Intro to Model Context Protocol (MCP)

Scrimba offers a compact implementation introduction, with a listed workload of about an hour. The focus is the basic server and client relationship: define capabilities, expose them through MCP, and connect an application that can use them. This short scope makes it useful for testing whether the protocol belongs in a JavaScript project.

What you will learn

• Describe how MCP connects a model application with external capabilities.
• Define tools and resources on a simple server.
• Create a client connection and inspect the exchange.

Who this suits

Developers who already understand basic JavaScript and prefer a short practical introduction.

Before you enroll

A solid foundation in JavaScript is an explicit prerequisite. Allow additional time to configure your environment and rebuild the example independently.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Tool subscriptions, model API usage and cloud services may cost extra.

Put it into practice

Replace one example capability with a deterministic unit converter. Compare a valid request with an unsupported unit and explain the server’s response.
