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
