overview_by_c

获取直营城市C端行为数据数据指标报表 生成Excel文件

Part of the Yjzf MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call overview_by_c to retrieve information from Yjzf without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though overview_by_c only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.
