获取指定表的结构信息
AI agents call get_table_structure 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 retrieves metadata about a table's structure (columns, types, constraints, etc.) without executing queries, modifying data, or triggering side effects. It is purely informational—a schema inspection capability, which is a safe read operation. The sibling tools (execute, execute_many, query, transaction) suggest this server supports dangerous operations, but this specific tool is limited to introspection.
From the tool's definition Tool name 'get_table_structure' and description '获取指定表的结构信息' (retrieve structure information of specified table) indicate data retrieval without modification.
Attacks that exploit this kind of access
获取指定表的结构信息. 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_table_structure: 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_table_structure 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_table_structure 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_table_structure. 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_table_structure 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.
