Coolify MCP Server

coolify-mcp

MCP server for Coolify API - enables full deployment workflows from zero to production.

Targets the Coolify v4.1.2 API. Types and schemas are generated directly from Coolify's official OpenAPI spec, so tool inputs always match what the API actually accepts.

Features

• Full Deployment Workflow: Create projects, environments, servers, and applications from scratch
• 5 Application Types: one createApplication tool covers public git, GitHub App, Deploy Key, Dockerfile, and Docker Image sources — plus Docker Compose deployments via createService (since Coolify v4.1, compose deployments are services)
• Environment Management: Full CRUD for environment variables with secret masking
• Deployment Control: Deploy (optionally waiting for the terminal status, with a log tail on failure), start, stop, restart applications
• Diagnostics: diagnoseApp finds an app by UUID, name, or domain and aggregates status, recent deployments, failure log tails, runtime logs, and suggested next actions
• Docs Search: searchDocs runs full-text search across the official Coolify documentation from a bundled local index — no network needed
• Security: Write protection, secret redaction, and MCP annotations (readOnlyHint/destructiveHint) so clients can auto-approve reads and gate destructive calls
• Near-full API coverage: databases (8 engines, backups, envs), services, storages, scheduled tasks, teams, previews, servers, SSH keys, and GitHub Apps
• Token-efficient: 65 tools whose definitions cost ~9k tokens of context, with strict runtime validation against schemas generated from Coolify's OpenAPI spec

Requirements

• Node 18+
• A Coolify API token (Settings > API in your Coolify dashboard)

Install

Claude Desktop, one-click: download coolify-mcp.mcpb from the latest release and drag it into Settings → Extensions. You'll be prompted for your Coolify URL and token — no Node install, no JSON editing.

Via npm:

npm install -g @fndchagas/coolify-mcp
# or
npx -y @fndchagas/coolify-mcp

Quick Start

Claude Code CLI

claude mcp add coolify \
  --env COOLIFY_BASE_URL="https://coolify.example.com/api/v1" \
  --env COOLIFY_TOKEN="<token>" \
  -- npx -y @fndchagas/coolify-mcp

OpenAI Codex CLI

codex mcp add coolify \
  --env COOLIFY_BASE_URL="https://coolify.example.com/api/v1" \
  --env COOLIFY_TOKEN="<token>" \
  -- npx -y @fndchagas/coolify-mcp

Or edit ~/.codex/config.toml:

[mcp_servers.coolify]
command = "npx"
args = ["-y", "@fndchagas/coolify-mcp"]
env = { COOLIFY_BASE_URL = "https://coolify.example.com/api/v1", COOLIFY_TOKEN = "<token>" }

Manual Configuration (~/.mcp.json)

{
  "mcpServers": {
    "coolify": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@fndchagas/coolify-mcp"],
      "env": {
        "COOLIFY_BASE_URL": "https://coolify.example.com/api/v1",
        "COOLIFY_TOKEN": "<token>",
        "COOLIFY_ALLOW_WRITE": "true"
      }
    }
  }
}

Environment Variables

Deploy from Zero

With this MCP, you can deploy an application from scratch:

1. listProjects / createProject       → Get or create a project
2. listEnvironments / createEnvironment → Get or create an environment
3. listServers / createServer         → Get or create a server
4. listPrivateKeys / createPrivateKey → Get or create SSH keys (if needed)
5. createApplication (type: public)   → Create the application
6. applicationEnvs (action: upsert)   → Configure environment variables
7. deploy                             → Trigger deployment

Applications - Read

Applications - Create

Docker Compose deployments are created with createService passing docker_compose_raw — since Coolify v4.1 they are services, not applications.

Applications - Manage

Environment Variables

Database and service env vars have their own tools: databaseEnvs and serviceEnvs.

Security Features

Write Protection

Disable all write operations:

COOLIFY_ALLOW_WRITE=false

Secret Masking

• Environment variable values are masked by default
• Database credentials are redacted
• Use showSecrets: true only when necessary

HTTP Transport Hardening

The HTTP transport binds to 127.0.0.1 by default. To expose it beyond loopback, set MCP_HTTP_TOKEN — every request to /mcp must then carry Authorization: Bearer <token> (checked in constant time) — and the bind switches to 0.0.0.0 (override with MCP_HTTP_HOST). Binding to a non-loopback host without a token logs a loud warning: anyone who can reach the port controls your Coolify instance.

Human Confirmation on Destructive Deletes

On MCP clients that support elicitation (Claude Code, VS Code Copilot), deleting a project, application, database, service, server, or private key asks you to confirm first, stating what will be lost. Clients without elicitation behave exactly as before. A decline, cancel, or timeout aborts the call; set COOLIFY_MCP_ELICITATION=off to disable the prompts entirely.

MCP Client Examples

HTTP Client

import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { StreamableHTTPClientTransport } from '@modelcontextprotocol/sdk/client/streamableHttp.js';

const client = new Client({ name: 'coolify-client', version: '1.0.0' });
const transport = new StreamableHTTPClientTransport(
  new URL('http://localhost:7331/mcp')
);

await client.connect(transport);

// List all applications
const apps = await client.callTool({
  name: 'listApplications',
  arguments: {},
});
console.log(apps.structuredContent);

// Deploy an application
const deploy = await client.callTool({
  name: 'deploy',
  arguments: { uuid: 'your-app-uuid' },
});
console.log(deploy.structuredContent);

await client.close();

Stdio Client

import { Client } from '@modelcontextprotocol/sdk/client/index.js';
import { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js';

const client = new Client({ name: 'coolify-client', version: '1.0.0' });
const transport = new StdioClientTransport({
  command: 'npx',
  args: ['-y', '@fndchagas/coolify-mcp'],
  env: {
    COOLIFY_BASE_URL: 'https://coolify.example.com/api/v1',

});

await client.connect(transport);
