aescaffre/pixinsight-mcp ? reverse-engineered prompt

Build me an MCP server for PixInsight that lets me run deep sky astrophotography processing with an AI assistant. I want to give it a simple JSON config with my calibrated stacked frames and a few notes about the target, like whether I want to push faint detail, keep the stars tight, or make the colors more vivid, and then have it handle the whole workflow in a smart way.

It should do the basic processing first, like alignment, background cleanup, noise reduction, sharpening, color calibration, and stretching, then hand control to Claude for the creative decisions. I want it to generate a few candidate versions, compare them, avoid ugly artifacts like burnt cores or ringing, and save a finished image plus a preview. If it helps, look up the current PixInsight and MCP docs online as you go. Make it feel like a practical tool I can actually use on real targets, not a demo.
