Physbound

PhysBound is an open-source MCP (Model Context Protocol) server that acts as a rigorous physics validation and linting tool for RF engineering, telecommunications, and signal processing workflows. It exposes tools to compute and verify radio link budgets, Shannon-Hartley channel capacity, thermal noise floors, radar range equations, and validates all calculations against hard physical limits, detecting and flagging hallucinated or physically impossible claims from AI assistants. PhysBound integrates seamlessly with any MCP-compatible AI-assisted coding tool (such as Claude, Cursor, Windsurf) and is ideal for engineers, educators, and organizations seeking trustworthy, physics-constrained results in automated or AI-driven workflows.
