## Verdicts

**Close API + MCP.** Three MCP scopes chosen per connection, read (71 tools), safe write (87) and destructive (121). 121 MCP tools, and even the read scope loads 71.

**Salesforce API + MCP.** Per-user OAuth 2.0 with PKCE and only `mcp_api` and `refresh_token` scopes. No hosted MCP changelog yet.

## 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

### Salesforce API + MCP

1. Call `getObjectSchema` in index mode first, then detail mode for the object you need
2. Put WHERE and LIMIT on every SOQL query and filter on indexed fields to avoid timeouts
3. Ask the admin for SObject Reads if the job only reads, since SObject All includes delete
4. Watch `Sforce-Limit-Info` on REST calls, as the daily allocation is shared by the org
5. Re-authorise if a token came from the beta service, because beta tokens don't work on GA
