Memento is a shared memory system for AI agents that stores knowledge as Markdown files in a Git repository, with derived indexes for search. It uses a fine-tuned local model to route natural-language requests into bounded read operations, while writes follow a proposal-review-apply workflow to ensure safety and consistency. The project is notable for its novel combination of Git-based versioning, MCP protocol integration, and model-assisted but deterministic operations.

Target audience: AI agent developers, backend engineers building multi-agent systems
