Jack Cloud

# Jack Cloud — Deploy Anything from the Terminal

Jack deploys Cloudflare Workers projects in one command. Create an API, add a database, ship it live — all from the terminal.

Install

```bash npm i -g @getjack/jack jack login ```

External Endpoints

| Endpoint | Data Sent | Purpose | |----------|-----------|---------| | `auth.getjack.org` | OAuth tokens (GitHub/Google via WorkOS) | Authentication | | `control.getjack.org` | Project metadata, source code during deploy | Project management and deployments |

Security & Privacy

• `jack login` authenticates via browser OAuth (GitHub/Google via WorkOS). Auth token stored at `~/.config/jack/auth.json`
• No environment variables required — authentication is interactive
• Source code is uploaded during `jack ship` and deployed to Cloudflare Workers via Jack Cloud
• Project metadata (name, slug, deploy history) is stored on Jack Cloud
• No telemetry is sent without user consent (`jack telemetry` to configure)
• npm package: @getjack/jack — open source CLI

MCP Tools

If your agent has `mcp__jack__*` tools available, prefer those over CLI commands. They return structured JSON and are tracked automatically. The CLI equivalents are noted below for agents without MCP.

---

Create & Deploy a Project

```bash jack new my-api ```

This creates a project from a template, deploys it, and prints the live URL.

Pick a template when prompted (or pass `--template`):

| Template | What you get | |----------|-------------| | `api` | Hono API with example routes | | `hello` | Minimal hello-world starter | | `miniapp` | Full-stack app with frontend | | `ai-chat` | AI chat app with streaming | | `nextjs` | Next.js full-stack app |

Run `jack new` to see all available templates.

MCP: `mcp__jack__create_project` with `name` and `template` params.

After creation, your project is live at `https://<slug>.runjack.xyz`.

---

Deploy Changes

After editing code, push changes live:

```bash jack ship ```

For machine-readable output (useful in scripts and agents):

```bash jack ship --json ```

Builds the project and deploys to production. Takes a few seconds.

MCP: `mcp__jack__deploy_project`

---

Check Status

```bash jack info ```

Shows: live URL, last deploy time, attached services (databases, storage, etc.).

MCP: `mcp__jack__get_project_status`

---

Database (D1)

```bash jack services db create # Add D1 database (auto-configures wrangler.jsonc) jack db execute "SELECT * FROM users" # Query data jack db execute --json "SELECT ..." # JSON output jack db execute --write "INSERT INTO users (name, email) VALUES ('Alice', 'alice@example.com')" jack db execute --write "CREATE TABLE posts (id INTEGER PRIMARY KEY, title TEXT, body TEXT, created_at TEXT DEFAULT CURRENT_TIMESTAMP)" jack db execute "SELECT name FROM sqlite_master WHERE type='table'" # View schema jack db execute "PRAGMA table_info(users)" ```

After schema changes, redeploy with `jack ship`.

MCP: `mcp__jack__create_database`, `mcp__jack__execute_sql` (set `allow_write: true` for writes; DROP/TRUNCATE blocked by default).

---

Logs

Stream production logs to debug issues:

```bash jack logs ```

Shows real-time request/response logs. Press Ctrl+C to stop.

MCP: `mcp__jack__tail_logs` with `duration_ms` and `max_events` params for a bounded sample.

---

Common Workflow: API with Database

```bash # 1. Create project jack new my-api --template api

# 2. Add database jack services db create

# 3. Create tables jack db execute --write "CREATE TABLE items (id INTEGER PRIMARY KEY, name TEXT, created_at TEXT DEFAULT CURRENT_TIMESTAMP)"

# 4. Edit src/index.ts — add routes that query the DB # Access DB via: c.env.DB (the D1 binding)

# 5. Deploy jack ship

# 6. Verify curl https://my-api.runjack.xyz/api/items ```

---

Secrets

Store API keys and sensitive values:

```bash # Set a secret (prompts for value) jack secrets set STRIPE_SECRET_KEY

# Set multiple jack secrets set API_KEY WEBHOOK_SECRET

# List secrets (names only, values hidden) jack secrets list ```

Secrets are available in your worker as `c.env.SECRET_NAME`. Redeploy after adding secrets:

```bash jack ship ```

---

Project Structure

``` my-project/ ├── src/ │ └── index.ts # Worker entry point ├── wrangler.jsonc # Config: bindings, routes, compatibility ├── package.json └── .jack/ └── project.json # Links to Jack Cloud ```

• `wrangler.jsonc` defines D1 bindings, environment vars, compatibility flags
• `.jack/project.json` links the local directory to your Jack Cloud project
• `src/index.ts` is the main entry point — typically a Hono app

---

Advanced Services

Storage (R2)

```bash jack services storage create # Create R2 bucket jack services storage list # List buckets jack services storage info # Bucket details ```

Access in worker via `c.env.BUCKET` binding. Use for file uploads, images, assets.

MCP: `mcp__jack__create_storage_bucket`, `mcp__jack__list_storage_buckets`, `mcp__jack__get_storage_info`

Vector Search (Vectorize)

```bash jack services vectorize create # Create index (768 dims, cosine) jack services vectorize create --dimensions 1536 # Custom dimensions jack services vectorize list jack services vectorize info ```

Access via `c.env.VECTORIZE_INDEX` binding. Use for semantic search, RAG, embeddings.

MCP: `mcp__jack__create_vectorize_index`, `mcp__jack__list_vectorize_indexes`, `mcp__jack__get_vectorize_info`

Cron Scheduling

```bash jack services cron create "*/15 * * * *" # Every 15 minutes jack services cron create "0 * * * *" # Every hour jack services cron list jack services cron test "0 9 * * MON" # Validate + show next runs ```

Your worker needs a `scheduled()` handler or `POST /__scheduled` route.

MCP: `mcp__jack__create_cron`, `mcp__jack__list_crons`, `mcp__jack__test_cron`

Custom Domains

```bash jack domain connect app.example.com # Reserve domain jack domain assign app.example.com # Assign to current project jack domain unassign app.example.com # Unassign jack domain disconnect app.example.com # Fully remove ```

Follow the DNS instructions printed after `assign`. Typically add a CNAME record.

---

List Projects

```bash jack ls # List all your projects jack info my-api # Details for a specific project jack open my-api # Open in browser ```

MCP: `mcp__jack__list_projects` with optional `filter` (all, local, deployed, cloud).

---

Troubleshooting

| Problem | Fix | |---------|-----| | "Not authenticated" | Run `jack login` | | "No wrangler config found" | Run from a jack project directory | | "Database not found" | Run `jack services db create` | | Deploy fails | Check `jack logs` for errors, fix code, `jack ship` again | | Need to start over | `jack new` creates a fresh project |
