Format and prettify a SQL query with proper indentation and capitalization.
AI agents call format_sql to retrieve information from Claude MCP Data Engineer Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs read-only text processing on SQL input. It has no database connection, does not execute queries, and cannot modify any data. The worst-case misuse would be reformatting a malicious query before execution by another tool, but the format_sql tool itself is purely transformative with no side effects. This qualifies as Read category with low severity.
From the tool's definition Tool description states 'Format and prettify a SQL query' — this is a text transformation utility that does not execute queries, modify data, or produce side effects. It only reformats existing SQL strings.
Attacks that exploit this kind of access
Format and prettify a SQL query with proper indentation and capitalization. It is categorised as a Read tool in the Claude MCP Data Engineer Server MCP Server, which means it retrieves data without modifying state.
Register the Claude MCP Data Engineer Server MCP server in PolicyLayer and add a rule for format_sql: 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 Claude MCP Data Engineer Server. Nothing to install.
format_sql 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 format_sql 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 format_sql. 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.
format_sql is provided by the Claude MCP Data Engineer Server MCP server (itsnikhile/claude-mcp-data-engineer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
