# Kubrain > A managed Kubernetes cloud built MCP- and CLI-first. Every operation is one idempotent, cost-aware tool call your agent makes. No web console. ## Docs - [Overview](https://kubrain.dev/docs/overview/): What Kubrain is, the agent-first model, and the handful of principles that make the whole platform predictable. - [Quickstart](https://kubrain.dev/docs/quickstart/): The headline flow — from a directory of code to a running, internet-reachable app, driven entirely through Kubrain's tools. - [Core concepts](https://kubrain.dev/docs/concepts/): The handful of ideas the whole cloud rests on — tenants and tokens, the single endpoint, regions vs zones, idempotency, and how billing works. - [Guides](https://kubrain.dev/docs/guides/): Task-oriented walkthroughs — build, ship, expose, and give your app state. - [Deploy an app](https://kubrain.dev/docs/guides/deploy/): From a code directory to a running release — the deployment handle, shipping by hand or auto-building on Git push, plus promotion and rollback. - [Expose it](https://kubrain.dev/docs/guides/expose/): Put your app on a public URL with automatic TLS — ingress, hosted DNS zones, and records. - [Clusters](https://kubrain.dev/docs/guides/clusters/): Provision a cluster, reach it with kubectl, and change it — scale, resize, upgrade — all as cost-aware, async operations. - [Volumes](https://kubrain.dev/docs/guides/volumes/): Persistent storage for stateful workloads — the default StorageClass and how to design around ReadWriteOnce. - [Object storage](https://kubrain.dev/docs/guides/buckets/): S3-compatible object storage — one key pair for all your buckets, public or private. - [Container registry](https://kubrain.dev/docs/guides/registry/): A hosted registry with per-tenant namespaces — push once, and your clusters pull with no imagePullSecrets. - [Add-ons](https://kubrain.dev/docs/guides/addons/): The curated add-on catalogue — ingress, TLS, metrics, and Redis — installed cost-aware into a cluster. - [Secrets](https://kubrain.dev/docs/guides/secrets/): Give a workload credentials without ever putting them in your manifest, image, or the transcript. - [Operate](https://kubrain.dev/docs/operate/): Day-two — see what your app is doing, get paged when it breaks, and manage the fleet declaratively. - [Metrics](https://kubrain.dev/docs/operate/metrics/): Golden signals for every deployment — request rate, error rate, and p95 latency — with zero app instrumentation. - [Alerting](https://kubrain.dev/docs/operate/alerting/): Page yourself when it breaks — thresholds on golden signals, pod health, or an ingress host's uptime and TLS, delivered by webhook or email. - [Blueprints](https://kubrain.dev/docs/operate/blueprints/): Manage your whole tenant as one versioned, diffable document — export, plan, and apply your cloud. - [Reference](https://kubrain.dev/docs/reference/): The precise surface — MCP tools, CLI verbs, the kubrain.yaml manifest, pricing, and quotas. - [MCP tools](https://kubrain.dev/docs/reference/mcp-tools/): The full catalogue of Kubrain tools an agent can call — the product's actual contract. Every tool has an identical CLI verb. - [CLI](https://kubrain.dev/docs/reference/cli/): The kubrain command tree — the same engine and results as the MCP tools, for scripting and CI. - [kubrain.yaml](https://kubrain.dev/docs/reference/kubrain-yaml/): The deploy manifest that lives in your repo and travels with every release — components, build, env, service, ingress. - [Pricing](https://kubrain.dev/docs/reference/pricing/): One transparent model — billed on RAM, with two published add-on rates. Quote any shape before you create it. - [Quotas](https://kubrain.dev/docs/reference/quotas/): The two gates in front of everything that costs money or metal — your per-tenant quota and per-host capacity.
