**Context as code. Memory as asset.**

n2n-memory is an open-source, local-first Model Context Protocol (MCP) memory server for AI coding assistants. It prevents cross-project memory pollution by storing durable project knowledge in `.mcp/memory.json` and active task context in `.mcp/context.json` inside each repository.

💡 What is n2n-memory?

n2n-memory gives AI coding tools a project-local knowledge graph they can read and update through MCP. Memory and context are stored inside each repository under `.mcp/`, keeping them isolated, Git-friendly, and reviewable.

• Restore project context at the start of an AI coding session.
• Preserve architecture decisions, implementation notes, and known pitfalls.
• Share durable project memory with teammates through Git.
• Keep memory isolated per repository when working across many projects.

🚀 Quick start

1. Configure your MCP client
