列出所有数据库表
AI agents call list_all_tables to retrieve information from SP Database 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 lists database table information, which is a read-only operation with no side effects. It falls squarely under the Read category. Severity is low because exposing table names and basic schema information carries minimal risk—it is reconnaissance-level data that does not directly compromise data confidentiality or integrity without further actions.
From the tool's definition Tool name 'list_all_tables' and description '列出所有数据库表' (lists all database tables) indicate a query/retrieval operation that returns metadata about database schema without modifying any data.

Register the SP Database MCP Server MCP server in PolicyLayer and add a rule for list_all_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 SP Database MCP Server. Nothing to install.
list_all_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_all_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_all_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_all_tables is provided by the SP Database MCP Server MCP server (jjvvv/sp-enterprise-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
