Check Oracle DB and APEX connectivity, version, pool status.
AI agents call oracle_health_check 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 performs read-only health checks and status queries. It retrieves system information (connectivity, version, pool status) without creating, modifying, deleting, or executing any operations. The verb 'check' and the nature of diagnostic operations confirm this is a Read category tool. Severity is low because even if called unnecessarily, it cannot damage data or systems.
From the tool's definition Tool description states it 'Check[s] Oracle DB and APEX connectivity, version, pool status' — purely diagnostic/informational operations with no modification or execution capability.
Attacks that exploit this kind of access
Check Oracle DB and APEX connectivity, version, pool status. 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 oracle_health_check: 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.
oracle_health_check 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 oracle_health_check 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 oracle_health_check. 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.
oracle_health_check 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.
