Instances are immutable and get recreated on any server edit, so anything an
MCP server wrote to its container filesystem was lost at exactly that point.
That ruled out every stateful MCP server, docs-mcp among them: its index is a
SQLite file (better-sqlite3 + sqlite-vec) and it has no external-database mode,
so no amount of Postgres helps.
A server or template can now declare volumes. The backing store is keyed on the
server, not the instance — `mcpctl-<server>-<name>` — which is the whole point:
an instance-scoped claim would be destroyed precisely when the data needs to
survive. On Kubernetes that is a PVC ensured in the servers namespace before the
pod is created and never deleted with it; on Docker, a named volume (named, not
anonymous, so `removeContainer`'s `v: true` leaves it alone).
Claims are ReadWriteOnce, so volumes and replicas > 1 are mutually exclusive;
validation rejects that pair instead of leaving the extra replicas
unschedulable. storageClassName is omitted rather than sent empty when no class
is configured — to Kubernetes those mean different things.
Also fixes a pre-existing bug in the same path: seedTemplates dropped `runtime`,
so every PyPI-backed template seeded from YAML silently defaulted to node and
would run `npx` against a package that only exists on PyPI. `unifi-network`
declares `runtime: python` and had been seeding with runtime unset.
Templates added, all self-hosted and none needing an API key:
- duckduckgo — no backing service at all
- searxng — needs a SearXNG engine (compose profile in stack/)
- docs-mcp — open-source Context7/Ref alternative, uses the new volume

Move backup SSH keys and repo URL from MCPD_BACKUP_REPO env var to a
"backup-ssh" secret in the database. Keys are auto-generated on first
init and stored back into the secret. Also fix ERR_HTTP_HEADERS_SENT
crash caused by reply.send() without return in routes when onSend hook
is registered.

- Exempt /healthz and /health from rate limiter
- Increase rate limit from 500 to 2000 req/min
- Register backup routes even when disabled (status shows disabled)
- Guard restore endpoints with 503 when backup not configured
- Add retry with backoff on 429 in audit smoke tests

DB is source of truth with git as downstream replica. SSH key generated
on first start, all resource mutations committed as apply-compatible YAML.
Supports manual commit import, conflict resolution (DB wins), disaster
recovery (empty DB restores from git), and timeline branches on restore.

- Add warmup() to LlmProvider interface for eager subprocess startup
- ManagedVllmProvider.warmup() starts vLLM in background on project load
- ProviderRegistry.warmupAll() triggers all managed providers
- NamedProvider proxies warmup() to inner provider
- paginate stage generates LLM-powered descriptive page titles when
available, cached by content hash, falls back to generic "Page N"
- project-mcp-endpoint calls warmupAll() on router creation so vLLM
is loading while the session initializes

Introduce a Helm-chart-like template system for MCP servers. Templates are
YAML files in templates/ that get seeded into the DB on startup. Users can
browse them with `mcpctl get templates`, inspect with `mcpctl describe
template`, and instantiate with `mcpctl create server --from-template=`.
Also adds Portainer deployment scripts, mcplocal systemd service,
Streamable HTTP MCP endpoint, and RPM packaging for mcpctl-local.
