WHAT IT DOES

What sf_create_custom_metadata_record does on Salesforce Metadata Mcp

RISK

Why sf_create_custom_metadata_record is rated Medium

This tool creates new metadata records (reversible write operation). While it modifies Salesforce configuration that other systems depend on, the creation itself is reversible through deletion. The blast radius is medium because incorrect metadata records could break flows, Apex logic, or formulas org-wide, but the operation is not destructive or financial in nature.

From the tool's definition Tool name contains 'create' and description states 'Creates a record within an existing Custom Metadata Type'. This is a Create operation that generates new configuration data records in Salesforce.
