[READ-ONLY] Detailed info about an APEX application: pages, shared components (LOVs, auth schemes, templates, build options).
AI agents call apex_describe_application 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 and queries metadata about APEX applications and their components without modifying or executing anything. It is purely informational. Severity is medium (not low) because APEX application metadata can expose sensitive information about application architecture, authentication schemes, build options, and component structure that could inform further attacks, making it valuable reconnaissance for…
From the tool's definition Tool description explicitly states '[READ-ONLY]' and enumerates retrieval operations: 'Detailed info about an APEX application: pages, shared components (LOVs, auth schemes, templates, build options)'.
Attacks that exploit this kind of access
[READ-ONLY] Detailed info about an APEX application: pages, shared components (LOVs, auth schemes, templates, build options). 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_describe_application: 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_describe_application 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_describe_application 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_describe_application. 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_describe_application 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.
