## Verdicts

**Salesflare.** The REST API has a public Swagger 2.0 file covering 71 operations, with typed filters on every list call and a 30-day trial that needs no card. No rate limit numbers, API changelog, SDK or audit log were found in the reviewed documentation, and API keys carry no documented scopes.

**Streak API + MCP.** MCP server is OAuth only and revocable from account settings. MCP tool list and count not published.

## Before you call either

### Salesflare

1. Send `Authorization: Bearer <API key>` to `https://api.salesflare.com`. A person creates the key in Settings, API keys
2. Set `limit` on every list call. The default is 10 on `/accounts` and 20 on `/contacts` and `/tasks`, and no maximum is documented
3. Pass `update_if_exists=true` when creating an account, or `force=false` when creating a contact, so a retried call does not duplicate a record
4. Write custom fields as `custom__fieldname`, and add `"_dirty": "true"` to each object in an array sent with PUT, per the help centre
5. Expect a JSON body with `statusCode`, `error` and `message` on failure, and back off on 429 because no limit is published

### 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
