根据错误信息给出只读等价写法或修复建议，不执行写操作
AI agents call fixQuery 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.
fixQuery is a read-only analysis tool that suggests query corrections based on error messages. It explicitly does not execute write operations and does not modify any data. It falls into the Read category as it only retrieves information and provides suggestions for query improvement. The server description also emphasizes 'read-only interaction with SQL databases' and this tool aligns with that security model.
From the tool's definition Tool description states it provides 'read-only equivalent writing method or repair suggestions' and 'does not execute write operations' (根据错误信息给出只读等价写法或修复建议，不执行写操作). The tool analyzes and suggests fixes without performing any data modifications.
Attacks that exploit this kind of access
根据错误信息给出只读等价写法或修复建议，不执行写操作. 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 fixQuery: 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.
fixQuery 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 fixQuery 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 fixQuery. 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.
fixQuery 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.
