show create table db_name.table_name
AI agents call show_create_table to retrieve information from Alibaba Cloud RDS OpenAPI 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 existing table schema information (the CREATE TABLE definition) without creating, modifying, deleting, or executing any operations. It has no side effects and is purely informational. While the server provides tools for destructive and write operations (create_db_instance, create_db_instance_account), this specific tool is a schema inspection utility, making it a Read operation with low severity.
From the tool's definition The tool is invoked as 'show create table db_name.table_name', which retrieves and displays the CREATE TABLE statement for an existing table. This is a read-only query operation that returns schema metadata without modifying or executing any data operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and Alibaba Cloud RDS OpenAPI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for show_create_table:
{
"version": "1",
"default": "deny",
"tools": {
"show_create_table": {}
}
}show_create_table is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

show create table db_name.table_name. It is categorised as a Read tool in the Alibaba Cloud RDS OpenAPI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Alibaba Cloud RDS OpenAPI MCP Server MCP server in PolicyLayer and add a rule for show_create_table: 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 Alibaba Cloud RDS OpenAPI MCP Server. Nothing to install.
show_create_table 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 show_create_table 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 show_create_table. 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.
show_create_table is provided by the Alibaba Cloud RDS OpenAPI MCP Server MCP server (aliyun/alibabacloud-rds-openapi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
