vibn-agent-runner/AI_CAPABILITIES.md

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…).	{ 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.domains.list	Current domain set.	{ uuid }
apps.domains.set	Replace the domain set. All entries must end with .{slug}.vibnai.com.	{ uuid, domains: string[] }
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: 2.1.0.

• 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.

---

11. 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/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.
