Stemem MCP

Stemem is a local-first, zero-outbound MCP stdio server that provides a dynamic personality runtime for AI agents. It persists agent persona state in local JSON files, ensuring personality survives session compaction and restarts. It exposes 9 tools to manage traits, emotions, and behavioral drives, allowing agents to maintain consistent, evolving personalities across interactions without relying on static system prompts.
