## Before you call either

### Close API + MCP

1. Connect with `Close-Scope: mcp.read` unless the job needs writes, and `mcp.write_safe` if it only creates
2. Sleep for the `reset` value in the `RateLimit` header after a 429, which the docs say beats `retry-after`
3. Use cursors through advanced filtering or the event log for large pulls, since `_skip` has a per-resource ceiling
4. Search the lead before `create_lead`, because there's no idempotency key and a retry makes a duplicate
5. Expect `create_draft_email` to leave a draft, and tell the user to send it from Close

### HubSpot API + MCP

1. Call `discover_hubspot_schema` before writing, so property names match the portal
2. Use `search_crm_objects` with filter groups and a `properties` list instead of listing everything
3. Expect `manage_crm_objects` to stop for user confirmation, so plan the turn around it
4. Read `policyName` on a 429 to tell a 10-second burst from the daily cap
5. Ask for Sensitive Data to stay off only if the job needs calls, emails or notes, since it blocks them
