AI agents call mysql_show_table_status 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 retrieves and queries table metadata status information from a MySQL database with optional filtering. It performs no modifications to data or schema, executes no arbitrary code, and has no destructive effects. It is a read-only operation that returns informational metadata about tables, fitting the 'Read' category.
From the tool's definition Tool name 'mysql_show_table_status' and description '获取表状态信息' (get table status information) indicate retrieval of metadata about table status. Arguments are 'database' (optional, defaults to current connection) and 'like_pattern' (optional pattern matching).
Documented attack patterns abuse exactly the kind of access mysql_show_table_status gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MySQL MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_show_table_status:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_show_table_status": {}
}
}mysql_show_table_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取表状态信息 Args: database: 数据库名称 (可选，默认使用当前连接的数据库) like_pattern: 表名匹配模式 (可选，例如 '%user%') Returns: 表状态信息的JSON字符串. 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_show_table_status: 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_show_table_status 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_show_table_status 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_show_table_status. 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_show_table_status is provided by the MySQL MCP Server MCP server (mangooer/mysql-mcp-server-sse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MySQL MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
