## Before you call it

1. Call `wait_for_call` (it waits up to 45 seconds) instead of polling `get_call_log`
2. Send destructive MCP tools a second time with the confirmation argument
3. Space calls to the same number at least 10 seconds apart or expect a 429
4. Budget $0.015 for every outbound attempt, including ones that never connect
5. Run `validate_pathway` before saving a pathway graph

## Connect

```bash
curl -X POST https://api.bland.ai/v1/calls -H "Authorization: $BLAND_API_KEY" \
  -H "content-type: application/json" \
  -d '{"phone_number":"+15551234567","task":"Confirm tomorrow 3pm appointment and ask if they need to reschedule."}'
```

```bash
claude mcp add --transport http bland https://api.bland.ai/v1/mcp --header "Authorization: Bearer $BLAND_API_KEY"
