Suggest tables that may be related to the given table based on foreign keys, naming patterns, or shared columns. Returns suggestions with confidence scores and relationship descriptions. Useful for discovering relevant tables when building complex queries.
AI agents call suggestRelatedTables to retrieve information from Oracle Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though suggestRelatedTables only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Register the Oracle Database MCP Server MCP server in PolicyLayer and add a rule for suggestRelatedTables: 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 Database MCP Server. Nothing to install.
suggestRelatedTables 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 suggestRelatedTables 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 suggestRelatedTables. 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.
suggestRelatedTables is provided by the Oracle Database MCP Server MCP server (tannerpace/mcp-oracle-database). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
