moss-hermes

MOSS integration for Nous Research Hermes agents.

Overview

Cryptographic signing for Hermes AI agent actions using ML-DSA-44 (NIST FIPS 204) post-quantum signatures.

Installation

pip install moss-hermes

Quick Start

from moss_hermes import sign_tool_call

signed = sign_tool_call(
    tool_name="send_email",
    tool_input={"to": "user@example.com", "body": "Hello"},
    tool_output={"status": "sent"},
    agent_id="hermes-assistant"
)
