Coolify MCP Skill

This skill teaches Claude how to use the Coolify MCP server (@masonator/coolify-mcp) effectively. The server exposes ~38 token-optimized tools that wrap the Coolify API for managing self-hosted apps, databases, services, and infrastructure.

When to use this skill

Use it for any user request that touches a Coolify-managed resource, even when the user phrases the request in product terms ("redeploy the API", "restart postgres", "check why staging is unhealthy") rather than naming Coolify explicitly. If a Coolify MCP tool exists for the job, prefer it over curl, the Coolify HTTP API directly, SSH, or generic shell access — the MCP tools return summarized, token-cheap responses and include _actions hints for the natural next step.

If the Coolify MCP server is not configured in the current session, tell the user how to install it (see "Setup" below) instead of guessing.

Mental model

Coolify resources form a hierarchy: Server → Project → Environment → (Application | Database | Service). Most "smart lookup" tools accept either a UUID _or_ a human-friendly identifier (name, domain, IP), so you usually don't need to look up UUIDs first. Start broad (get_infrastructure_overview, find_issues) and narrow down with diagnose_app / diagnose_server before taking action.

The API splits "list" (cheap, summarized) from "get" (full detail). Always start with a list/overview call and only fetch full details for the specific resource you care about — this keeps responses small and fast.

Core workflow

1. Orient. If you don't already know the relevant resource, call get_infrastructure_overview (one call returns a summary of everything) or find_issues (scans for unhealthy resources). For a known target, jump straight to diagnose_app or diagnose_server.
2. Diagnose before acting. For application problems, diagnose_app <name|domain|uuid> returns status, recent logs, env vars, and deployment history in one shot. Read it before restarting or redeploying — the cause is often visible there.
3. Act. Use control to start/stop/restart, deploy to trigger a build, application / database / service for CRUD, and env_vars for environment variables.
4. Verify. After a deploy or restart, call deployment for status, then application_logs (or diagnose_app again) to confirm the resource came back healthy.
5. Report back. Summarize what you changed, link the resource by name, and surface anything from _actions that the user might want to do next.

Tool reference

Tool names below are the MCP tool identifiers exposed by @masonator/coolify-mcp. Many are dispatchers that take an action argument (e.g. application with action: "create_github").

Infrastructure & diagnostics

• get_version — Coolify API version.
• get_mcp_version — Installed MCP server version.
• get_infrastructure_overview — One-shot summary of every resource. Start here when you don't know what's there.
• find_issues — Infra-wide scan for unhealthy resources. Use when the user says something vague like "what's broken".
• diagnose_app — Status + recent logs + env vars + deployment history for one app. Accepts UUID, name, or domain.
• diagnose_server — Health, resources, domains, validation for one server. Accepts UUID, name, or IP.

Servers

list_servers, get_server, server_resources, server_domains, validate_server.

Projects & environments

projects (list/get/create/update/delete), environments (list/get/create/delete).

Applications

• list_applications, get_application
• application — dispatcher: create_public, create_github, create_key, create_dockerimage, update, delete
• application_logs — fetch app stdout/stderr
• env_vars — requires resource: "application" | "service". For application: list/create/update/delete. For service: list/create/delete (no update — service env update is not supported).
• control — start / stop / restart

Databases

• list_databases, get_database
• database — create/delete. Supported type values: postgresql, mysql, mariadb, mongodb, redis, keydb, clickhouse, dragonfly.
• database_backups — schedule + execution tracking
• control — start / stop / restart

Services

list_services, get_service, service (create/update/delete), env_vars (with resource: "service" — list/create/delete only), control.

Deployments

• list_deployments — list deployments (summary)
• deploy — trigger a deploy by tag or UUID
• deployment — status, cancel, list-by-app, paginated logs

Access & integrations

• private_keys — SSH key CRUD
• github_apps — GitHub integration CRUD
• teams — list / get / get_members / get_current / get_current_members
• cloud_tokens — Hetzner / DigitalOcean credential CRUD + validate

Docs

• search_docs — full-text search across Coolify documentation. Use this before guessing about Coolify behavior.

Output and reporting conventions

Coolify MCP responses include an _actions field suggesting the natural next operations and pagination metadata. When you finish a task, mention any _actions that look relevant so the user can decide whether to keep going. Reference resources by their human-readable name (and short UUID prefix in parentheses) rather than dumping full UUIDs — it's easier for the user to scan.

Keep responses focused on what changed, the current state, and any issues. Don't paste raw JSON unless the user asks for it.

Examples

Example 1 — "my-api is throwing 500s"

1. diagnose_app with query: "my-api" → read status, last deployment, tail of logs, env vars.
2. If a recent deploy failed: deployment (action get) with the failed deployment id and lines (optionally page) — logs are excluded by default unless lines is set.
3. If env var or config is wrong: fix with env_vars (resource: "application", action update) then deploy to redeploy.
4. After redeploy: deployment with the new deployment id and lines to watch status/log output, then confirm with diagnose_app again.

Example 2 — "what's broken across my infra"

1. find_issues → returns unhealthy resources across all servers.
2. For each, call diagnose_app or diagnose_server to get specifics.
3. Summarize a prioritized list for the user before touching anything.

Example 3 — "spin up a new postgres for the staging project"

1. projects (action list) → find the staging project and record its project_uuid and associated server_uuid.
2. environments (action list) → confirm the target environment name (for example, staging).
3. database (action create, type postgresql, server_uuid: "<server_uuid>", project_uuid: "<project_uuid>", environment_name: "staging") → create the database in that project/environment.
4. control (action start) if it doesn't auto-start, then get_database to return connection details to the user.

Setup (only if the MCP server isn't already configured)

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

Claude Desktop (claude_desktop_config.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"
      }
    }
  }
}

COOLIFY_ACCESS_TOKEN is required; COOLIFY_BASE_URL defaults to http://localhost:3000.

Safety notes

Destructive actions — delete on applications/databases/services/projects/environments, control stop on production resources, deleting private keys or cloud tokens — should be confirmed with the user before execution. When in doubt, describe what you're about to do and wait for a go-ahead. For routine reads, diagnostics, restarts of obviously broken resources, and redeploys of the user's own app on request, just do the work.
