> **The most comprehensive MCP server for Coolify** - 38 optimized tools, smart diagnostics, documentation search, and batch operations for managing your self-hosted PaaS through AI assistants.

A Model Context Protocol (MCP) server for [Coolify](https://coolify.io/), enabling AI assistants to manage and debug your Coolify instances through natural language.

## Features

### Token-Optimized Design

The server uses **85% fewer tokens** than a naive implementation (6,600 vs 43,000) by consolidating related operations into single tools with action parameters. This prevents context window exhaustion in AI assistants.

## Installation

### Prerequisites

- Node.js >= 18
- A running Coolify instance (tested with v4.0.0-beta.460)
- Coolify API access token (generate in Coolify Settings > API)

### Claude Desktop

Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS):

```json
{
  "mcpServers": {
    "coolify": {
      "command": "npx",
      "args": ["-y", "@masonator/coolify-mcp"],
      "env": {
        "COOLIFY_ACCESS_TOKEN": "your-api-token",
        "COOLIFY_BASE_URL": "https://your-coolify-instance.com"
      }
    }
  }
}
```

### Claude Code

```bash
claude mcp add coolify \
  -e COOLIFY_BASE_URL="https://your-coolify-instance.com" \
  -e COOLIFY_ACCESS_TOKEN="your-api-token" \
  -- npx @masonator/coolify-mcp@latest
```

> **Note:** Use `@latest` tag (not `-y` flag) for reliable startup in Claude Code CLI.

### Cursor

```bash
env COOLIFY_ACCESS_TOKEN=your-api-token COOLIFY_BASE_URL=https://your-coolify-instance.com npx -y @masonator/coolify-mcp
```

## Context-Optimized Responses

### Why This Matters

The Coolify API returns extremely verbose responses - a single application can contain 91 fields including embedded 3KB server objects and 47KB docker-compose files. When listing 20+ applications, responses can exceed 200KB, which quickly exhausts the context window of AI assistants like Claude Desktop.

**This MCP server solves this by returning optimized summaries by default.**

### How It Works

| Tool Type                     | Returns                                  | Use Case                            |
| ----------------------------- | ---------------------------------------- | ----------------------------------- |
| `list_*`                      | Summaries only (uuid, name, status, etc) | Discovery, finding resources        |
| `get_*`                       | Full details for a single resource       | Deep inspection, debugging          |
| `get_infrastructure_overview` | All resources summarized in one call     | Start here to understand your setup |

### Response Size Comparison

| Endpoint              | Full Response | Summary Response | Reduction |
| --------------------- | ------------- | ---------------- | --------- |
| list_applications     | ~170KB        | ~4.4KB           | **97%**   |
| list_services         | ~367KB        | ~1.2KB           | **99%**   |
| list_servers          | ~4KB          | ~0.4KB           | **90%**   |
| list_application_envs | ~3KB/var      | ~0.1KB/var       | **97%**   |
| deployment get        | ~13KB         | ~1KB             | **92%**   |

### HATEOAS-style Response Actions

Responses include contextual `_actions` suggesting relevant next steps:

```json
{
  "data": { "uuid": "abc123", "status": "running" },
  "_actions": [
    { "tool": "application_logs", "args": { "uuid": "abc123" }, "hint": "View logs" },
    {
      "tool": "control",
      "args": { "resource": "application", "action": "restart", "uuid": "abc123" },
      "hint": "Restart"
    }
  ],
  "_pagination": { "next": { "tool": "list_applications", "args": { "page": 2 } } }
}
```

This helps AI assistants understand logical next steps without consuming extra tokens.

### Recommended Workflow

1. **Start with overview**: `get_infrastructure_overview` - see everything at once
2. **Find your target**: `list_applications` - get UUIDs of what you need
3. **Dive deep**: `get_application(uuid)` - full details for one resource
4. **Take action**: `control(resource: 'application', action: 'restart')`, `application_logs(uuid)`, etc.

### Pagination

All list endpoints still support optional pagination for very large deployments:

```bash
# Get page 2 with 10 items per page
list_applications(page=2, per_page=10)
```
