noconnorandClaude Opus 4.8 11f88ad3a9 mcp-config: render the SAME MCP servers into Hermes' config 
Hermes had no MCP servers at all -- no mcp_servers: key -- so "use the gitea
MCP" had nothing to call. The model said so ("there's no Gitea-specific skill"),
which was true, and then looped reaching for the browser as the only way in.

The obvious fix -- paste a gitea block into ~/.hermes/config.yaml -- is the
wrong one: it makes a SECOND definition of a server this repo already defines
once, free to drift (one pinned to gitea-mcp@0.0.10, the other to whatever got
typed). README already calls this out: "all MCP servers are defined here", and
listed other clients as "not done yet". So render, don't duplicate: sync.sh
already translates LiteLLM's /model/info into opencode's schema; this is the
same move into Hermes' schema, from opencode.gateway.json's mcp block. Add a
server once, both clients get it within the same TTL.

Not a shared server PROCESS, which is what "use the same one" would imply: MCP
stdio servers are subprocesses spawned per client over stdin/stdout and dying
with it. Each client running its own `npx -y <pkg>` is the design -- same
package, same pinned version, same per-user credential, same identity. Sharing
one process would need a persistent daemon plus a stdio->HTTP bridge, for
nothing. And it stays client-side: the gateway hosts no MCP servers on purpose
(values.yaml:892; user-scoped APIs, no shared tokens), and gitea-mcp hard-exits
without a token so LiteLLM's headerless listing never registers it anyway.

Translation notes: Hermes' `command` must be a STRING (a list stringifies to
"['npx', '-y']" and fails at exec), so opencode's argv list splits into
command + args. `{env:VAR}` becomes `${VAR}` -- both by-name, so no secret is
written to either file. Hermes gives an MCP child only a filtered baseline env,
so every secret must be listed in env:, which the rendered block does. Nothing
is added to platform_toolsets: MCP servers auto-enable by name, and listing some
would turn it into an allowlist.

Rendered names are recorded in ~/.config/mcp-sync/hermes-managed.json so a
server dropped upstream is dropped from Hermes, while servers the user added by
hand -- never in the manifest -- are left alone. Only writes when the result
changes, skips silently when Hermes isn't installed, warns when PyYAML is
missing (an absent MCP block is invisible rather than obviously broken).

Verified via Hermes' own discovery: 72 tools register -- 30 gitea (incl.
issue__list) and 42 proxmox -- with ${GITEA_KEY} / ${PROXMOX_MCP_*} resolving
and no secret in config.yaml.

Also fixes a stale README claim that MCP tools come from the gateway's /mcp
endpoint; they never do, and values.yaml:892 says why.

Raw Blame History

dotfiles

Configures fresh VMs (RHEL-family or Debian-family) with a consistent environment. Run ./bootstrap.sh (or curl-pipe it) to apply everything; each module also runs standalone and is safe to re-run.

Quick start

On a fresh box, apply everything with one command:

curl -fsSL https://git.nic-oconnor.com/public/dotfiles/raw/branch/main/bootstrap.sh | sh

When piped like this (no local checkout), bootstrap.sh clones the repo to ~/.dotfiles and runs from there, so git must be installed first. Re-running the command updates the checkout (git pull) and re-applies every module. Override the destination or source with DOTFILES_DIR / DOTFILES_REPO.

Already have a clone? Just run it directly:

./bootstrap.sh

Modules

  • zsh/ — installs zsh + oh-my-zsh, drops a managed ~/.zshrc (robbyrussell theme, git plugin), and sets zsh as the login shell. The managed rc sources ~/.zshrc.local last for per-machine customizations (see below).

  • git/ — sets git user.name/user.email and configures credential.helper store (plaintext ~/.git-credentials, 0600) for HTTPS auth.

  • docker/ — installs full (rootful) Docker Engine from Docker's upstream package repo (get.docker.com on Debian-family; the docker-ce repo wired up directly on RHEL-family, since the convenience script rejects EL rebuilds like Oracle Linux by name), enables the service (systemd hosts), and adds the invoking user to the docker group (takes effect at next login). No-ops where a rootless Docker daemon is already running (e.g. Kasm) so it never fights that setup. Uses sudo.

