获取所有可用的数据库列表
AI agents call list-databases 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 retrieves/queries information about available databases. It has no side effects, does not execute code, modify data, or delete resources. It is a simple enumeration operation that returns metadata only. The low severity reflects minimal blast radius if misused—an attacker would only gain knowledge of available databases, which is reconnaissance-level information gathering.
From the tool's definition Tool name 'list-databases' and description '获取所有可用的数据库列表' (Chinese: 'Get all available database lists') indicates retrieval of database metadata without modification or execution.
Attacks that exploit this kind of access
获取所有可用的数据库列表. It is categorised as a Read tool in the Superset MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Superset MCP Server MCP server in PolicyLayer and add a rule for list-databases: 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 Superset MCP Server. Nothing to install.
list-databases 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-databases 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-databases. 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-databases is provided by the Superset MCP Server MCP server (liuscraft/superset-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
