Create an Info Icon with Codex CLI

By the Axialis Engineering team ·

You want an AI agent to draw a real, pixel-aligned vector icon instead of handing back loose SVG markup you still have to clean up. This walkthrough drives IconVectors entirely from Codex CLI over MCP to produce a finished 32x32 "info" icon — a blue circle with a centered white "i" — exported straight to SVG from one prompt.

It works on Windows, macOS, and Linux as long as your Codex MCP setup is already running. If it isn't, set that up first with Using IconVectors with Codex CLI.

Three processes, two hops. Codex CLI starts the MCP sidecar and talks to it over stdio. The sidecar publishes the 166 tools and forwards each call over the loopback port to the running editor, and only the IconVectors window that owns that port answers. Seeing the tool list means the sidecar started; app_ping is what proves the editor is reachable.

Exact prompt

Using IconVectors MCP commands, create a new 32x32 document named "info icon", draw a blue circle
in the center, use a color from the "Axialis Colors" palette, draw a large info "i" white letter
using 2px round corners, center vertically and horizontally the "info" group, and export it as SVG.

What this prompt asks Codex to do

Watch the icon get built in real time

Codex CLI runs on the left and IconVectors on the right. As the prompt executes you can watch the 32x32 document open, the blue circle and white "i" appear as editable vector shapes, and the SVG export complete — no manual drawing.
