List tables and views in a database schema.
AI agents call list_tables to retrieve information from Oracle DB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries metadata about tables and views without creating, modifying, deleting, or executing any data changes. It is a straightforward schema browsing operation, consistent with the Read category. The blast radius is minimal—an AI agent cannot cause harm through listing database objects.
From the tool's definition Tool name is 'list_tables' and description states it 'List tables and views in a database schema' — a pure retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List tables and views in a database schema. It is categorised as a Read tool in the Oracle DB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Oracle DB MCP Server MCP server in PolicyLayer and add a rule for list_tables: 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 DB MCP Server. Nothing to install.
list_tables 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 list_tables 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 list_tables. 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.
list_tables is provided by the Oracle DB MCP Server MCP server (titan213/oracle-db-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
