MCP Memory Server

A Model Context Protocol (MCP) server for Claude Desktop that provides structured memory management across chat sessions, specifically designed for project-based work.

Project-Focused Memory Management

This MCP server is specifically designed to help Claude maintain context and knowledge within project directories when used with Claude Desktop. It allows Claude to:

• Create a memory store within your project directory

• Save important information discovered during conversations

• Retrieve relevant memories in future sessions

• Build a comprehensive knowledge base about your project over time

This approach is ideal for long-term projects where maintaining context between sessions is crucial, such as software development, research, writing, or any collaborative work with Claude.
