harnessrouter vs gpu-mcp-server

harnessrouter: HarnessRouter provides a unified infrastructure layer that transforms various agent harnesses (like Codex and Claude Code) into plug-and-play backends, enabling products to run tasks, retrieve results, and switch between harnesses via a single API. It implements the Unified Harness Protocol (UHP) and offers an OpenAI Responses-compatible API for managing persistent sessions, streaming progress, files, and task lifecycle without complex harness engineering.; gpu-mcp-server: gpu-mcp-server is an MCP-compatible server that exposes real-time NVIDIA GPU metrics as tools for AI agents. It allows agents like Claude, Goose, and Cursor to query utilization, memory, temperature, and power data without external monitoring systems.
