callPageMethod

调用当前页面实例上定义的页面方法(如 onLoad、onShow、自定义方法等)。可用于触发页面生命周期或执行页面业务逻辑。

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

AI agents call callPageMethod to retrieve information from Wechat Devtools 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 callPageMethod 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.

What does the callPageMethod tool do? +

调用当前页面实例上定义的页面方法(如 onLoad、onShow、自定义方法等)。可用于触发页面生命周期或执行页面业务逻辑。. It is categorised as a Read tool in the Wechat Devtools MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on callPageMethod? +

Add a rule in your Intercept YAML policy under the tools section for callPageMethod. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Wechat Devtools MCP server.

What risk level is callPageMethod? +

callPageMethod is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit callPageMethod? +

Yes. Add a rate_limit block to the callPageMethod rule in your Intercept 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.

How do I block callPageMethod completely? +

Set action: deny in the Intercept policy for callPageMethod. 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.

What MCP server provides callPageMethod? +

callPageMethod is provided by the Wechat Devtools MCP server (wechat-devtools-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
