Software
AI platforms and their tools — the APIs, agents, caching, tool use and MCP: how to make a model do work for you, step by step, with every example run.
Last machine check against the sources:
- 1What Prompt Caching Is
Turn on prompt caching by adding two lines to a request, and prove from the response's own numbers that it worked.
- 2What Tool Use Is
Define one tool, send it with a question, and see the model ask for it instead of guessing — in a file you wrote and ran yourself.
- 3What MCP Is
Write an MCP server that offers one tool, and send it a message by hand to see exactly what it answers.
- 4What Structured Output Is
Write a JSON Schema for the data you need, and send it with a request so the reply follows it.
