Artifacts

This is a persistence layer for AI conversations that lets you save decisions, plans, and notes from any chat session and pull them back later, even from different clients. It runs as a remote server over SSE transport at artifacts.mctx.ai, so you're not locked into a single MCP client. The core use case is when you make a decision or capture important context in one conversation and need to reference it hours or days later without digging through chat history. Think of it as shared memory across your AI sessions. You'd reach for this when you're using AI for ongoing projects where decisions and context need to stick around between conversations, like tracking architecture choices or keeping running notes on a codebase.
