What is a Broker Trading API?

A programmatic REST or WebSocket interface allowing developers and quantitative trading programs to place orders, stream market ticks, and query portfolio positions directly without using the web or mobile UI.

What is Model Context Protocol (MCP)?

Spec

An open standard developed by Anthropic that allows AI agents (like Claude and custom assistants) to discover tools, query live data, and safely execute structured actions via standardized JSON schemas.
