Analyze stored procedure performance including execution count, CPU time, duration, and logical reads from plan cache.
AI agents call analyze_sp_performance to retrieve information from MSSQL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only diagnostic tool that queries performance statistics from SQL Server's plan cache. It retrieves historical performance data and analysis without side effects, state modification, or execution of dynamic code. The metrics retrieved are pre-computed performance statistics, not live execution, placing it firmly in the Read category.
From the tool's definition The tool analyzes stored procedure performance metrics from plan cache including 'execution count, CPU time, duration, and logical reads'—retrieving performance data without modifying state or executing arbitrary operations.
Attacks that exploit this kind of access
Analyze stored procedure performance including execution count, CPU time, duration, and logical reads from plan cache. It is categorised as a Read tool in the MSSQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MSSQL MCP Server MCP server in PolicyLayer and add a rule for analyze_sp_performance: 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 MSSQL MCP Server. Nothing to install.
analyze_sp_performance 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 analyze_sp_performance 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 analyze_sp_performance. 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.
analyze_sp_performance is provided by the MSSQL MCP Server MCP server (jpcanter/sql-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
