Dockhold

List the apps in your Dockhold account, with each app's id, status, URL, and source repo. Call this first whenever the user asks about their apps, or when you need an app_id for any other tool.

Get detailed status for one app: deploy status, URL, last deployed commit, and any error message. Call this to check whether a deploy has finished, to get an app's live URL, or to see why an app is in error. Status DEPLOYING with ready_at set means the new version is already reachable at its URL and Dockhold is confirming it stays up; the user can open it now. It moves to RUNNING once confirmed, or to ERROR with an error_message if it crashed.

Get the most recent runtime logs for one app. Call this when an app is crashing, returning errors, or a deploy succeeded but the app misbehaves: the logs usually name the cause.

Deploy a GitHub repository as a live web app on Dockhold. Call this when the user wants to put an app online, get a shareable HTTPS URL, or host a demo. Returns the new app id. Two paths: a PUBLIC repo needs only repo_url; a PRIVATE repo needs repo_url plus github_installation_id (call list_github_repos first, each repo comes with the installation_id to pass here). Deploying a private repo turns on auto-deploy: future pushes to that repo redeploy the app automatically. The app builds and comes online automatically; poll get_app_status to watch it. Set memory_mb to size the app's compute, one of the values get_resource_usage reports under compute.steps_mb: 256 MB fits a static site or a small API, 512 MB fits a typical Node or Python web app, and anything that holds data in memory needs more. Omit it and the app gets the minimum slice (256 MB) so it doesn't take your whole compute pool; resize_app changes the size later with no rebuild, applied as a rolling update that replaces the app's instances. The response reports memory_mb (what this app got) and compute_available_mb (what's left in your pool), so size the next app off that. This tool needs a GitHub repo URL: if the code only exists locally (no repo), it cannot be used here, and the user should run `npx dockhold login` then `npx dockhold deploy` in the project folder instead. Requires a token with the deploy scope.

Restart an existing app (rolling restart with zero downtime). Call this after changing configuration, or to recover an app that is stuck or misbehaving. It restarts the version already running. It does not build or pull new code: call rebuild_app for that. If this app has storage, it is stopped and started again instead, so it is unreachable for a few seconds.

Set a single environment variable on an app and roll it out. Call this when an app needs plain configuration such as LOG_LEVEL or a feature flag. For secrets (API keys, passwords, tokens) call set_app_secret instead: this tool rejects secret-looking keys.

Remove a single plain environment variable from an app and roll it out. The pair to set_app_variable; setting a variable to an empty string is not the same thing to most apps. Variables Dockhold sets itself (PORT, DATABASE_URL, DATA_DIR and the app's address) cannot be removed. For a secret, call unset_app_secret instead.

Show your account's compute, database-RAM, and storage pools: how much you've bought, how much is used, and how much is free, plus every app's current size. Call this before any resize tool (the allowed sizes come from its steps fields), and to explain to the user why an app ran out of memory or a deploy was refused for capacity.

Change how much memory one app gets. Call this when an app is running out of memory (OOM) or the user asks to make an app bigger or smaller. memory_mb must be one of the sizes get_resource_usage reports under compute.steps_mb, and the new size has to fit your available compute pool (call get_resource_usage first). Applied with a zero-downtime rolling update. If this app has storage, it is stopped and started again instead, so it is unreachable for a few seconds.

Change how much memory an app's managed database gets. Call this when the database is slow or out of memory. db_ram_mb must be one of the sizes get_resource_usage reports under db_ram.steps_mb and fit your database-RAM pool. WARNING: the database restarts briefly to apply the new size, so the app loses its database connection for a few seconds. Only works if the app has a managed database.

Grow the disk of an app's managed database. Call this when the database is running out of disk space. GROW-ONLY: you can increase storage but never shrink it. storage_gb must be one of the sizes get_resource_usage reports under storage.steps_gb and fit your storage pool. Applied online with no database restart. Only works if the app has a managed database.

