salesforce-mcp-three-org-architecture-production-fullcopy-marketing-cloud
The Salesforce MCP server connects to exactly 3 distinct orgs: (1) ‘production’ — core Sales/Service Cloud org, (2) ‘fullcopy’ (alias: ‘sandbox’) — full copy sandbox for development/testing, (3) Marketing Cloud — separate MC tenant with its own OAuth session. The ‘sandbox’ alias is just a pointer to ‘fullcopy’, not a separate connection. Health endpoint confirms connection_count: 3, oauth_sessions: 3.
