What Is MCP and Why Does It Matter?
Model Context Protocol (MCP) is an open standard that allows AI systems to discover and use external tools through a structured interface.
Traditionally, developers integrate APIs by reading documentation, building requests, validating parameters, and handling responses manually. AI agents face the same challenge. Before they can retrieve data, they must understand which endpoint to call, what parameters are required, and how responses are structured.
MCP solves this problem by making APIs self-describing.
Instead of exposing only URLs, an MCP server publishes available tools, parameters, authentication requirements, and response schemas in a machine-readable format. AI agents can discover capabilities automatically, validate requests before execution, and retrieve structured data without custom integration logic.
For financial applications, this creates a more reliable way for AI systems to interact with market data, exchange rates, indexes, and historical datasets.
