Vibn AI Capabilities

The full set of actions an AI agent can take on behalf of a Vibn workspace, along with the REST endpoints, MCP tools, and safety rails that back them.

Audience: agent authors, Cursor rule writers, MCP tool designers, and anyone building on the Vibn control plane.

Scope: everything an agent sees through https://vibnai.com/api/* and the /api/mcp bridge. No Firestore, no internal agent orchestration — just the tenant-safe capability surface.

---

1. Mental model

Every capability in this document operates on a single workspace. A workspace is Vibn's tenant boundary and maps 1:1 to:

Vibn concept	External identity	Example (mark)
Workspace	vibn_workspaces.slug	mark
Gitea org	gitea_org	vibn-mark
Gitea bot user	gitea_bot_username	mark-bot
SSH deploy keypair	coolify_private_key_uuid + gitea_bot_ssh_key_id	registered on both sides
Coolify project	coolify_project_uuid	vibn-ws-mark
Coolify environment	coolify_environment_name	production
Domain namespace	*.{slug}.vibnai.com	*.mark.vibnai.com
AI token	vibn_sk_…	one per agent/device

A single agent token can only act on the workspace it was minted for. Cross- workspace access is structurally impossible — enforced in lib/coolify.ts by matching every Coolify resource's environment_id against the workspace's project environments (ensureResourceInProject).

The three views

All capabilities roll up into three user-facing surfaces:

• Code — every Gitea repo under vibn-{slug}/.
• Live — every Coolify app/database/service in vibn-ws-{slug}, each reachable under *.{slug}.vibnai.com.
• IDE — Browser-based agent workspace sessions (outside the scope of this doc).

---

2. Authentication

Every agent-facing endpoint accepts either:

• Authorization: Bearer vibn_sk_<base64url> — a workspace-scoped API key minted in the settings panel. Stored as a sha256 hash server-side; the plaintext is shown exactly once on creation. Can be revoked at any time.
• A NextAuth session cookie — used for the dashboard UI and for browser debugging. Not suitable for long-running agents.

Helper: requireWorkspacePrincipal() resolves either to a WorkspacePrincipal { workspace, user?, source }.

403 on a tenant mismatch means: the token is valid, but the resource belongs to another workspace. The agent should stop and ask the user.

---

3. MCP surface

The MCP bridge lives at POST https://vibnai.com/api/mcp. It takes JSON-over-HTTP bodies shaped like:

{ "tool": "<tool-name>", "params": { /* tool-specific */ } }

The Cursor / Claude Desktop config block is auto-generated in the settings panel and looks like:

{
  "mcpServers": {
    "vibn-mark": {
      "url": "https://vibnai.com/api/mcp",
      "headers": { "Authorization": "Bearer vibn_sk_…" }
    }
  }
}

GET /api/mcp returns a self-description with the current tool list. Version: 2.1.0.

3.1 Workspace & identity tools

Tool	Purpose	Params
workspace.describe	Returns slug, Coolify project uuid, Gitea org, provision status.	—
gitea.credentials	Returns the bot's username, PAT, clone URL template, and SSH remote template. Use this for every git clone/push — never other credentials.	—

3.2 Project tools

Tool	Purpose	Params
projects.list	Lists Vibn projects (PRDs, imports, etc.) in the workspace.	—
projects.get	Single project details.	{ projectId }

