Implementation Reference
- index.ts:232-251 (handler)The handler logic for the puppeteer_fill tool. Waits for the selector, types the value into the input field, and returns a success or error message.case "puppeteer_fill": try { await page.waitForSelector(args.selector); await page.type(args.selector, args.value); return { content: [{ type: "text", text: `Filled ${args.selector} with: ${args.value}`, }], isError: false, }; } catch (error) { return { content: [{ type: "text", text: `Failed to fill ${args.selector}: ${(error as Error).message}`, }], isError: true, }; }
- index.ts:55-66 (schema)Input schema definition for the puppeteer_fill tool, specifying selector and value parameters.{ name: "puppeteer_fill", description: "Fill out an input field", inputSchema: { type: "object", properties: { selector: { type: "string", description: "CSS selector for input field" }, value: { type: "string", description: "Value to fill" }, }, required: ["selector", "value"], }, },
- index.ts:410-412 (registration)Registration of the tools list handler, which exposes the puppeteer_fill tool via the TOOLS array.server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: TOOLS, }));
- index.ts:414-416 (registration)Registration of the call tool handler, which dispatches to the specific puppeteer_fill implementation in handleToolCall.server.setRequestHandler(CallToolRequestSchema, async (request) => handleToolCall(request.params.name, request.params.arguments ?? {}) );
