Key Insights:
- Coinbase’s Payments MCP enables AI models to perform wallet tasks using simple, natural language.
- Claude and Gemini models can now handle fiat on-ramp and stablecoin transactions securely.
- Developers can locally deploy and customize Payments MCP to maintain privacy and control.
- The partnership with the x402 Foundation supports open AI standards in blockchain payment systems.
Coinbase has introduced a new system called “Payments MCP,” which enables AI models to handle crypto wallet tasks and payments. This tool supports large language models, such as Claude and Gemini, providing them with access to wallet operations and stablecoin transactions through simple natural language.
New Feature Designed for AI and Crypto Integration
The Coinbase Developer Platform developed the Payments MCP system to simplify crypto payments using artificial intelligence. It enables AI systems to perform wallet actions, assist users in buying crypto with fiat money, and facilitate the sending of stablecoin payments.
Coinbase confirmed that Payments MCP can work with locally hosted AI models and can be customized by developers. The system connects with LLMs, so users can ask questions and complete tasks using simple instructions instead of technical commands.

The tool is part of Coinbase’s broader goal to expand the crypto economy by making it easier to access through AI. Coinbase stated that this tool is compatible with numerous AI models, allowing developers and users to avoid relying on a single provider.
Partnership with x402 Foundation for Standards
Payments MCP was launched in line with the x402 Foundation, which Coinbase and Cloudflare started. This group supports the development of open standards for AI and cryptocurrency payments. It also ensures that AI tools adhere to safe and agreed-upon rules when interacting with crypto systems.
The foundation aims to establish a unified approach for AI models to access payment systems. This includes supporting wallet operations and verifying actions for safety. The goal is to build a secure and open way for models to connect with blockchain networks.
A Coinbase spokesperson said, “The system is designed to allow large language models to take action, not just provide information.”
Custom Use and Local Deployment for Developers
The tool supports local use, allowing developers to run the system on their own servers. This is useful for companies that want more control over data and privacy. It also enables businesses to develop tools without sharing private information with external platforms.
Developers can also modify the system’s functionality to meet their specific needs. This flexibility could help companies create custom tools for users, using natural language to send payments, manage funds, or complete wallet actions.
