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

// WHEN AI AGENTS USE THIS TOOL

AI agents call get-capture-results to retrieve information from Whistle 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.

// WHY ENFORCE A POLICY ON GET-CAPTURE-RESULTS

Even though get-capture-results 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.

// RECOMMENDED POLICY

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

What does the get-capture-results tool do? +

获取当前抓包结果并保存为JSON文件，支持过滤. It is categorised as a Read tool in the Whistle MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get-capture-results? +

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

What risk level is get-capture-results? +

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

Can I rate-limit get-capture-results? +

Yes. Add a rate_limit block to the get-capture-results 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 get-capture-results completely? +

Set action: deny in the Intercept policy for get-capture-results. 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 get-capture-results? +

get-capture-results is provided by the Whistle MCP server (whistle-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
