armguard-mcp

A safety-first Model Context Protocol server for ROS 2 manipulators that enforces server-side safety envelopes including joint limits, workspace boxes, force thresholds, and rate limits. It requires human approval via MCP elicitation for unsafe motions, provides a software e-stop, and maintains an audit log of all actions to prevent unintended robot movement caused by LLM errors or prompt injections.
