From MCP to Money: How We Gave Claude a Wallet

Anthropic's Model Context Protocol (MCP) is one of the most important pieces of AI infrastructure released in the past two years. It standardizes how AI models connect to external tools.

What MCP Enables

Before MCP, connecting an AI model to external tools required custom integration code. MCP standardizes this as a JSON schema with a name, description, and parameter specification.

The Wallet Tool

We defined a rosud_send_payment MCP tool that exposes Rosud's payment API to any MCP-compatible model.

The Implementation

The MCP server implementation connects to Rosud's API. When Claude calls the tool, results return immediately.

What Claude Can Do With a Wallet

With this tool, Claude can make autonomous payment decisions. Real examples: research agents paying for data, code generation agents commissioning specialists.

Security Considerations

API keys should be scoped with spending limits. Approval flows require human confirmation for payments above thresholds.
