microcharts MCP server

Lets your AI pick, set up and draw tiny word-sized charts as finished SVG pictures.

This is a small helper that lets your AI make little charts, the kind that fit inside a sentence, like a sparkline or a small bar. You ask a question in plain words, and the AI finds the right chart and draws it for you. It is handy for anyone who wants a quick visual in a chat or a document without opening a spreadsheet.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you in text. An MCP server is a small helper program that gives your AI a new skill or a connection to another tool. This helper connects your AI to microcharts, a chart library, so the AI can look up the right chart and draw it. You just ask, and the AI uses this helper behind the scenes to hand you a finished picture.

What this MCP server does

You ask your AI something like whether a number is trending up. The AI calls this helper, which looks through a list of small chart types and picks the best match. Then it gets the exact setup for that chart and draws it as a finished SVG picture, along with a short written description of what the chart shows. You get the picture and the description right in your chat. It all runs on your own computer, so nothing is sent anywhere.

Flow diagram: you ask your AI “Is this number trending up? 132, 148, 141, 165, 182”, the microcharts MCP server works in steps: picks the chart, then gets it ready, then draws the picture, and you get back A small chart and a short note.

“Is this number trending up or down? Here are the values: 132, 148, 141, 165, 159, 182”
“Draw a bullet chart with value 72 and target 80”
“What small chart should I use to compare a few categories?”

What it gives back to you

You get back a finished SVG picture, which is a kind of image file that shows up right in the chat. Along with it comes a short sentence describing the chart, like the trend and the range of values. You also get the picture's size. If your numbers are missing or the wrong shape, you get a clear message telling you what is needed instead of an error.