3.3 Application tools

Tool	Purpose	Params
apps.list	All Coolify apps in the workspace.	—
apps.get	Single app details (status, fqdn, domains, git info).	{ uuid }
apps.create	Create a Coolify app from a Gitea repo in the workspace's org. Clones over HTTPS with the workspace bot's PAT embedded in the URL — SSH is not used because Gitea's SSH isn't reachable on the default port. Auto-domain {name}.{slug}.vibnai.com.	{ repo, branch?, name?, ports?, buildPack?, domain?, envs?, instantDeploy?, dockerComposeLocation?, dockerfileLocation?, baseDirectory? }
apps.update	PATCH a whitelisted set of fields (name, description, git branch/commit, ports, build commands, base directory, Dockerfile location, docker-compose location…). Returns applied, ignored, and rerouted arrays so the agent can see exactly what persisted; setting fqdn/domains/docker_compose_domains returns a rerouted entry pointing at apps.domains.set, and setting git_repository returns one pointing at apps.rewire_git.	{ uuid, patch }
apps.rewire_git	Re-point an app's git_repository at the canonical HTTPS+PAT clone URL. Use to recover older apps that were created with SSH URLs, or to refresh a rotated bot PAT.	{ uuid, repo? } — repo optional; inferred from current URL if omitted
apps.delete	Destroy the app. Volumes kept by default.	{ uuid, confirm } — confirm must equal the app's exact name
apps.deploy	Trigger a new deployment.	{ uuid, force? }
apps.deployments	List recent deployments + status.	{ uuid }
apps.logs	Runtime logs for a running app. Compose-aware: returns per-service logs for dockercompose build packs, single stream for dockerfile/nixpacks. Includes container status and any diagnostic warnings.	{ uuid, service?, lines? } — service filter (compose only), lines default 200, max 5000
apps.exec	Run a one-shot command inside an app container (via docker exec on the Coolify host). Compose-aware: pass service when the app has >1 container. Returns { container, service, code, stdout, stderr, truncated, durationMs, containerHealth }. Default timeout 60s (max 10 min); default output cap 1 MB (max 5 MB). Command is run through sh -lc so shell syntax works. Use this for database migrations, seeds, CLI invocations, and ad-hoc debugging. Every call is audit-logged (command + target, not output).	{ uuid, command, service?, user?, workdir?, timeout_ms?, max_bytes? }
apps.domains.list	Current domain set.	{ uuid }
apps.domains.set	Replace the domain set. All entries must end with .{slug}.vibnai.com. Compose-aware: for dockercompose apps the domain is attached to a specific service (server by default; override with service).	{ uuid, domains: string[], service? }
apps.envs.list	List env vars. Values returned are redacted for shown-once secrets.	{ uuid }
apps.envs.upsert	Create or update an env var. is_build_time is ignored — Coolify derives build-vs-runtime from Dockerfile ARG usage.	{ uuid, key, value, isPreview?, isMultiline?, isLiteral?, isShownOnce? }
apps.envs.delete	Delete an env var.	{ uuid, key }

3.4 Database tools

Tool	Purpose	Params
databases.list	All databases in the workspace, across all flavors.	—
databases.create	Provision a database. Supported type: postgresql, mysql, mariadb, mongodb, redis, keydb, dragonfly, clickhouse.	{ type, name?, isPublic?, publicPort?, image?, credentials?, limits? }
databases.get	Details + internal connection URL.	{ uuid }
databases.update	PATCH name, public visibility, image, limits.	{ uuid, patch }
databases.delete	Destroy the database. Volumes kept by default.	{ uuid, confirm } — confirm must equal the db's exact name

3.5 Auth provider tools

Authentication is a first-class capability. An agent cannot spin up arbitrary Coolify services — only vetted auth providers from an allowlist.

Tool	Purpose	Params
auth.list	Auth providers currently deployed in the workspace (classified by Coolify's service_type).	—
auth.create	Provision one of the allowed providers.	{ provider, name?, description?, instantDeploy? }
auth.delete	Destroy an auth provider. Volumes (user data) kept by default.	{ uuid, confirm } — confirm must equal the service's exact name

Allowed providers (keys passed as provider):

• pocketbase — lightweight (SQLite) auth + data, single container.
• authentik — feature-rich self-hosted IDP.
• keycloak / keycloak-with-postgres — industry-standard OIDC/SAML.
• pocket-id / pocket-id-with-postgresql — passkey-first OIDC.
• logto — dev-first IDP.
• supertokens-with-postgresql — session/auth backend.

Requesting anything outside this list returns 400 with a hint listing the allowed ones, so the agent can self-correct.

3.6 Domain tools (P5.1 — custom apex domains)

Custom apex domains are owned end-to-end by Vibn: the registrar is OpenSRS (Tucows), authoritative DNS is Google Cloud DNS in the Canadian project, and domains are pinned to the workspace that registered them. All four lifecycle steps — search, register, attach, inspect — are agent-callable.

