Implementation Reference
- index.ts:241-260 (handler)The handler for the 'browsercat_fill' tool. It waits for the specified selector to appear, types the provided value into the input field using Puppeteer's page.type method, and returns success or error message.case "browsercat_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:65-76 (schema)Tool definition including name, description, and input schema for 'browsercat_fill'. Defines required parameters: selector (CSS selector for input) and value (string to fill).{ name: "browsercat_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:421-423 (registration)Registration of all tools (including browsercat_fill) via the ListToolsRequestSchema handler, which returns the TOOLS array containing the tool definitions.server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: TOOLS, }));
- index.ts:425-427 (registration)Registration of the CallToolRequestSchema handler, which dispatches tool calls (including browsercat_fill) to the handleToolCall function based on the tool name.server.setRequestHandler(CallToolRequestSchema, async (request) => handleToolCall(request.params.name, request.params.arguments ?? {}) );
