Show object dependencies — what an object uses and what depends on it.
AI agents call oracle_dependencies 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 introspection of database object relationships and dependency graphs. It retrieves and displays dependency information without creating, modifying, deleting, or executing any operations. The action is purely informational with no side effects on the database state.
From the tool's definition Tool name 'oracle_dependencies' and description 'Show object dependencies — what an object uses and what depends on it' indicate a query/inspection operation that retrieves metadata about database objects without modifying any data.
Attacks that exploit this kind of access
Show object dependencies — what an object uses and what depends on it. 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_dependencies: 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_dependencies 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_dependencies 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_dependencies. 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_dependencies 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.
