vs alternatives: More sophisticated than single-page Playwright wrappers; enables complex multi-page workflows that would require multiple browser instances in simpler solutions, reducing resource overhead.
Provides tools for locating and interacting with DOM elements using CSS selectors, XPath expressions, and Playwright's built-in locator API. Supports click, type, fill, hover, and other interaction primitives with automatic waiting for element visibility/stability. Implements selector validation and error handling to provide meaningful feedback when elements are not found.
Unique: Wraps Playwright's locator API with MCP tool definitions, exposing both CSS and XPath selector support with automatic waiting and error handling. Provides structured feedback on element interaction success/failure.
vs alternatives: More reliable than regex-based selector matching; uses Playwright's native waiting mechanisms to handle dynamic content and timing issues that simpler selector tools struggle with.
Extracts page content as plain text, HTML, or structured data using Playwright's page evaluation APIs. Supports full-page text extraction, targeted element text retrieval, and custom JavaScript execution for complex data extraction. Returns content with optional formatting preservation and metadata about extracted elements.
Unique: Combines Playwright's page evaluation with MCP tool definitions to expose both simple text extraction and custom JavaScript-based data extraction. Supports both full-page and targeted element extraction with flexible output formats.
vs alternatives: More flexible than static HTML parsing tools; handles JavaScript-rendered content and supports custom extraction logic without requiring separate scraping frameworks.
Captures full-page or element-specific screenshots as base64-encoded images, enabling visual verification of page state and debugging of visual issues. Supports viewport-specific screenshots, full-page scrolling captures, and element bounding box screenshots. Returns images in PNG format with optional metadata about capture dimensions and timing.
Unique: Exposes Playwright's screenshot API through MCP with support for full-page, viewport, and element-specific captures. Returns base64-encoded images compatible with Claude's vision capabilities for visual analysis.
vs alternatives: Integrates screenshot capture directly into MCP workflows, allowing Claude to see page state visually and make decisions based on rendered appearance rather than just DOM structure.

Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
