hermes-agent vs mcp-js

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.; mcp-js: mcp-v8 provides a secure and efficient JavaScript/TypeScript runtime for AI agents, allowing them to execute code within a sandboxed V8 isolate. It simplifies agent development by offering a single, powerful `run_js` tool instead of multiple narrow utilities, supporting durable state and policy-gated capabilities.
