This guide clarifies the Model Context Protocol (MCP) architecture to help teams decouple AI models from the specific implementations of external tools.
Provide an MCP overview for your project by outlining the Host, Client, and Server roles and the JSON-RPC flow.

The Model Context Protocol (MCP) is an architecture that decouples AI models from external tool implementations. It works by defining Host, Client, and Server roles that manage tool integration, security policies, and user interactions to enable reliable AI tool orchestration.
To design an MCP application, you outline the Host, Client, and Server roles and establish the JSON-RPC 2.0 workflow. This involves specifying functional requirements for tool discovery, execution, standardized results, and selecting appropriate transport mechanisms like stdio or SSE.
MCP supports two primary transport mechanisms for tool communication: stdio for local tools and SSE (Server-Sent Events) for remote services. These options enable reliable JSON-RPC 2.0 messaging between the Host, Client, and Server components during tool execution.
In MCP tool integration, the Host, Client, and Server each have distinct roles and responsibilities. The architecture clarifies these components to manage tool discovery, handle security policies, execute external tools, and return standardized results back to the AI model.
Yes, the Model Context Protocol uses JSON-RPC 2.0 for messaging. This standardized messaging protocol enables reliable communication and defines the end-to-end workflow for tool discovery, execution, and returning standardized results across the Host, Client, and Server architecture.
You should use stdio for local tools and SSE for remote services when configuring MCP transport. Choosing the correct mechanism ensures reliable JSON-RPC 2.0 communication and proper tool execution depending on whether the external tool implementation is local or remote.
