Implementation Reference
- src/tools.ts:722-745 (handler)The handler function that implements the core logic of the 'browser_type' tool. It retrieves the browser instance, locates the target element by selector, and types the provided text using Playwright's page.type() method with optional delay and timeout.
private async type(instanceId: string, selector: string, text: string, options: TypeOptions): Promise<ToolResult> { const instance = this.browserManager.getInstance(instanceId); if (!instance) { return { success: false, error: `Instance ${instanceId} not found` }; } try { const typeOptions: any = {}; if (options.delay) typeOptions.delay = options.delay; if (options.timeout) typeOptions.timeout = options.timeout; await instance.page.type(selector, text, typeOptions); return { success: true, data: { selector, text, typed: true }, instanceId }; } catch (error) { return { success: false, error: `Type failed: ${error instanceof Error ? error.message : error}`, instanceId }; } } - src/tools.ts:205-236 (registration)The tool registration object defining the 'browser_type' tool's name, description, and input schema. This is returned as part of the getTools() array for MCP tool discovery.

export interface TypeOptions { delay?: number; timeout?: number; } - src/tools.ts:541-545 (handler)The switch case dispatcher in executeTools() method that routes calls to the browser_type tool to the specific type() handler.