Tool	Purpose	Params
domains.search	Check availability + price for one or more candidate apex domains via OpenSRS. Stateless; does not reserve anything.	{ names: string[], period?: number } — names up to 25, period in years (auto-bumped for quirky TLDs like .ai which requires 2y minimum).
domains.register	Register a domain through OpenSRS. Registers unlocked; locking happens automatically after domains.attach completes. Idempotent per (workspace, domain).	{ domain, period?, whoisPrivacy?, contact, nameservers?, ca?: { cprCategory, legalType } } — ca.* required for .ca.
domains.list	List all domains owned by the workspace with their status, registrar order id, expiry, and DNS provider/zone.	—
domains.get	Full record + last 20 lifecycle events.	{ domain }
domains.attach	Wire a registered domain to a Coolify app (or arbitrary IP/CNAME): create Cloud DNS zone, write A/CNAME rrsets, update registrar-side nameservers, append FQDNs to the Coolify app's domain list. Idempotent; safe to retry.	{ domain, appUuid? | ip? | cname?, subdomains?: string[] (default ["@","www"]), updateRegistrarNs? }

Object storage (GCS via S3-compatible HMAC)

Every workspace gets a Canada-hosted GCS bucket, a dedicated service account, and an HMAC keypair so agent-built apps can use any AWS S3 SDK. The HMAC secret is never returned through the API — it's written directly into Coolify apps via storage.inject_env.

Tool	Purpose	Params
storage.describe	Report the workspace bucket name, region, S3 endpoint, access-key id, and provision status. No secret returned.	—
storage.provision	Idempotently create/reconcile the workspace's GCP service account, JSON keyfile, bucket (vibn-ws-{slug}-{rand}), IAM binding, and HMAC key. Safe to re-run.	—
storage.inject_env	Push STORAGE_* env vars (endpoint, region, bucket, access key id, secret access key, force_path_style) into a Coolify app. The secret is written server-side with is_shown_once=true; it never transits the response body.	{ uuid, prefix? } — prefix defaults to STORAGE_; use S3_ for apps that expect AWS-standard names

The bucket is S3-compatible: point any aws-sdk / @aws-sdk/client-s3 / boto3 at STORAGE_ENDPOINT with force_path_style=true (STORAGE_* env vars are set by storage.inject_env).

Residency note: Cloud DNS is global anycast — configuration is not Canadian-pinned at the storage layer. The workspace-level dns_provider flag (default cloud_dns) will let us swap in CIRA D-Zone for strict Canadian residency without touching the MCP surface.

Billing: Every successful domains.register writes a debit row to vibn_billing_ledger with the OpenSRS order id as ref_id. The vibn_domain_events table keeps an append-only audit of every lifecycle call (register.attempt, register.success, register.failed, attach.success).

Verified end-to-end (2026-04-22) against PROD GCP + OpenSRS sandbox + PROD Coolify (Coolify v4.0.0-beta.473); see vibn-frontend/scripts/smoke-attach-e2e.ts. All 5 sub-systems green.

• ✓ OpenSRS register against Horizon (sandbox) returns order id, response 200.
• ✓ Cloud DNS managed zone created in master-ai-484822 with public anycast NS.
• ✓ A records (@, www) written to the zone.
• ✓ Registrar-side nameserver update accepts Cloud DNS NS values (trailing-dot normalization in lib/opensrs.ts); sandbox returns 480 because its mock registry doesn't know real Google NS hosts, which is expected — live mode talks to real registries that accept any resolvable NS.
• ✓ Unlock → update NS → relock fallback path verified (sandbox-recognized nameservers return 200; the unlock/relock sequence is exercised when the registry returns 405 lock-conflict).
• ✓ Coolify domain-list PATCH adds the apex + www to the application fqdn column and the smoke test re-fetches it to confirm.

