## Before you call it

1. Read secrets by reference (op://vault/item/field) with client.secrets.resolve or resolveAll, and keep the reference, not the value, in config
2. On Teams or personal plans budget for 1,000 reads an hour per token and cache resolved values for the run; a 429 means wait for the hourly window, there's no Retry-After
3. Create the service account with only read_items on one vault and --expires-in set to the job length, since permissions can't be narrowed later
4. Set integrationName and integrationVersion in createClient so the usage report shows which agent read what
5. Don't ask the Environments MCP server for a value. Use it to find the variable name, then load it with op run or the SDK

## Connect

```bash
npm install @1password/sdk   # or: pip install onepassword-sdk
```

```bash
export OP_SERVICE_ACCOUNT_TOKEN="$OP_SERVICE_ACCOUNT_TOKEN"
op read "op://Production/Stripe/api_key"   # 1Password CLI, no REST endpoint for secret reads
```
