salesforce-mcp-three-org-connections-production-fullcopy-marketing-cloud

The Salesforce MCP server maintains three distinct OAuth sessions: production (runwal.my.salesforce.com), fullcopy sandbox (aliased as ‘sandbox’ in org_configs), and Marketing Cloud (separate tenant). The sandbox alias is a pointer to fullcopy — not a separate connection. Deployment lifecycle always goes fullcopy first, then production. health endpoint confirms connection_count: 3, oauth_sessions: 3.
