获取数据库中所有表的信息
AI agents call get_tables 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 queries database schema metadata to list available tables. It performs read-only introspection of database structure without modifying, executing operations on, or deleting data. No side effects occur from calling this tool. While the server supports destructive operations (delete, drop via execute/execute_many), this specific tool is purely informational.
From the tool's definition Tool name 'get_tables' and description '获取数据库中所有表的信息' (retrieve information about all tables in a database) indicate a retrieval operation with no side effects.

获取数据库中所有表的信息. 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 get_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 MySQL MCP Server. Nothing to install.
get_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 get_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 get_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.
get_tables is provided by the MySQL MCP Server MCP server (microsnow/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
