THOR MCP Server

Most memory tools can only remind your assistant. THOR can refuse. Give it a note with a proof attached - a small check it can run right now, like "this file still contains that line." From then on the note stops being advice. THOR refuses the matching edit or command before it runs. Not a suggestion your assistant is free to skip. A hard stop.

People who work with agent memory, coding assistant and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
