Longhand

Longhand is an open-source Model Context Protocol (MCP) server and CLI tool designed for persistent, local memory management with Claude Code. It captures, stores, and indexes all code sessions, tool calls, and edits locally using SQLite, making your code history instantly searchable and recallable through natural language queries — all without using any API calls. This tool is useful for developers and teams who use Claude Code and want comprehensive, fine-grained recall of past sessions for debugging, knowledge management, and workflow optimization.