Operational gotcha — the destination server must be proxy-enabled. Coolify's update_by_uuid controller accepts domains as a comma-separated list and only maps it onto the model's fqdn column when the destination server's Server::isProxyShouldRun() returns true. That helper requires both proxy.type ∈ {TRAEFIK, CADDY} and is_build_server = false. If either is misconfigured the PATCH returns 200 but the field is silently dropped (Laravel mass-assignment ignores domains because it isn't in $fillable, and the controller never copies it into fqdn). We hit this on coolify-server-mtl (zg4cwgc44ogc08804000gggo), which had proxy=null and is_build_server=true. Fixed by:

UPDATE servers
  SET proxy = jsonb_set(coalesce(proxy,'{}'::jsonb), '{type}', '"TRAEFIK"')
  WHERE uuid = 'zg4cwgc44ogc08804000gggo';
UPDATE server_settings
  SET is_build_server = false
  WHERE server_id = (SELECT id FROM servers WHERE uuid = 'zg4cwgc44ogc08804000gggo');

followed by docker restart coolify to clear Laravel's in-memory config. Sending fqdn directly is not an alternative — the controller's $allowedFields whitelist rejects it with 422 "This field is not allowed."

3.7 Agent-side stdio MCP servers (vibn-agent-runner)

Separate from the control-plane MCP at /api/mcp (which is what external agents call into Vibn), the vibn-agent-runner exposes its own in-house tool surface outward over stdio MCP. This lets Cursor, Claude Desktop, Goose, or any MCP-speaking client drive the same Coolify / Gitea / workspace tooling the Coder/PM/Marketing sub-agents use internally — with the same protected-repo and protected-app guardrails enforced centrally.

Architecture: every tool now has three touch-points backed by one source of truth:

vibn-agent-runner/src/tools/<domain>-api.ts   ← pure, config-agnostic logic + security guards
vibn-agent-runner/src/tools/<domain>.ts       ← thin registerTool() wrappers for the in-process agent loop
vibn-agent-runner/src/mcp/<domain>-server.ts  ← stdio MCP server for external clients

Server	Tools	Required env
vibn-coolify-mcp	7 — list_projects, list_applications, deploy, get_logs, list_all_apps, get_app_status, deploy_app	COOLIFY_API_URL, COOLIFY_API_TOKEN
vibn-gitea-mcp	6 — create/list/close issues, list_repos, list_all_issues, read_repo_file	GITEA_API_URL, GITEA_API_TOKEN, GITEA_USERNAME
vibn-workspace-mcp	8 — read/write/replace/list/find/search_code, execute_command, git_commit_and_push	WORKSPACE_ROOT (+ Gitea creds for git push)
vibn-platform-mcp	7 — save_memory, list_memory, list_skills, get_skill, finalize_prd, get_prd, web_search	SESSION_KEY (optional), Gitea creds (for skills)
vibn-agent-mcp	2 — spawn_agent, get_job_status (dispatches into the runner's HTTP API)	AGENT_RUNNER_URL (defaults to http://localhost:3333)

Run locally with npm run mcp:<name> (or :dev via ts-node) in vibn-agent-runner/. Smoke-test any server with node scripts/smoke-mcp.js <name>. The in-process agent loop still sees the same 28 registered tools — no behavioral regression.

---

4. REST surface

Every MCP tool is also exposed as a plain HTTP endpoint under /api/workspaces/{slug}/…. Agents that prefer curl-style access can use these directly; the shape is identical to the MCP params. Auth is the same bearer header.

---

5. Gitea surface

AI agents never talk to the root Gitea admin token. They use the workspace's dedicated bot user.

5.1 What the bot can do

• Fully own the vibn-{slug} org (added as the org's owner team).
• Read/write every repo in that org via its PAT.
• Push over SSH using the workspace's ed25519 deploy key (same keypair Coolify uses to pull code).
• What it cannot do: touch any other org, the root admin surface, or Gitea's /admin/* endpoints.

5.2 How to get the bot credentials

GET /api/workspaces/{slug}/gitea-credentials
Authorization: Bearer vibn_sk_…

Returns:

{
  "bot": { "username": "mark-bot", "token": "…" },
  "gitea": {
    "apiBase": "https://git.vibnai.com/api/v1",
    "host": "git.vibnai.com",
    "cloneUrlTemplate": "https://mark-bot:{{token}}@git.vibnai.com/vibn-mark/{{repo}}.git",
    "sshRemoteTemplate": "git@git.vibnai.com:vibn-mark/{{repo}}.git",
    "webUrlTemplate": "https://git.vibnai.com/vibn-mark/{{repo}}"
  },
  "workspace": { "slug": "mark", "giteaOrg": "vibn-mark" }
}

The PAT is stored encrypted at rest using AES-256-GCM with the VIBN_SECRETS_KEY server secret; the decrypt step runs only on this endpoint.

