Doberman is an open-source, runtime security layer for AI coding agents. It sits between the agent and its tools and gives every action a PASS, AUTH or BLOCK verdict before it runs. A deterministic core catches known dangerous behavior, while an adaptive layer learns what’s normal for you and raises risk when something looks off. It fails closed and learning is raise-only. Works with Claude Code, Codex, OpenClaw and MCP clients like Cursor.
