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):

{
  "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

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

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

Custom HTTP Headers (Cloudflare Zero Trust, Auth Proxies)

If your Coolify instance sits behind a Cloudflare Access tunnel or other auth-proxy middleware, pass extra headers on every outbound request with --header:

{
  "mcpServers": {
    "coolify": {
      "command": "npx",
      "args": [
        "-y",
        "@masonator/coolify-mcp",
        "--header",
        "CF-Access-Client-Id: abc123.access",
        "--header",
        "CF-Access-Client-Secret: your-secret"
      ],
      "env": {
        "COOLIFY_ACCESS_TOKEN": "your-api-token",
        "COOLIFY_BASE_URL": "https://your-coolify-instance.com"
      }
    }
  }
}

Multiple --header flags can be combined. The reserved headers Authorization and Content-Type are filtered (with a warning) to prevent silently overriding the Coolify bearer token.

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%
deployment list_for_app	~1MB	~4KB	99.6%

HATEOAS-style Response Actions

Responses include contextual _actions suggesting relevant next steps:

{
  "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:

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