List all tables in the database or a specific database
AI agents call mysql_list_tables to retrieve information from Multi-Database 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 a read-only operation to enumerate database tables. It retrieves information about database structure but does not create, modify, delete, or execute code. While information disclosure could be a minor concern in highly sensitive environments, the blast radius is minimal as it only exposes schema names, not data contents. Classified as Read with low severity.
From the tool's definition Tool name 'mysql_list_tables' and description 'List all tables in the database or a specific database' indicate a query operation that retrieves schema metadata without modifying data or executing arbitrary code.
Attacks that exploit this kind of access
List all tables in the database or a specific database. It is categorised as a Read tool in the Multi-Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for mysql_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 Multi-Database MCP Server. Nothing to install.
mysql_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 mysql_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 mysql_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.
mysql_list_tables is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
