Hermes Agent: what it actually is in 2026 (not the LLM)

I got this wrong in an earlier draft. Let me correct the record.

Hermes Agent (NousResearch/hermes-agent) is a real, actively-maintained terminal agent CLI — 210K GitHub stars, last pushed 2026-07-07. It is completely separate from NousResearch/Hermes-Function-Calling (the Python LLM demo notebook with 1,416 stars). Same GitHub org, completely different projects.

What Hermes Agent is

NousResearch/hermes-agent is a general-purpose terminal agent with:

• MCP integration — connect any MCP server for extended capabilities
• Skills system — /skills command, agentskills.io compatibility
• Memory/learning loop — Honcho dialectic user modeling, FTS5 session search
• Messaging channels — Telegram, Discord, Slack, WhatsApp, Signal, Email
• Windows support — PowerShell installer
• hermes-cli-mcp — npm package (v1.0.1, 2026-05-22) that wraps the Hermes CLI binary as an MCP server, confirming it ships a real standalone binary

It is general-purpose first (assistant, memory, messaging) with coding agent capabilities alongside — not exclusively a coding agent like Claude Code.

Hermes Studio is separate

EKKOLearnAI/hermes-studio is a desktop app / web dashboard / Docker console for managing Hermes Agent. It supports "dedicated proxy routes for Codex and Claude Code integrations" — meaning it can launch Claude Code or Codex as coding agents from inside its UI. Hermes Studio is the management plane; Hermes Agent is the actual agent runtime.

What Hermes Agent is NOT

It is not NousResearch/Hermes-Function-Calling — that repo is a Python Jupyter-notebook demo for structured function calling using Nous Hermes LLMs (stock prices, financial data). 1,416 stars, last commit 2025-12-22. A completely different project with the same organisation name and similar branding.

The confusion is understandable. Both live under NousResearch. Neither Google searches nor AI roundups consistently disambiguate them.

Comparison to Claude Code and OpenCode

	Hermes Agent	Claude Code	OpenCode
Type	General-purpose agent + messaging	Coding agent CLI	Coding agent CLI
Stars	210K	137K	183K
MCP	✅	✅ native	✅ native
Skills	✅ agentskills.io	✅ npx skills	✅ npx skills
Windows	✅ PowerShell	✅ npm	✅ npm binary
Coding focus	General (coding is one capability)	Dedicated	Dedicated
Messaging	✅ Telegram/Discord/Slack/WhatsApp	❌	❌
Memory	✅ Honcho + FTS5	✅ auto-memory	✅
Free tier	✅ BYOK	✅ with API key	✅ free providers

Hermes Agent is genuinely comparable to Claude Code and OpenCode as a terminal agent — it just covers a wider surface (messaging + assistant + coding) rather than being coding-first.
