ShadowGraph MCP server

ShadowGraph is a memory tool for your AI that keeps track of decisions, not just conversations. It saves what was chosen, what was turned down, the reason, and the moment a choice should be looked at again. It is handy if you use an AI assistant on a long project and want it to remember why things were done a certain way.

What this MCP server does

You ask your AI something like why a certain tool was picked for a project. The AI uses this helper to look inside your local ShadowGraph store. The store holds the decision, the alternatives that were rejected, the reasons, and any conditions that would make the choice worth revisiting. The AI then tells you what it found, or records a new decision for you. Everything stays on your machine, and nothing is sent to a cloud service.

What you can do with it

• Record a decision with the options you rejected and the reason
• Save a fact, like the deployment being single-user, that can trigger a rethink
• Ask what decisions should be reviewed again now
• Look up why something was decided in the past
• Note a failed attempt so the same mistake is not repeated
• Store preferences, goals and notes for a project
• Mark a review signal as seen so it stops piling up

What it gives back to you

You get back plain answers in the chat, like a short list of decisions that need a second look, or the reason a choice was made. When you record something, the AI confirms it was saved. When you ask a question, you get the matching decisions, facts or notes with their reasons. Nothing is hidden or summarized away without telling you.