  • bin/ — installs userland devops CLIs as self-contained, statically linked release binaries into ~/.local/bin: jq, kubectl, helm, k9s, kubectx/kubens, stern, yq, OpenTofu, terragrunt, task (go-task, the Taskfile runner), the 1Password CLI op for secrets storage, the opencode coding agent, zarf (DevSecOps for Offline and Airgapped Kubernetes), and packer (HashiCorp's infrastructure build tool). kind is installed only when full (non-rootless) Docker is available — it doesn't work against rootless Docker, so it is skipped on Kasm. No sudo, nothing outside $HOME, so tools persist across Kasm redeploys with no reinstall. Idempotent: each tool records its version under ~/.local/bin/.versions and is skipped when the pinned version is already present. zsh/zshrc puts ~/.local/bin on PATH.

    opencode is configured by mcp-config/: it points at the covert-gpt LiteLLM gateway (https://llm.covert-gpt.com/v1) for models. MCP tools do NOT come from the gateway — it hosts no MCP servers, deliberately; they run client-side under your own credentials (see mcp-config/README.md). Run mcp-config/install.sh once to store your LiteLLM key and enable config sync — without it, opencode installs but can't reach the gateway.

  • ansible/ — installs Ansible into a virtualenv at ~/.local/opt/ansible (it's Python, not a single binary) and symlinks its CLIs into ~/.local/bin. Persists across redeploys; only rebuilt when the venv is missing or broken. Building it may install python3/python3-venv via the system package manager (the one place this module uses sudo).

  • docker-rootless-cgroup/ — on systemd-less hosts (e.g. Kasm), hand-delegates cgroup v2 controllers to the rootless Docker daemon so per-container cgroups work (rootless Docker otherwise comes up with CgroupDriver=none). Uses sudo for host cgroup writes and restarts the daemon; no-ops on systemd or non-rootless hosts. Re-run at each bootstrap (the cgroup layout resets on redeploy); its PATH shim lives in $HOME.

  • mcp-config/ — shared MCP gateway config sync for laptops (LiteLLM / opencode). Independent of bootstrap.sh; see its own README.

Per-machine customizations and secrets

~/.zshrc is managed — bootstrap overwrites it, so never hand-edit it. Per-machine settings and secrets go in ~/.zshrc.local, which the managed rc sources last (so it can override anything) and bootstrap never touches:

cp zsh/zshrc.local.example ~/.zshrc.local && chmod 600 ~/.zshrc.local

Variables modules look for:

  • GITEA_KEY — personal access token for git.nic-oconnor.com (API/CLI use; HTTPS git auth itself goes through git/'s credential helper).

  • LITELLM_KEY — covert-gpt gateway key used by opencode. Normally you don't set this by hand: run mcp-config/install.sh once and its shell hook exports it from ~/.config/mcp-sync/key. Set it in ~/.zshrc.local only on a box without mcp-sync.

  • OP_SERVICE_ACCOUNT_TOKEN — 1Password service-account token for non-interactive op read / op run.

  • GITEA_KEY, PROXMOX_MCP_TOKEN_ID, PROXMOX_MCP_TOKEN_SECRET — your own credentials for the client-side MCP servers in mcp-config/. opencode reads them from your environment ({env:VAR}) and passes them to the MCP server it spawns, so the tools act as you. Keep them in ~/.zshrc.local; they are never written into any config file.

    These are NOT used by ai-k8s-iac / task up: the LiteLLM gateway hosts no MCP servers and stores no MCP credentials. See mcp-config/README.md.

  • hermes/ — installs Hermes Agent (Nous Research's self-improving AI agent) via npm. Hermes uses npx to spawn and downloads the Python hermes-agent from PyPI. Everything under $HOME, so it survives Kasm redeploys.

    It then merges hermes/gateway.yaml into ~/.hermes/config.yaml, wiring Hermes to the covert-gpt LiteLLM gateway as a named custom provider. The merge is idempotent and touches only that provider entry, so the rest of your personal config is left alone; model.default / model.provider are seeded only on a fresh box. Unlike mcp-config/, this deploys at BOOTSTRAP time, not per-shell — re-run hermes/install.sh to pick up a gateway.yaml change.

    Depends on mcp-config/install.sh having run: gateway.yaml names the key (key_env: LITELLM_KEY) but never contains it, and mcp-config/sync.sh is what exports LITELLM_KEY into your shell. Without it Hermes 401s.

Secrets never go in this repo or in zsh/zshrc — that file is shared config applied to every box.

lib/os-detect.sh provides shared package-manager detection (dnf/yum vs apt); lib/fetch.sh provides arch detection and binary-download helpers. Both are used by module install scripts.
