## Verdicts

**Copper API.** Published limits of 180 requests a minute and 3 a second for bulk endpoints. No official MCP server, OpenAPI spec or llms.txt.

**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

### Copper API

1. Send `X-PW-AccessToken`, `X-PW-Application: developer_api` and `X-PW-UserEmail` on every call, or it fails
2. Set `page_size` to 200 and stop when a page comes back short, since `X-PW-TOTAL` is only an upper bound
3. Back off on 429 on your own clock, since no Retry-After is documented
4. Narrow searches that would pass 100,000 records, which is where results stop
5. Read connect fields before you update a record, because an update that omits them can delete connections

### 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
