Get the CREATE VIEW definition
AI agents call get_view_definition 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 view schema metadata only. It does not execute queries, modify data, delete objects, or trigger external operations. The read-only server context and sibling tools (all query/retrieval-focused: execute_query for SELECTs, get_table_definition, get_procedure_definition, etc.) confirm the read-only design. Confidence is high because the intent is clearly metadata retrieval with no side effects.
From the tool's definition Tool name 'get_view_definition' and description 'Get the CREATE VIEW definition' indicate retrieval of metadata/schema information. Server is explicitly described as 'read-only MCP server for SQL Server database introspection'.
Attacks that exploit this kind of access
Get the CREATE VIEW definition. 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_definition: 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_definition 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_definition 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_definition. 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_definition 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.
