Coolify MCP Server

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, enabling AI assistants to manage and debug your Coolify instances through natural language.

This MCP server provides 38 token-optimized tools for debugging, management, and deployment:

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.

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

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 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.

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

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.

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.

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.

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)