5.3 Gitea operations via the standard Gitea API

Once the agent has {bot.token, gitea.apiBase}, it can call any standard Gitea v1 endpoint as the bot, scoped to the workspace org. Common ones:

• POST /orgs/{org}/repos — create a repo.
• PATCH /repos/{org}/{repo} — update repo settings.
• GET /repos/{org}/{repo}/contents/{path} — read files.
• PUT /repos/{org}/{repo}/contents/{path} — write files (commits).
• POST /repos/{org}/{repo}/pulls — open PRs.
• POST /repos/{org}/{repo}/branches — create branches.

---

6. Domain policy

Every app gets an auto-generated domain under the workspace's namespace:

{app-slug}.{workspace-slug}.vibnai.com

For example, creating an app named my-api in workspace mark yields my-api.mark.vibnai.com automatically — no DNS config, no cert work, served by Coolify's wildcard Traefik.

6.1 What agents can do

• Accept the auto-generated domain (default path).
• Replace the domain set via PATCH /apps/{uuid}/domains, provided every entry ends with .{workspace-slug}.vibnai.com.

6.2 What agents cannot do

• Point an app at a domain outside the workspace's namespace. The server rejects this with 403 regardless of DNS state:

  { "error": "Domain evil.com is not allowed; must end with .mark.vibnai.com",
    "hint": "Use my-api.mark.vibnai.com" }
  

This is enforced by isDomainUnderWorkspace() in lib/naming.ts.

6.3 Custom (external) domains

Not exposed to AI agents. A human can still add them through Coolify directly or through a future human-gated UI.

---

7. Safety model

7.1 Tenant enforcement

Every resource-returning helper in lib/coolify.ts runs through ensureResourceInProject(). It:

1. Trusts an explicit project_uuid on the resource if present, else
2. Fetches the project's environment ids via GET /projects/{uuid} and verifies the resource's environment_id is in that set.

A token for mark that tries to read an app in justine's project returns:

{ "error": "Application <uuid> does not belong to project <mark-project-uuid>" }

with HTTP 403. Cross-workspace enumeration and access are not just discouraged — they fail at the helper level.

7.2 Destructive operations

Every delete endpoint requires ?confirm=<exact-resource-name>:

DELETE /apps/{uuid}                → 409 "confirmation required"
DELETE /apps/{uuid}?confirm=wrong  → 409 "confirmation required"
DELETE /apps/{uuid}?confirm=my-api → 200 deleted

This means an agent hallucinating a delete call cannot cost you the resource — it must first know the exact name, which implies it just listed or just created it.

Volumes are kept by default on delete. To also remove volumes, pass ?volumes=delete (apps/dbs) — this is opt-in, per-call, never the default.

7.3 Creation guardrails

• Apps can only be created from repos in the workspace's Gitea org.
• Auth providers can only be created from the allowlist (see §3.5).
• Database flavors are restricted to the 8 Coolify supports.
• Env var keys must match /^[A-Z_][A-Z0-9_]*$/ (no shell-escape tricks).

7.4 Secrets handling

• VIBN_API_KEY is only shown once on mint. Server keeps a sha256 hash.
• Gitea bot PATs are encrypted at rest (AES-256-GCM with VIBN_SECRETS_KEY).
• The SSH private key is held by Coolify, not by Vibn; the public key is pushed to the Gitea bot user's key list. Rotating is a re-provision.
• Agent prompts and Cursor rules include a "treat VIBN_API_KEY like a password — never print or commit it" directive.

