基于 EXPLAIN 与规则给出优化建议（只读，不执行）
AI agents call optimizeQuery to retrieve information from SQL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes query execution plans and provides optimization suggestions without executing queries or modifying data. It returns informational analysis based on EXPLAIN output and heuristic rules, making it a pure read operation with no destructive, modifying, or executable side effects. Consistent with the server's read-only design philosophy.
From the tool's definition Tool name 'optimizeQuery' with description stating '基于 EXPLAIN 与规则给出优化建议（只读，不执行）' which translates to 'Based on EXPLAIN and rules, provide optimization suggestions (read-only, does not execute)'.
Attacks that exploit this kind of access
基于 EXPLAIN 与规则给出优化建议（只读，不执行）. It is categorised as a Read tool in the SQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SQL MCP Server MCP server in PolicyLayer and add a rule for optimizeQuery: 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 MCP Server. Nothing to install.
optimizeQuery 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 optimizeQuery 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 optimizeQuery. 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.
optimizeQuery is provided by the SQL MCP Server MCP server (polarisxb/sql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
