MCP provides interoperable discovery and invocation across AI hosts and capability servers while preserving explicit control boundaries.
Before working through the formal derivations, connect the vocabulary to one small, concrete example. The goal is not to memorize definitions in isolation. It is to understand what each idea represents, which assumptions make it valid, and how the pieces relate to one another.
Ideas to understand
- Host, client, server, and session architecture
- Initialization and capability negotiation
- Tools, resources, prompts, requests, responses, and notifications

Make the idea concrete
Explain the core model and vocabulary for Model Context Protocol using a concrete example, measurements, and a short design explanation.
Try this
- Define “Host, client, server, and session architecture” in your own words, then annotate one concrete Model Context Protocol (MCP) input and output.
- Construct one valid case and one counterexample for “Initialization and capability negotiation”; explain which assumption separates them.
- Predict how “Tools, resources, prompts, requests, responses, and notifications” will change one visible playground result, then test and record the before/after values.
Evidence of understanding
- You can explain the example without relying on jargon.
- You can name the assumptions and identify what would invalidate them.
- You can connect the example to at least one real ML use case.
What part of the Model Context Protocol (MCP) mental model still feels least intuitive, and what example would help clarify it?
