Get detailed information about a specific Apex class including its source code
AI agents call get_apex_class to retrieve information from Salesforce without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata and source code from Salesforce without executing code, modifying data, or triggering side effects. It performs a read-only query operation analogous to fetching configuration or code artifacts.
From the tool's definition Tool name is 'get_apex_class' and description states 'Get detailed information about a specific Apex class including its source code' — the verb 'Get' and use of 'including' indicate retrieval of existing data without modification or execution.

{
"version": "1",
"default": "deny",
"tools": {
"get_apex_class": {}
}
}get_apex_class is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
