WHAT IT DOES

What sf_create_custom_button does on Salesforce Metadata Mcp

AI agents use sf_create_custom_button 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.

RISK

Why sf_create_custom_button is rated Medium

This tool creates new custom UI elements (buttons/links) on Salesforce objects via the Metadata API. Creation is a reversible write operation (buttons can be deleted/modified later), not an execute action (the tool itself doesn't run the button's code, only creates it).

From the tool's definition Tool description explicitly states 'Creates a custom button' - a write operation that adds new metadata to Salesforce objects.
