Execute a SELECT query on an Oracle database. Returns results as a formatted table. Only SELECT statements are allowed.
AI agents call execute_query 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.
The tool is restricted to SELECT statements, making it a read-only data retrieval operation with no side effects. Severity is medium because SELECT queries on Oracle databases can expose sensitive data if misused by an AI agent, even though no data is modified.
From the tool's definition 'Execute a SELECT query on an Oracle database. Returns results as a formatted table. Only SELECT statements are allowed.'
Attacks that exploit this kind of access
Execute a SELECT query on an Oracle database. Returns results as a formatted table. Only SELECT statements are allowed. 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 execute_query: 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.
execute_query 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 execute_query 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 execute_query. 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.
execute_query 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.
