List all tables in the current MySQL database.
AI agents call list_mysql_tables to retrieve information from Mysql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves metadata about database structure (table names) without modifying, deleting, or executing any operations. It is purely informational and safe to call multiple times.
From the tool's definition Tool name 'list_mysql_tables' and description 'List all tables in the current MySQL database' indicate a retrieval operation with no side effects. This is a standard schema enumeration query.
Documented attack patterns abuse exactly the kind of access list_mysql_tables gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mysql, and nothing reaches the server without passing your rules. This is the rule we recommend for list_mysql_tables:
{
"version": "1",
"default": "deny",
"tools": {
"list_mysql_tables": {}
}
}list_mysql_tables is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all tables in the current MySQL database. It is categorised as a Read tool in the Mysql MCP Server, which means it retrieves data without modifying state.
Register the Mysql MCP server in PolicyLayer and add a rule for list_mysql_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 Mysql. Nothing to install.
list_mysql_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_mysql_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_mysql_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_mysql_tables is provided by the Mysql MCP server (mukul975/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mysql, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
