Get sample data from a table
AI agents call mssql_sample_data to retrieve information from Enhanced MCP MSSQL Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves sample rows from a table for inspection purposes. It performs a query without side effects, modifying no data and executing no arbitrary code. The blast radius is limited to information disclosure of existing data, and it operates within the documented read-only scope of the server.
From the tool's definition Tool name 'mssql_sample_data' and description 'Get sample data from a table' indicate a retrieval operation with no modification capability.
Attacks that exploit this kind of access
Get sample data from a table. It is categorised as a Read tool in the Enhanced MCP MSSQL Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced MCP MSSQL Server MCP server in PolicyLayer and add a rule for mssql_sample_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 Enhanced MCP MSSQL Server. Nothing to install.
mssql_sample_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 mssql_sample_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 mssql_sample_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.
mssql_sample_data is provided by the Enhanced MCP MSSQL Server MCP server (michaelyuwh/mcp-mssql-connector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
