## 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

### Streak API + MCP

1. Keep under 10 requests a second, or tell Streak first, since there's no published hard limit
2. Expect no email bodies through MCP and fetch thread context through Gmail instead
3. Send the API key as the Basic auth username with an empty password
4. Check the plan before relying on webhooks, which start at Pro+
5. Handle a 410 as an API version that's no longer supported
