anonymous-apex · Salesforce MCP: Risk & Policy

WHAT IT DOES

What anonymous-apex does on Salesforce MCP

AI agents invoke anonymous-apex to trigger actions in Salesforce MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why anonymous-apex needs a policy

This tool allows execution of arbitrary code (Apex scripts) in the Salesforce environment. While not immediately destructive on its own, execution of untrusted or misconfigured Apex code could modify data, trigger unwanted business logic, access sensitive information, or interact with external systems.

From the tool's definition Tool name 'anonymous-apex' and description 'Execute Anonymous Apex' indicate execution of arbitrary Apex code within Salesforce. The description explicitly uses the verb 'Execute' combined with 'Anonymous' (unrestricted code).
