AI agents call miniapp_graph_stats to retrieve information from Wechat Miniapp Engineering without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis and reporting on code structure and metrics. It retrieves and presents information about a Mini Program's dependency graph and routing patterns for inspection purposes only. There is no indication of data modification, code execution, deletion, or external operations. The 'risk alerts' (风险提示) mentioned are warnings generated by the analysis itself, not actions taken by the tool.
From the tool's definition Tool outputs statistics and analysis of Mini Program code graphs: node/edge types, route chains, important nodes and risk alerts. The description indicates it 'outputs' (输出) metrics and visual data without modifying anything.

Register the Wechat Miniapp Engineering MCP server in PolicyLayer and add a rule for miniapp_graph_stats: 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 Wechat Miniapp Engineering. Nothing to install.
miniapp_graph_stats 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 miniapp_graph_stats 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 miniapp_graph_stats. 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.
miniapp_graph_stats is provided by the Wechat Miniapp Engineering MCP server (lychee20000105/wechat-miniapp-engineering-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
