments for APIs and automated software agents
At the same time, the launch arrives amid growing security concerns surrounding AI-driven crypto tools. Researchers and security firms have warned that AI agents should still be treated cautiously because malicious prompts, compromised plugins, or fake interfaces could potentially manipulate transaction approvals.
Recent malware campaigns targeting crypto and AI developers have also increased scrutiny around wallet security, API access, and credential management across AI-integrated systems.
Base emphasized that its MCP server never stores or accesses private keys and that all blockchain actions still require explicit user authorization before execution.
