Check connectivity: returns the Coolify version, the health endpoint result, the API base URL in use and whether this MCP server is read-only / allows revealing secrets. Call this first when other tools fail.

List Coolify projects with their environments (e.g. production, staging).

List servers attached to Coolify with IP, reachability and proxy type.

List applications with name, uuid, domain(s) (fqdn), status (e.g. running:healthy, exited), git repo/branch, build pack, project and environment. Use filter to narrow by name/domain substring.

Get one application's details (domains, status, git, build/start commands, ports, health check, limits, project/environment). Accepts a uuid, exact name, or a unique name/domain substring; errors with the candidates when ambiguous. Secrets (webhook secrets, basic-auth password, compose files) are never returned.

List one-click / docker-compose services (name, uuid, type, status, project/environment).

List standalone databases (name, uuid, type, status, public exposure, project/environment). Connection URLs and passwords are never returned.

List the environment variables of an application or service: key, uuid and flags (is_build_time, is_runtime, is_preview, is_literal, is_multiline, is_shown_once). Values are MASKED (short prefix + length, or "(empty)") so secrets stay out of the conversation. reveal: true returns plaintext only if the server was started with COOLIFY_ALLOW_REVEAL=1 — avoid it unless the user explicitly needs a value.

Upsert one or many environment variables on an application or service in a single call: existing keys are updated, missing keys created, identical ones left alone. Returns per key created / updated / unchanged plus which fields changed — values are never echoed. Flags you omit keep their current value on update. For applications, the main and preview copies of a key are separate (use is_preview). Use dry_run to preview. Changes only take effect after restart_application / restart_service, or deploy for build-time variables.

Delete one environment variable from an application or service, by key. For applications, is_preview selects the preview copy (default: the main one). Use dry_run to check first. Takes effect after a restart/redeploy.

Queue a (re)deployment — rebuilds and restarts. Target either resource (application/service uuid or name; comma-separate several) or tag (every resource with that Coolify tag). force: true rebuilds without cache. Returns deployment uuids; follow progress with get_deployment. Needs the token's deploy permission.

Restart an application's containers without rebuilding (picks up runtime env var changes; build-time changes need deploy). Returns a deployment uuid to follow with get_deployment.

Start (deploy) a stopped application. force rebuilds without cache; instant_deploy skips the queue.

Stop an application's containers (the site goes down until start_application or deploy). docker_cleanup (Coolify default true) prunes networks/volumes afterwards.

Restart a service (all its containers), e.g. after changing its env vars. latest: true pulls the latest images first.

With application: that app's most recent deployments (newest first, status/commit/timestamps). Without it: deployments currently queued or in progress across all servers.

Status of one deployment plus the last lines lines of its build/deploy log (default 100). Log output requires the token's read:sensitive permission.

Last lines lines (default 100) of a running application's container logs. Fails with a clear message if the app is not running.
