feat: add MCP server templates and deployment infrastructure 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.

feat(servers): persistent volumes + self-hosted web search and docs templates 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 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017BMXdb2qZbPSh8Q7XpTyjB 2026-08-09 18:17:32 +01:00