Give an app storage that survives restarts and deploys, or grow the storage it already has. Call this when the app has to keep files: a SQLite database file, uploads, or anything the user expects to still be there tomorrow. The app reads and writes the folder at the path in the DATA_DIR environment variable, which Dockhold sets; anything written outside DATA_DIR is scratch space and is lost on the next restart. size_gb must be one of the sizes get_resource_usage reports under volume.steps_gb and has to fit your storage pool, which is the same pool a managed database draws on, so call get_resource_usage first. Storage can grow but never shrink. Three things to tell the user before calling this: an app with storage runs as a single copy, it cannot have scheduled tasks, and from now on each deploy stops the running version before the new one starts, so the app is unreachable for a few seconds. Write the app to save its files when it receives SIGTERM.

Remove an app's storage and erase every file on it. This destroys data permanently: there is no undo and no backup. Ask the user to confirm in their own words first, then pass confirm true. Call it when the user asks for the storage to go, or when they want something storage rules out: running more than one copy of the app, or a scheduled task. Afterwards the app is back to scratch space, where anything it writes is lost on the next restart.

Store a sensitive value (an API key, a token, a password, a connection string) for one app. Use this instead of set_app_variable whenever the value would be damaging if someone else read it. The value is encrypted at rest, is injected into the app's environment under the name you give, and the app restarts to pick it up. Storing a secret takes effect on the next boot, so call this before telling the user the app is ready. This tool never reads a value back: there is no way to retrieve a stored secret through this connection, only through the dashboard while signed in. Two things to tell the user before you call it. First, this token can write secrets to every app on their account, not only this one. Second, any value they give you has passed through your context, so prefer a value you read from a local file such as .env over one you asked them to type into the chat, and suggest they rotate anything that was pasted. If the vault key name is already used by a different app, this call is refused rather than overwriting it, and the message tells you what to pass as vault_key_name.

Stop injecting a stored secret into one app. The app restarts without it, so call this only when the app no longer needs that variable. The stored value stays in the account vault and any other app using it keeps working; deleting the stored value itself is a dashboard action. Do not report the secret as deleted, report it as removed from this app.

Attach a secret that is already stored in the account vault to one app, under the environment variable name the app reads, and restart the app. Call this when the user says the key already exists in Dockhold (call list_secrets to see the names), or when a second app should use the same stored value: nothing passes through your context and no value is stored again. Sharing one entry between apps means they share the value; if the user wants separate credentials per app, store a new value with set_app_secret under a distinct vault_key_name instead. This token can attach any secret on the account to any app on the account.

List the names of every secret stored in the account vault and how many apps use each, so you can attach an existing one with bind_app_secret instead of asking the user for the value again. Returns names and counts only. Secret values cannot be read back through this connection at all.

List the names of the secrets attached to one app, so you can tell which ones an app already has before setting another. Returns names only. Secret values cannot be read back through this connection at all.

List the GitHub repositories you have connected to Dockhold, across every installation. Call this before deploy_app when the target repo is private, or when the user asks which repos they can deploy. Each repo comes with its installation_id: pass that (with the repo's clone URL) to deploy_app to deploy a PRIVATE repository. Public repos don't need it.

Builds the app again from the latest commit of its repository (or its last upload) and deploys it when the build passes. Use after a failed build, or to ship new commits when auto-deploy is off. One build per app at a time; limits on builds running and builds per hour; a refusal says when to try again. Poll get_app_status.

Deploy several connected services in one go (e.g. a frontend + an API). Call this when the user's project is split across multiple repos that must talk to each other; for a single repo use deploy_app. Each service is a public GitHub repo that gets its own URL. Wire them by setting an env var to the exact token ${services.<otherServiceName>.url} — Dockhold injects that service's live URL once it deploys. Give the backend its own database with "db":"enable" (DATABASE_URL is injected; a pure frontend doesn't need one). Builds run in parallel; poll get_app_status with each returned app_id.
