Implementation Reference
- src/tools/network.ts:66-72 (handler)The handler function that sets the response to include network requests for the selected page, applying pagination (pageSize, pageIdx) and resource type filtering.
handler: async (request, response) => { response.setIncludeNetworkRequests(true, { pageSize: request.params.pageSize, pageIdx: request.params.pageIdx, resourceTypes: request.params.resourceTypes, }); }, - src/tools/network.ts:42-65 (schema)Zod schema defining optional input parameters for pagination and filtering network requests.
schema: { pageSize: z .number() .int() .positive() .optional() .describe( 'Maximum number of requests to return. When omitted, returns all requests.', ), pageIdx: z .number() .int() .min(0) .optional() .describe( 'Page number to return (0-based). When omitted, returns the first page.', ), resourceTypes: z .array(z.enum(FILTERABLE_RESOURCE_TYPES)) .optional() .describe( 'Filter requests to only return requests of the specified resource types. When omitted or empty, returns all requests.', ), }, - src/main.ts:307-320 (registration)Collects tool definitions from all tool modules, including networkTools which exports listNetworkRequests, and registers each with the MCP server via registerTool.
const tools = [ ...Object.values(consoleTools), ...Object.values(emulationTools), ...Object.values(inputTools), ...Object.values(networkTools), ...Object.values(pagesTools), ...Object.values(performanceTools), ...Object.values(screenshotTools), ...Object.values(scriptTools), ...Object.values(snapshotTools), ]; for (const tool of tools) { registerTool(tool as unknown as ToolDefinition); } - src/tools/network.ts:13-33 (helper)Defines the array of filterable Puppeteer ResourceType enums used in the schema for resourceTypes parameter.
const FILTERABLE_RESOURCE_TYPES: readonly [ResourceType, ...ResourceType[]] = [ 'document', 'stylesheet', 'image', 'media', 'font', 'script', 'texttrack', 'xhr', 'fetch', 'prefetch', 'eventsource', 'websocket', 'manifest', 'signedexchange', 'ping', 'cspviolationreport', 'preflight', 'fedcm', 'other', ];
