Tool Protocol Client

Software componentTools & IntegrationOrchestration & Toolsarc:ToolProtocolClient

A client that connects an agent to remote standard tool-protocol servers, discovers their tools at runtime and makes them invocable alongside local tools.

Responsibility. Dynamically loads and invokes tools hosted on remote tool-protocol servers.

Also known as: MCP client, Dynamic remote tool loader
