Get the structure/schema of a SQL Server table including column names, data types, and constraints.
AI agents call get_table_structure to retrieve information from Boxtalk Data 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 metadata about table structure without side effects. It does not create, modify, delete, or execute code. It falls squarely into the Read category (schema inspection). Severity is low because exposure of schema metadata is a minor risk compared to data exfiltration or destructive operations, though it could aid reconnaissance in an attack chain.
From the tool's definition Tool retrieves table schema information (column names, data types, constraints) with no mention of modifying, deleting, or executing operations. The description explicitly indicates it 'Get[s] the structure' — a read-only inspection operation.
Attacks that exploit this kind of access
Get the structure/schema of a SQL Server table including column names, data types, and constraints. It is categorised as a Read tool in the Boxtalk Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Boxtalk Data 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 Boxtalk Data 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 Boxtalk Data MCP Server MCP server (parikshitboxtalk/boxtalk-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
