Get column information for a view
AI agents call get_view_columns to retrieve information from SQL Server MCP 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 view columns—a pure inspection operation with no side effects, data modification, or execution of arbitrary code. It is consistent with the server's read-only design for database exploration.
From the tool's definition Tool name 'get_view_columns' and description 'Get column information for a view' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Get column information for a view. It is categorised as a Read tool in the SQL Server MCP MCP Server, which means it retrieves data without modifying state.
Register the SQL Server MCP server in PolicyLayer and add a rule for get_view_columns: 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 SQL Server MCP. Nothing to install.
get_view_columns 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_view_columns 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_view_columns. 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_view_columns is provided by the SQL Server MCP server (millelog/sql-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
