Covalence – Cross-Client Memory for Claude, Cursor, and MCP (macOS)

Show HN: Covalence – Cross-Client Memory for Claude, Cursor, and MCP (macOS)

Operating in show hn launch, Covalence – Cross-Client Memory for Claude, Cursor, and MCP (macOS) operates.

Profile

I use Claude Desktop, Claude Code, and Cursor daily. They all have memory now, but none of them share it. Something I explained in Claude Desktop doesn't exist when I open Cursor. I got tired of re-explaining my stack, my preferences, and my project context every time I switched tools.Most solutions I found required Docker, external databases, or cloud accounts - overkill for what's essentially a personal context store. So I built Covalence: a Mac app that bundles an MCP server and a local vector database into a single download. Any MCP client connects to it. Store a memory in Claude, retrieve it from Cursor. Same database, zero config.The stack: SQLite + sqlite-vec, nomic-embed-text-v1.5 ru

Its activity falls under show hn launch; the profile below is assembled from public directory data.
