Yggdrasil

Overview

Yggdrasil is a Model Context Protocol server that provides shared, durable memory for AI coding agents. It operates local-first with zero dependencies, letting any MCP-compatible AI assistant access its memory tools directly during conversations and agent runs.

The server runs locally as a Python package installed via uvx yggdrasil-memory and communicates over stdio. It requires an API Key for authentication. The current release is v0.15.0, published under the AGPL-3.0 license with source code available at VonderVuflya/yggdrasil on GitHub.

Yggdrasil is categorized as Development and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing on mcp.site to verify ownership and keep information accurate.
