mordred-hermes

Privacy-preserving plugins for the Hermes agent: at-rest secret encryption, hardware-backed keys, Tor/VPN routing, local-LLM policy enforcement, and end-to-end encryption for Slack and Discord gateway messages.

Status: active alpha — current release 0.1.0a15.

New here? Follow the Quickstart for the shortest path from an existing Hermes install to encrypted secrets.

The plugins

The package exposes six hermes_agent.plugins entry points:

Requirements

• Python 3.11 or newer; CI currently tests 3.11–3.13.
• hermes-agent>=0.13.0. The host form hermes mordred ... additionally requires Hermes 0.19.0 or newer; the standalone hermes-mordred command works across the supported range.
• macOS or Linux. macOS can fall back from Secure Enclave to a software P-256 key in the login Keychain. Linux requires TPM 2.0 and fails closed when its helper is unavailable.

Install (users, from PyPI)

Start with an installed Hermes Agent, then run the Mordred installer:

curl -fsSL https://raw.githubusercontent.com/InternetMaximalism/mordred-hermes/main/scripts/install.sh | bash

The script follows Hermes's own install layout: it resolves the environment behind the hermes on your PATH, checks the Hermes version, selects the macOS or Linux dependencies, installs the PyPI package there, and writes a hermes-mordred launcher next to hermes that scrubs PYTHONPATH / PYTHONHOME exactly as Hermes's own launcher does. It does not configure Mordred or create keys.

To inspect the script first, download it and run less mordred-install.sh before bash mordred-install.sh. The equivalent manual commands are:

# macOS
uv pip install --python ~/.hermes/hermes-agent/venv/bin/python3 \
  "mordred-hermes[macos]==0.1.0a15"

# Linux
uv pip install --python ~/.hermes/hermes-agent/venv/bin/python3 \
  "mordred-hermes[keyvault]==0.1.0a15"

See the Quickstart for the inspect-before-running sequence and first-time setup.

Optional extras:

Enable the plugins

The first configure run adds all six mordred_* entries to plugins.enabled in ~/.hermes/config.yaml. No manual edit is normally required.

Use it

Start with the standalone command:

hermes-mordred configure                 # policy / LLM / harness setup
hermes-mordred network init              # optional: Tor / VPN / clearnet

Prepare the platform key helper, then create the keyvault:

# macOS: unattended keys work in background gateways without Touch ID prompts
hermes-mordred keyvault enable-se
MORDRED_SEKEY_UNATTENDED=1 hermes-mordred keyvault init

# Linux: run these instead
hermes-mordred keyvault enable-tpm
hermes-mordred keyvault init

Turn on encryption and verify it:

hermes-mordred encryption enable env
hermes-mordred status                    # the env row should read [on] enrolled

Everyday commands:

hermes-mordred status
hermes-mordred encryption status
hermes-mordred encryption enable <env|config|memory|workspace|all>
hermes-mordred network use <tor|vpn|clearnet>
hermes-mordred network status
hermes-mordred audit tail

Once Hermes 0.19.0+ is configured and the plugins are enabled, hermes mordred <command> exposes the same command tree. On older Hermes versions, or before the first configure, keep using hermes-mordred.

See the Quickstart for expected output and the usage guide for every command and interactive prompt.

Verify discovery

hermes-mordred plugins list
# mordred_e2e / mordred_keyvault / mordred_llm_guard / mordred_network /
# mordred_privacy_check / mordred_wizard

hermes plugins list scans plugin directories and does not list package entry points. Use Mordred's command above when checking this package.

Browser-extension WebSocket gateway (preview)

The optional extension server listens on ws://127.0.0.1:7788/ext, validates the local peer and browser origin, and supports pairing, encrypted chat, history, wallet accounts, and approval-bound signing.

