Optuna MCP server

This is a small helper program that connects your AI assistant to Optuna, a free tool for finding the best settings for a task. It is handy for anyone who wants to try many combinations of values and see which one works best, without writing code. You just chat with your AI, and it runs the experiments for you.

What this MCP server does

You ask your AI to start an optimization study, for example to find the best settings for a recipe or a video encoder. The AI uses this helper to create the study in Optuna. Then the AI suggests a set of values to try, you or the AI measure the result, and the AI records it. This repeats, and Optuna learns from each round to suggest better values. At the end, you can ask for charts or a dashboard to see what worked best.

What you can do with it

• Start a new optimization study with a name and a goal (minimize or maximize)
• Ask for suggested values to try next
• Report the result of each try
• See the best result so far
• Get a chart of how the results improved over time
• See which settings matter most
• Open a web dashboard to explore the results

Try asking your AI

• “Create an Optuna study called Find-Best-Cookie for maximizing taste.”
• “Suggest two values for sugar and butter between 0 and 200 grams.”
• “Report the taste score 8.5 for that trial.”
• “Show me the optimization history plot.”

What it gives back to you

You get answers in the chat: lists of suggested values, the best result found so far, and tables of past tries. When you ask for a chart, it appears as an image right in the conversation. If you launch the dashboard, you get a link to a web page where you can click around and see the same charts.

Who it's for

Anyone who wants to find the best settings for something by trying many combinations, like data scientists, engineers, or curious tinkerers.
