What is MCP? How do LLMs call via MCP? How does the MCP Authorisation work? and other aspects
MCP looks like the Golden Key to unlock the full potential of LLMs. From Google to Microsoft (MCP on Windows 11) and everywhere in between

Model Context Protocol (MCP) is a groundbreaking framework that facilitates the integration of large language models (LLMs) with API calls, presenting a pivotal shift towards standardization in how these technologies can interact. The article initially explains MCP’s function and effectiveness, illustrating it with practical examples, including its application in a simple calculator server. It emphasizes the flexibility of MCP in accommodating various tools while ensuring that the design remains user-friendly. Additionally, the article details the authentication flow in MCP, particularly its implementation within the financial sector using Zerodha Kite as an illustrative example, ultimately asserting that MCP stands as a potentially universal standard for automation and API interaction in AI.
