Server has 8 tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (browser_navigate, browser_click), which is good. However, descriptions are minimal (10-30 chars), parameter descriptions are sparse or missing, and output schemas are not documented. No error handling guidance, no parameter constraints (enums, ranges), and no indication of idempotency or side effects. The server lacks the depth expected for production use.

• Expand tool descriptions to 100-200 chars. Example: 'browser_navigate: Navigate to a URL in the browser. Use this to load web pages, follow links, or access new domains. Returns the page title and initial content. Fails if the URL is invalid or unreachable.'
• Document output schemas explicitly. Define what browser_screenshot returns (e.g., {type: 'image', mimeType: 'image/png', data: base64}) and what browser_get_html returns (e.g., {type: 'text', mimeType: 'text/html', content: string}).
• Add parameter descriptions for all inputs. E.g., 'selector: CSS selector string (e.g., #button-id, .class-name, button[type=submit]). Must match exactly one element or the tool fails.'
• Add error recovery hints. E.g., 'If navigation fails with timeout, try increasing the timeout parameter or check the URL format. If the page requires authentication, use browser_type to enter credentials first.'
• Mark destructive tools with explicit warnings in descriptions. E.g., 'browser_click: Click an element on the page. WARNING: This modifies page state and may trigger form submissions, navigation, or API calls. Not idempotent, repeated clicks may cause duplicate actions.'
