# Fly.io

### Install flyctl and log in

```bash
brew install flyctl   # macOS
fly auth login
```

### Initialize the app

From the repo root:

```bash
fly launch --no-deploy
```

Accept the generated `fly.toml`. Pick a region close to you.

### Set your secrets

```bash
fly secrets set \
  MCP_TRANSPORT=streamable-http \
  MCP_PORT=8080 \
  PARADEX_ENVIRONMENT=prod
```

### Configure and deploy

Confirm the `[[services]]` block in `fly.toml` listens on port `8080` with health check path `/health`:

```toml
[[services]]
  internal_port = 8080
  protocol = "tcp"

  [[services.tcp_checks]]
    grace_period = "10s"
    interval = "30s"
    restart_limit = 0
    timeout = "5s"

  [[services.http_checks]]
    interval = "10s"
    grace_period = "5s"
    method = "GET"
    path = "/health"
    protocol = "http"
    timeout = "2s"
```

Then deploy:

```bash
fly deploy
```

Your endpoint will be `https://<app-name>.fly.dev/mcp`.

### Connect your AI client

Paste the URL into your AI client's MCP settings. See the [Remote MCP quickstart](/agentic-ai-hub/remote-mcp/quickstart#connect-your-ai-client) for client-specific instructions.

Fly.io keeps one VM running by default (no cold starts). Use `fly scale count 0` to pause billing, `fly scale count 1` to resume. `fly logs` streams live logs.

> More setup than Railway or Render, but gives fine-grained control over region, scaling, and resources.