---

8. Worked examples

8.1 "Build me a Next.js app with a Postgres and Pocketbase auth"

From the agent's side, using MCP:

// 1. Ensure a repo exists in the workspace org (standard Gitea API,
//    using the bot PAT from gitea.credentials).
POST https://git.vibnai.com/api/v1/orgs/vibn-mark/repos
{ "name": "my-site", "private": true, "auto_init": true }

// 2. Create the Coolify app. Auto-domain my-site.mark.vibnai.com.
{ "tool": "apps.create",
  "params": { "repo": "my-site", "ports": "3000", "instantDeploy": false } }

// 3. Provision a Postgres.
{ "tool": "databases.create",
  "params": { "type": "postgresql", "name": "app-db" } }
// → returns { internalUrl: "postgres://…@<uuid>:5432/postgres" }

// 4. Wire the db URL into the app as an env var.
{ "tool": "apps.envs.upsert",
  "params": { "uuid": "<app-uuid>", "key": "DATABASE_URL",
              "value": "<internalUrl>" } }

// 5. Deploy Pocketbase as the auth layer.
{ "tool": "auth.create",
  "params": { "provider": "pocketbase", "name": "auth" } }

// 6. First real deploy.
{ "tool": "apps.deploy", "params": { "uuid": "<app-uuid>" } }

// 7. Poll.
{ "tool": "apps.deployments", "params": { "uuid": "<app-uuid>" } }
// → [{ uuid, status: "finished" | "in_progress" | "failed" | "queued" }]

The agent hands the user back https://my-site.mark.vibnai.com.

8.2 "Add an api subdomain to my app"

{ "tool": "apps.domains.set",
  "params": {
    "uuid": "<app-uuid>",
    "domains": ["my-site.mark.vibnai.com", "api.mark.vibnai.com"]
  } }

Valid — both end with .mark.vibnai.com. evil.com or my-site.justine.vibnai.com would return 403.

8.3 "Delete the whole thing"

Agent must learn the resource names first (or it'll hit the confirm gate):

// Learn the name.
{ "tool": "apps.get", "params": { "uuid": "<app-uuid>" } }
// → { name: "my-site", ... }

// Delete with matching confirm.
{ "tool": "apps.delete",
  "params": { "uuid": "<app-uuid>", "confirm": "my-site" } }

Wrong confirm returns 409 "Confirmation required".

---

9. Error handling reference

Status	Meaning	What the agent should do
400	Bad request body (invalid JSON, missing required field, invalid type).	Fix the body, retry.
401	No / bad bearer token.	Ask the user to mint a fresh key.
403	Tenant mismatch — resource belongs to another workspace, domain outside workspace namespace, or repo not in workspace org.	Stop. Do not retry with guessed values. Ask the user.
404	Resource not found (app/db/service/repo uuid wrong).	Re-list to find the right uuid.
409	Delete confirmation missing or wrong.	Fetch the resource name first, then retry with confirm=<name>.
422	Coolify validation failure (e.g. malformed domain).	Check the details field.
502	Upstream Coolify/Gitea error.	Retry with backoff.
503	Workspace not fully provisioned yet.	Call POST /provision, then retry.

---

10. Versioning

The MCP descriptor at GET /api/mcp reports a semver version. Tool names are append-only within a major version — agents can cache the tool list safely for the duration of a conversation but should re-fetch on 404.

Current version: 2.2.0.

• 1.x — session-cookie-only MCP, no tenant keys.
• 2.0 — vibn_sk_… keys, workspace-scoped Gitea bot + Coolify project.
• 2.1 — create/update/delete for apps, 8 database flavors, auth provider allowlist, domain policy enforcement, confirm-gated deletes.
• 2.2 — per-workspace GCS object storage (storage.*), compose-aware domain routing, runtime log tailing (apps.logs), in-container command execution (apps.exec), and diagnostic apps.update responses.

---

11. Troubleshooting compose apps

Most real-world app failures fall into a small number of patterns. The recipes below are the canonical diagnostic flow for an agent operating on behalf of a user.

11.1 "Deployment succeeds but the app keeps restarting"

Agents should NOT trust Coolify's deployment status alone. A successful build + healthcheck-pending response usually means the containers came up but the app logic is crashing. Investigate with:

1. apps.logs { uuid, lines: 300 } — look for warnings (empty services indicate containers never ran) and per-service stderr.

2. If the logs show repeated DB errors like relation "xxx" does not exist or pq: no such table, the app skipped its migration step. This is common for Docker Compose apps whose server service only runs migrations on a separate worker command.

