salesforce-mcp-three-orgs-production-fullcopy-marketing-cloud

The Salesforce MCP server maintains 3 distinct OAuth connections: production (runwal.my.salesforce.com), fullcopy sandbox (also aliased as ‘sandbox’ in org_configs), and Marketing Cloud (separate SFMC tenant). Health endpoint returns connection_count: 3 and oauth_sessions: 3. The ‘sandbox’ alias is a pointer to ‘fullcopy’ — same connection, not a 4th org.
