MCP server

An MCP server is a service that exposes an application's functions as tools an AI assistant can call, using the open Model Context Protocol.

In practice

The Model Context Protocol is a shared standard, so any assistant that speaks it can use any server that speaks it. Claude, ChatGPT, Cursor and other clients connect to an MCP server and gain the ability to read data and take actions in that application.

For payments, this means an AI agent can do what the API allows, within the access it has been given: onboard a customer, price a payout, send it and check its status.

Stables hosts an MCP server at mcp.stables.money. You connect by signing in with your Stables account or by using a sandbox API key. Every connection appears in your dashboard and can be revoked, and every payment an agent makes still runs through the same transfers and compliance checks as any other.