3. Run the app's migration CLI via apps.exec, e.g. for Twenty:

   {
     "action": "apps.exec",
     "params": {
       "uuid": "<app-uuid>",
       "service": "server",
       "command": "yarn command:prod database:migrate:prod",
       "timeout_ms": 300000
     }
   }
   

4. Re-check logs — errors should be gone. Then apps.deploy (or just wait for the next restart) and verify the container reports healthy.

11.2 "apps.update returned success but nothing changed"

Check the applied / ignored / rerouted arrays in the response. The most common reroutes:

• fqdn, domains, docker_compose_domains → use apps.domains.set.
• git_repository → use apps.rewire_git (rewrites the clone URL with the workspace's Gitea PAT embedded).
• build_pack — changing this mid-life for an existing app is not supported. Recreate the app.

11.3 "Compose app is up but the domain 502s"

Coolify's API treats compose and single-container apps differently: compose apps use docker_compose_domains (array of {name, domain}), single-container apps use domains (comma-separated string). apps.domains.set handles both, but if you're seeing a 502:

1. apps.domains.list { uuid } — confirm the domain is actually attached to a service (not just the app).
2. apps.exec { uuid, service: "server", command: "nc -vz localhost <port>" } — verify the upstream container is listening.
3. apps.logs { uuid, service: "server", lines: 200 } — look for startup errors like EADDRINUSE or config failures.

11.4 "Healthcheck times out on first deploy"

Docker Compose healthchecks have a start_period grace window. Apps that run long-running migrations on first boot (Twenty, Directus, older Strapi versions) need a start_period that covers the cold start, typically 120–600s.

• Fix at the compose level: edit the repo's docker-compose.yml to set healthcheck.start_period: 300s on the affected service, commit, push, apps.deploy.
• Alternatively, handle migrations out-of-band via apps.exec and let the default healthcheck succeed instantly.

11.5 "I can't tell what's inside the container"

apps.exec is the escape hatch. Useful shell one-liners:

Goal	Command
List running processes	ps -ef
Show env vars	env | sort
Check file exists	ls -la /path/to/file
Test DB connection	nc -vz postgres 5432 or psql $POSTGRES_URL -c 'select 1'
Tail an app's internal log	tail -200 /var/log/app.log
Run a framework CLI	yarn <script>, npm run <script>, python manage.py <cmd>
Inspect filesystem diff vs image	find /app -newer /tmp/marker -type f 2>/dev/null

Output is capped at 1 MB by default (bump with max_bytes). Commands that could exceed the wall-clock timeout should bump timeout_ms (max 600000 = 10 minutes).

11.6 "The agent wants to run something interactively"

It can't. apps.exec is strictly non-interactive: no TTY, no stdin, no session resumption. For migrations and CLI invocations this is the right shape. For genuinely interactive work (a debug shell), the operator needs SSH + docker exec -it directly — outside the platform's AI surface.

12. Where to look in the code

• lib/auth/workspace-auth.ts — requireWorkspacePrincipal, the gate.
• lib/auth/secret-box.ts — AES-256-GCM encryption of Gitea PATs.
• lib/workspaces.ts — ensureWorkspaceProvisioned (the idempotent setup).
• lib/gitea.ts — Gitea client (orgs, users, PATs, SSH keys).
• lib/coolify.ts — Coolify client, tenant helpers, all resource CRUD.
• lib/coolify-ssh.ts — SSH transport for tools that need host-level docker access (apps.logs, apps.exec). Uses a dedicated vibn-logs user on the Coolify host with docker-group membership and no shell.
• lib/coolify-containers.ts — container enumeration + service resolution, shared between logs and exec paths.
• lib/coolify-logs.ts — compose-aware log tailing.
• lib/coolify-exec.ts — one-shot docker exec over SSH with timeout, output caps, and audit logging.
• lib/naming.ts — domain policy, slugify, SSH URL templates.
• lib/ssh-keys.ts — ed25519 keypair generation + OpenSSH formatting.
• app/api/workspaces/[slug]/… — REST surface.
• app/api/mcp/route.ts — MCP dispatcher and tool implementations.
• components/workspace/WorkspaceKeysPanel.tsx — settings UI.
