## What it does

cpln adds Control Plane domain guidance, production safeguards, and MCP tools to Claude Code. Its skills cover CLI workflows, access control, networking, autoscaling, and storage. Guided agents handle workload troubleshooting and migrations from Kubernetes, Compose, or Helm. You can ask for a domain with automatic TLS or credential-free S3 access for a workload.

The plugin connects to a hosted MCP server. Sign in and choose which Control Plane organizations the assistant can access; that access counts as production access. Deleting resources, changing volumes, and applying changes to production require your explicit confirmation. Secret values stay out of chat: users enter them in the Console.

\`CPLN_TOKEN`, `CPLN_ORG`, `CPLN_GVC`, and `CPLN_PROFILE` are optional and apply only to certain CLI workflows, such as CI/CD, Terraform, and Pulumi. To install through Claude Code's community marketplace, run these commands in order:

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install cpln@claude-community
```

## When to use it
- deploy a workload on Control Plane
- diagnose repeated workload restarts
- configure a domain with automatic TLS
- migrate Kubernetes configuration to Control Plane
- grant a workload S3 access without IAM keys

## Example prompts
- Find why the `payments-api` workload in `production` keeps restarting.
- Set up `app.example.com` with automatic TLS for the `web` workload.
- Migrate `kustomization.yaml` to Control Plane and apply it to `staging` after I confirm.

# Control Plane AI Plugin

Run containerized workloads across AWS, GCP, Azure, OCI, and your own hardware under one API. It loads Control Plane's domain knowledge, production guardrails, and live MCP tools into Claude Code, Codex, and Antigravity CLI so your assistant can deploy, troubleshoot, secure, and migrate workloads with verified `cpln` commands.

## Installation

### Claude Code

```text
/plugin marketplace add https://github.com/controlplane-com/ai-plugin.git
/plugin install cpln@controlplane
/reload-plugins
```

Update with `/plugin marketplace update controlplane` then `/reload-plugins` (third-party marketplaces don't auto-update unless you enable it in `/plugin` → **Marketplaces**).

Alternatively, install from [Anthropic's community plugin marketplace](https://github.com/anthropics/claude-plugins-community), where every listing has passed Anthropic's review:

```text
/plugin marketplace add anthropics/claude-plugins-community
/plugin install cpln@claude-community
/reload-plugins
```

### Codex

```bash
codex plugin marketplace add https://github.com/controlplane-com/ai-plugin.git
```

Start Codex, open `/plugins`, and install `cpln`. The MCP handshake supplies the core rules. Local installations also include optional session hooks, which must be reviewed and trusted in Codex before they run.

Update with `codex plugin marketplace upgrade controlplane`, then restart Codex.

### Antigravity CLI

Install the plugin with Antigravity CLI (`agy`):

```bash
agy plugin install https://github.com/controlplane-com/ai-plugin/plugins/cpln
```

### Generic MCP client

Point any other MCP client at the hosted server:

```json
{
  "mcpServers": {
    "cpln": {
      "type": "http",
      "url": "https://mcp.cpln.io/mcp"
    }
  }
}
```

The bare URL serves the default `core` tool set. A client that loads tools on demand can add `?toolsets=full` for every tool.

## Authentication

MCP uses OAuth 2.1 + PKCE. Sign in to let the assistant act on your Control Plane organizations — you choose which orgs it may operate on, and the token is scoped to those orgs and enforced server-side on every call. Sign in again to change the grant. Treat MCP access as production access to the orgs you grant. How to sign in:

- **Claude Code** — `/mcp`, select `cpln`, sign in (or `claude mcp login cpln`).
- **Codex** — `codex mcp login cpln`.
- **Antigravity CLI** — `/mcp`, select `cpln`, authenticate.

## Environment variables

Optional — only for the `cpln` CLI workflows some skills generate (CI/CD, Terraform, Pulumi). See `.env.example`.

| Variable       | Purpose                                                 |
| -------------- | ------------------------------------------------------- |
| `CPLN_TOKEN`   | Service-account token for `cpln` CLI calls (sensitive). |
| `CPLN_ORG`     | Default organization.                                   |
| `CPLN_GVC`     | Default GVC.                                            |
| `CPLN_PROFILE` | Local `cpln` CLI profile.                               |

## Usage

Ask in natural language — the assistant routes to the right skill or agent:

- "Troubleshoot why my `payments-api` workload in `production` keeps restarting."
- "Put `app.example.com` in front of my `web` workload with auto-TLS."
- "Give my `analytics` workload credential-free read access to S3 bucket `prod-event-logs` — no IAM keys."
- "Provision a production Postgres with HA failover and S3 backups."
- "Convert this `kustomization.yaml` to Control Plane and apply it to `staging` after I confirm."
