Execute a SELECT query on the SQL Server database with enforced pagination. Only SELECT queries are allowed - DDL and DML operations (CREATE, ALTER, DROP, INSERT, UPDATE, DELETE, etc.) are rejected.
AI agents call query_data 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.
The tool only permits SELECT queries and explicitly rejects all DDL/DML operations, making it a read-only data retrieval tool. Severity is medium because arbitrary SELECT queries could expose sensitive data across any table in the database, even though no modifications are possible.
From the tool's definition Execute a SELECT query on the SQL Server database with enforced pagination. Only SELECT queries are allowed - DDL and DML operations (CREATE, ALTER, DROP, INSERT, UPDATE, DELETE, etc.) are rejected.

Execute a SELECT query on the SQL Server database with enforced pagination. Only SELECT queries are allowed - DDL and DML operations (CREATE, ALTER, DROP, INSERT, UPDATE, DELETE, etc.) are rejected. 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 query_data: 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.
query_data 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 query_data 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 query_data. 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.
query_data 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.
