MCP and AI image guides, in reading order
Six guides that take you from “what is MCP” to a compressed image committed to a repository. Reference documentation tells you what the parameters are. These tell you which decision you are actually making, why the obvious approach costs more than it should, and what to do when the first result is not the one you wanted.
Learning the protocol itself?
These are applied guides, not a course. If you want to learn MCP properly from the ground up, the specification and its introduction are the authority, and Anthropic, Hugging Face and Microsoft all publish full curricula on building servers from scratch. What follows is the part none of them cover: using MCP for image work, with the costs, formats and failure modes attached.
Start here
The concepts everything else assumes.What is MCP?
The Model Context Protocol explained without the marketing: host, client, server and transport, the three primitives a server exposes, and how it differs from both an API and RAG.
MCP vs REST API
One question decides it — who chooses what to call, the model or your code? Includes the same task done both ways, and the honest case for skipping MCP entirely.
Building
Turning capability into a pipeline that behaves.Add image generation to an AI agent
Six decisions, the tool schema to paste into any framework, a worked pipeline that passes URLs rather than bytes, and the five mistakes that cost real money.
How to write AI image prompts
The six components of a prompt that works, twelve examples you can copy, whether to use commas or sentences, and the parameters that quietly do nothing.
Shipping
The decisions that happen after the image exists.WebP vs AVIF vs PNG vs JPEG
Two questions settle almost every case. With the actual size numbers, the fallback markup, and why SVG is not on the same list and cannot be converted into.
Bring your own OpenRouter key
What BYOK changes and what it does not, the break-even price per image, and the five reasons a connected key looks like it is doing nothing.
Before you start
Where should I start if I am new to MCP?
Guide 01, then 02. Between them they cover what the protocol is and when it is the right tool — which is enough to make every other decision on this site make sense. If you already run MCP servers, skip to 03.
Are these a substitute for the official MCP course?
No, and they are not trying to be. Anthropic, Hugging Face and Microsoft all publish full MCP curricula that teach you to build servers from scratch, and the specification itself is the authority on the protocol. These guides cover the narrower thing none of those do: using MCP for image work, with the costs, the formats and the failure modes attached.
How long does the whole set take?
About 52 minutes end to end, though they are written to stand alone. Most people read 01 and 03 and come back for the others when a specific decision comes up.
Do I need an account to follow along?
Only for the parts that make real calls. The concepts, comparisons and format decisions need nothing. A free account is 30 credits a month with no card if you want to run the examples.
