Select data from a table with optional filtering and pagination
AI agents call mysql_select_data to retrieve information from MySQL 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 SELECT operations to retrieve data from MySQL tables. It supports filtering and pagination but does not modify, delete, or create any data. It is a pure read operation with minimal blast radius if misused, though large queries could expose sensitive data.
From the tool's definition 'Select data from a table with optional filtering and pagination' — read-only query with no side effects
Attacks that exploit this kind of access
Select data from a table with optional filtering and pagination. It is categorised as a Read tool in the MySQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MySQL MCP Server MCP server in PolicyLayer and add a rule for mysql_select_data: 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 MySQL MCP Server. Nothing to install.
mysql_select_data 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 mysql_select_data 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 mysql_select_data. 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.
mysql_select_data is provided by the MySQL MCP Server MCP server (lakshya-saini/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
