hermes-agent vs pctx

hermes-agent: Hermes Agent is a self-improving AI agent from Nous Research with a built-in learning loop: it creates skills after complex tasks, improves them during use, searches its own past sessions and builds a model of the user over time. It works with any model provider, talks through a terminal UI or Telegram, Discord, Slack, WhatsApp and Signal, and runs on local, Docker, SSH or serverless backends.; pctx: pctx sits between AI agents and MCP servers, aggregating multiple upstream MCP servers, handling authentication, and exposing tools through a unified Code Mode interface. It replaces sequential tool calling with code execution, resulting in significant token reduction. It supports multiple installation methods and provides Python SDK for agent development.
