Hermes

Your AI's messenger.

Hermes bridges Claude and your terminal — watches responses in real time, runs bash commands with your approval, and sends results straight back. No copy-paste. Just conversation.

Four steps.
One seamless loop.

01
👀
Hermes Watches

Runs in your terminal and quietly monitors your Claude.ai tab in Safari or Brave. No configuration. No plugins.

02
Claude Responds

The moment Claude finishes a message, Hermes detects it, extracts every bash command, and surfaces them instantly.

03
You Execute

Review each command one by one, skip what you don't need, or enable auto-mode with a 3-second abort window.

04
📤
Loop Closes

Output is formatted and injected back into Claude automatically. Claude sees the results and continues — no copy-paste.

Hermes detects your browser — finds a Claude.ai tab in Safari automatically, no config needed.

Built for developers
who think differently.

Zero Config Detection

Hermes finds your Claude tab automatically. Point it at Safari or Brave — no browser extensions, no API keys, no setup.

Command-by-Command Control

Every extracted command waits for your keystroke. Execute, skip, go back, or grab to clipboard. You decide what runs.

Auto-Execute Mode

Add #hermes to any Claude response and commands run automatically with a 3-second abort window. Safe, fast, intentional.

Result Injection

Command output is formatted and sent straight back into your Claude conversation. Claude reads results and continues iterating.

History & Grab

Browse every command executed in the session. Grab any output to clipboard. Full audit trail without leaving the terminal.

Pure Python

Zero dependencies beyond Python's standard library. No npm, no virtualenv, no pip install. Clone and run — it just works.

Claude reasons.
Hermes acts.

Stop copy-pasting commands. Let Hermes close the loop between Claude's thinking and your terminal. Open source, free forever.
