Vlk MemAct MCP Server

Vlk² gives AI agents a sense of time: what's happening now (PRESENT), what's already been tried (PAST), and what should guide future decisions (FUTURE). It runs as a single binary over MCP, backed by SQLite, and manages these temporal transitions autonomously.

People who need memory tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
