What sf_create_platform_event does on Salesforce Metadata Mcp
AI agents use sf_create_platform_event to create or update resources in Salesforce Metadata Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Salesforce Metadata Mcp environment.
Why sf_create_platform_event is rated Medium
Creating a Platform Event object is a Write operation—it creates a new, persistent data structure in Salesforce that can be modified or deleted later. While Platform Events enable publish/subscribe communication, the tool itself creates the event definition, not publishing/triggering events.
From the tool's definition Tool name contains 'create' and description explicitly states 'Creates a Platform Event object'. The operation is reversible through standard deletion mechanisms.