The one-line installer deliberately installs only the platform keyvault extra, so extension serve exits with code 2 and prints how to add the extension extra until it is installed:

uv pip install --python ~/.hermes/hermes-agent/venv/bin/python3 \
  "mordred-hermes[macos,extension,ethereum]==0.1.0a15"

How it works

The extension authenticates with a one-time pairing flow and a rotated local token. Gateway messaging uses the context-bound ENC:v3 wire and rejects plaintext Slack/Discord agent commands. Security model and protocol details are in the Extension guide.

Run it (standalone)

hermes-mordred extension serve           # foreground; Ctrl+C to stop
# second terminal
hermes-mordred extension pair

Use --port 7799 when another Hermes gateway already owns port 7788.

Standalone behavior notes

extension serve runs the real Hermes agent when its runtime is installed. It does not start automatically because Hermes currently exposes no plugin boot hook for long-running services. See the Extension guide for deployment, protocol, wallet, and troubleshooting details.

Install (development)

Use the repository's editable .venv; do not replace the production Hermes environment for normal development:

git clone https://github.com/InternetMaximalism/mordred-hermes.git
cd mordred-hermes
uv sync --all-extras

.venv/bin/python -c "import mordred_hermes; print(mordred_hermes.__file__)"
.venv/bin/hermes-mordred status

The printed module path should be under this checkout's src/. Local commands still use real ~/.hermes state unless isolated:

env HERMES_HOME=/tmp/mordred-test-home \
  .venv/bin/hermes-mordred configure

Only replace ~/.hermes/hermes-agent/venv with an editable install when an end-to-end production-profile test specifically requires it. The full workflow, including how to restore the PyPI wheel, is in development setup.

Run the standard checks:

uv run pytest -q
uv run ruff check src tests scripts
uv run ruff format --check src tests scripts
uv run mypy --strict src tools scripts/keyvault_offline_digest.py
shellcheck scripts/*.sh native/*/build.sh   # brew/apt install shellcheck

Troubleshooting

Upgrading

Package upgrades and config migration are separate operations.

Upgrade the installed package

Re-run the installer to upgrade Mordred without upgrading Hermes:

curl -fsSL https://raw.githubusercontent.com/InternetMaximalism/mordred-hermes/main/scripts/install.sh | bash

For a version-pinned upgrade, install the desired version manually into the Hermes environment:

# macOS; use [keyvault] on Linux
uv pip install --python ~/.hermes/hermes-agent/venv/bin/python3 \
  "mordred-hermes[macos]==<new-version>"

The equivalent manual command for the newest release is:

uv pip install --python ~/.hermes/hermes-agent/venv/bin/python3 \
  --upgrade-package mordred-hermes "mordred-hermes[macos]"

Restart the Hermes gateway or extension serve after upgrading.

When Hermes itself is updated

An in-place Hermes update normally preserves the Mordred wheel, but does not upgrade it. If Hermes recreates its venv, reinstall Mordred and verify the loaded path:

~/.hermes/hermes-agent/venv/bin/python3 -c \
  "import mordred_hermes; print(mordred_hermes.__file__)"

Migrate config with hermes-mordred upgrade

hermes-mordred upgrade migrates an existing Hermes or OpenClaw configuration. It is idempotent and safe to repeat:

hermes-mordred upgrade
hermes-mordred upgrade --non-interactive --policy-conflict keep-existing

Fresh installations should use configure, not upgrade.

Uninstall

Decrypt data before removing the package or keys:

hermes-mordred encryption disable all
hermes-mordred vault disable-config-decrypt
hermes-mordred encryption status          # verify every target is off

Optionally destroy profile-owned keys only after verifying the plaintext data:

hermes-mordred keyvault reset --yes        # irreversible

Remove the six mordred_* entries from plugins.enabled, then uninstall:

uv pip uninstall --python ~/.hermes/hermes-agent/venv/bin/python3 mordred-hermes
# the launcher lands next to `hermes`, wherever that is
rm -f "$(dirname "$(command -v hermes)")/hermes-mordred"

State under ~/.hermes/mordred/ and installed native helpers are intentionally left behind. Remove them manually only after confirming no encrypted data or backup still depends on them.
