获取指定表的结构信息
AI agents call get_table_structure to retrieve information from Jewei MSSQL 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 table schemas (columns, data types, constraints, etc.) without querying data or modifying anything. It is a read-only introspection operation with minimal blast radius—the worst outcome is information disclosure about database structure, which does not enable data theft or system compromise on its own.
From the tool's definition Tool name 'get_table_structure' and description indicating it retrieves structure information ('获取指定表的结构信息' = 'get specified table structure information') about database tables with no mutation capability.

获取指定表的结构信息. It is categorised as a Read tool in the Jewei MSSQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jewei MSSQL 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 Jewei MSSQL 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 Jewei MSSQL MCP Server MCP server (jeweis/jewei-mssql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
