While reversible (objects can be deleted), creation of External Objects establishes new data connections and relationships that could expose sensitive external data sources or create unintended data linkages if misconfigured by an AI agent. From the tool's own definition: "Tool creates an External Object (__x) linked to an External Data Source. The description explicitly states it 'Creates' a new metadata artifact that 'appears in related lists' and integrates with Salesforce reporting and lookup infrastructure." ## Use case AI agents use sf_create_external_object 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
