Covenant Guard MCP Server

Covenant sits below agent applications and above the host operating system. It owns the state, authority, and accountability concerns that recur across agent frameworks - scoped capabilities, durable memory, runtime isolation, append-only audit, and commit-scoped provenance - so individual frameworks can stop reinventing them.

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