[READ-ONLY] List ORDS RESTful service modules, templates, and handlers defined in the schema.
AI agents call apex_list_rest_services to retrieve information from Oracle APEX MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about REST services without modifying, deleting, or executing anything. It falls squarely in the Read category. However, severity is elevated from 'low' to 'medium' because exposing REST service configurations could reveal sensitive architectural details, authentication mechanisms, endpoints, and business logic patterns that could aid attackers in reconnaissance—though the tool itself…
From the tool's definition Tool name and description indicate [READ-ONLY] listing operation: 'List ORDS RESTful service modules, templates, and handlers'. No modification, deletion, or code execution is performed.
Attacks that exploit this kind of access
[READ-ONLY] List ORDS RESTful service modules, templates, and handlers defined in the schema. It is categorised as a Read tool in the Oracle APEX MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Oracle APEX MCP Server MCP server in PolicyLayer and add a rule for apex_list_rest_services: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Oracle APEX MCP Server. Nothing to install.
apex_list_rest_services is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the apex_list_rest_services rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for apex_list_rest_services. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
apex_list_rest_services is provided by the Oracle APEX MCP Server MCP server (silviosotelo/oracle-apex-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
