SubVault is an MCP server that gives Claude, Cursor, and Copilot permanent memory across every session.
SubVault solves a real, daily frustration: every AI session starting at zero. The two-word interface is genuinely simple, the structured extraction beats transcript dumps, and being free during early access removes all friction to try it. Best for developers and researchers who use Claude or Cursor heavily; less useful if your team works primarily in ChatGPT or other non-MCP tools.
Two commands do everything: "vault this" saves session context, "remember [topic]" retrieves it across Claude, Cursor, and VS Code Copilot
Extracts structured facts — decisions with reasoning, people and roles, action items, project patterns — not raw chat logs
4-axis scoring ranks items by authority, recency, relevance to your query, and salience before injecting context
Dedup and contradiction detection prevent stale or duplicate items from cluttering your AI's memory
30-second setup: one curl command auto-configures Claude Desktop, Cursor, and VS Code
