cdeust/Cortex

What it does

Cortex is a persistent memory system designed specifically for Claude that implements neuroscience-based memory mechanisms. It provides Claude with the ability to maintain and retrieve contextual information across conversations using principles grounded in 41 cited neuroscience papers. The system uses PostgreSQL with pgvector for efficient storage and retrieval, offering 33 specialized MCP tools and 7 lifecycle hooks for memory management.

How to set up

Install via the Claude plugin marketplace using the command: claude plugin marketplace add cdeust/Cortex. Configure a PostgreSQL database with pgvector extension. Initialize the memory system through the provided MCP tools and lifecycle hooks to enable persistent storage and retrieval mechanisms.
