What is ModusBrain?

ModusBrain is Genthropic's flagship memory and skills framework for AI agents.

It serves as the cognitive layer and central repository for an agent's knowledge, long-term memory, and integrations. ModusBrain installs over 60 default skills and custom skill packs, connects your agent to vector search engines (such as Supabase pgvector), exposes Model Context Protocol (MCP) servers, and synchronizes automatically with Git repositories.
