MCP Client

The component inside an AI host application that maintains a connection to an MCP server.

Definition

Each client holds a one-to-one connection with a server, discovers its capabilities and relays tool calls and results between the model and the server. The host (such as Claude Desktop, Claude Code or an IDE) manages clients, user consent and security.

Exam tip

In MCP, the host application creates one client per server connection.
