Fetch a sample of rows from a table (default: 10 rows).
AI agents call get_table_sample to retrieve information from Oracle Sqlplus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves sample data from a table for inspection purposes only. It performs no writes, deletions, or execution of arbitrary code. The blast radius of misuse is minimal—an attacker could only read existing data they have database access to, which is a standard read operation. The severity is low because data exposure depends on what data exists in the table and existing access controls.
From the tool's definition Tool name 'get_table_sample' and description 'Fetch a sample of rows from a table' indicate a retrieval operation with no modification or side effects. The action is purely querying data.
Attacks that exploit this kind of access
Fetch a sample of rows from a table (default: 10 rows). It is categorised as a Read tool in the Oracle Sqlplus MCP Server, which means it retrieves data without modifying state.
Register the Oracle Sqlplus MCP server in PolicyLayer and add a rule for get_table_sample: 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 Sqlplus. Nothing to install.
get_table_sample 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 get_table_sample 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 get_table_sample. 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.
get_table_sample is provided by the Oracle Sqlplus MCP server (sagar1012/oracle-sqlplus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
