Model Context Protocol (MCP) client is a component that connects a user’s AI application or interface to the MCP server. It is a lightweight SDK (Software Development Kit) or shim, residing within the host environment like the agentic application or LLM-powered system. It acts as a runtime coordinator to allow AI systems to invoke tools, interact with models, and execute workflows securely and modularly through the MCP server. 

Why is MCP client important?

A MCP client abstracts the complexity of the backend and gives developers an easy way to interact with agents or tools via MCP.
