MCP Interaction Workflow: A Step-by-Step Example

At this stage, you already know the core MCP building blocks and its workflow patterns Here are some key points we learned so far:

• MCP is a protocol for structured communication between an MCP host (for example, a chatbot application) and one or more MCP servers (for example, tools, resources, or prompt managers).
• Both client and server expose their capabilities through a standardized JSON-RPC 2.0 interface.
• Messages continue using JSON-RPC 2.0 envelopes during the exchange to maintain a consistent structure and support concurrency.
• The transport layer can be either HTTP (remote) or STDIO (local) depending on the use case.
• Message exchange can be requests, responses, or notifications.
