获取指定数据库的表列表
AI agents call list-tables to retrieve information from Superset 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 data retrieval only—it lists available tables in a database without creating, modifying, executing, or deleting anything. It has minimal blast radius; misuse would only expose metadata about database structure.
From the tool's definition Tool name is 'list-tables' and description indicates it retrieves a table list from a specified database ('获取指定数据库的表列表' translates to 'get table list of specified database'). This is a read-only query operation with no modification or execution capability.

Yes. Add a rate_limit block to the 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 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.
