AI agents call generate_user_report to retrieve information from Juejin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool generates an analytical report based on existing user data. It reads and analyzes data to produce a report — no data is modified, deleted, or created as a side effect. The output is a read-only analysis document. Severity is low as it only aggregates/presents existing information, though there is slight privacy consideration around user behavior analysis.
From the tool's definition 生成用户分析报告，包含兴趣分析、行为模式和成长建议 (Generate user analysis report, including interest analysis, behavior patterns, and growth suggestions)

生成用户分析报告，包含兴趣分析、行为模式和成长建议. It is categorised as a Read tool in the Juejin MCP Server, which means it retrieves data without modifying state.
Register the Juejin MCP server in PolicyLayer and add a rule for generate_user_report: 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 Juejin. Nothing to install.
generate_user_report 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 generate_user_report 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 generate_user_report. 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.
generate_user_report is provided by the Juejin MCP server (ztxtxwd/juejin-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
