MemRosetta adds persistent memory to Claude Code with one command setup

Persistent memory for Claude Code sessions

MemRosetta is a tool that adds persistent, cross-session memory to Claude Code, addressing the issue where each session starts from scratch. The setup requires one command and stores memories locally in a SQLite file.

Installation and setup

To install and initialize MemRosetta for Claude Code:

npm install -g u/memrosetta/cli && memrosetta init --claude-code

This command sets up three components:

• MCP server with 6 memory tools
• Stop Hook that automatically captures information when sessions end
• CLAUDE.md instructions that tell Claude when to store information

How it works in practice

During Session 1, if you tell Claude: "Let's use PostgreSQL. Auth is OAuth2 with PKCE." - Claude stores these decisions.

In Session 2 (the next day), when you ask: "What did we decide about the database?" - Claude retrieves "PostgreSQL" from the previous session's memory.

Technical details

• Everything is stored locally in one SQLite file
• If you also use Cursor, both tools can share the same database
