test_sp_draft · MSSQL MCP Server MCP: Risk & Policy

WHAT IT DOES

What test_sp_draft does on MSSQL MCP Server

AI agents invoke test_sp_draft to trigger actions in MSSQL MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why test_sp_draft needs a policy

The tool executes a stored procedure draft against a real database. Although described as 'safe' and pre-deployment, it still runs code (a stored procedure) that could have side effects depending on the SP's contents. Execution of arbitrary stored procedures warrants a high severity classification.

From the tool's definition 'Test a draft stored procedure with specified parameters. Execute the draft version safely before deploying.'
