Exposes Playwright browser automation capabilities through the Model Context Protocol, allowing Claude and other MCP-compatible clients to control browser instances via standardized tool calls. Implements MCP server that translates Claude tool invocations into Playwright API calls, managing browser lifecycle, page context, and action execution within a single server process.
Unique: Bridges Playwright's browser automation API directly into Claude's tool-calling system via MCP protocol, eliminating the need for custom REST endpoints or SDK wrapping — Claude can invoke browser actions as first-class tools with native parameter validation
vs alternatives: Tighter integration than Playwright REST API or custom webhook approaches because it uses MCP's standardized schema-based tool registry, enabling Claude to understand and validate browser actions before execution
Manages browser page lifecycle, navigation, and context switching through MCP tools. Handles URL navigation with wait conditions, page creation/closure, and maintains context across multiple pages within a single browser instance. Implements Playwright's page object model with MCP-compatible tool signatures for goto, reload, goBack, and context switching.
Unique: Exposes Playwright's page context model as discrete MCP tools with explicit wait condition parameters, allowing Claude to reason about page load states and manage multiple pages without direct API knowledge
vs alternatives: More explicit than Selenium's implicit waits because it requires Claude to specify wait conditions upfront, reducing flaky automation from race conditions
Manages the MCP server lifecycle including initialization, tool registration, and request handling. Implements the MCP protocol server that exposes Playwright capabilities as tools with JSON schema validation. Handles tool invocation routing, parameter validation, and response serialization. Manages server startup, shutdown, and resource cleanup.
Unique: Implements a full MCP server that bridges Playwright and Claude, handling protocol compliance, schema validation, and resource management — not just a library wrapper but a production-ready server
vs alternatives: More standardized than custom REST APIs because it uses the MCP protocol which Claude natively understands; more efficient than HTTP polling because MCP uses persistent connections
Provides MCP tools for locating DOM elements using CSS selectors, XPath, or Playwright's locator strategies, and performing user interactions (click, type, hover, focus, blur). Implements Playwright's locator API with MCP-compatible parameters, supporting both single-element and multi-element queries with action chaining.
Unique: Wraps Playwright's locator API (which uses intelligent retry logic and auto-waiting) as MCP tools, giving Claude access to Playwright's resilience features like automatic element waiting without explicit polling code
vs alternatives: More resilient than raw Selenium selectors because Playwright's locators automatically retry and wait for elements; more flexible than Cypress because it supports XPath and custom locator strategies
Extracts page content, DOM structure, and text through MCP tools that execute JavaScript in the browser context. Supports full page HTML retrieval, text content extraction, screenshot capture, and arbitrary JavaScript evaluation. Uses Playwright's page.evaluate() and page.content() methods exposed as MCP tools with structured output formatting.
Unique: Exposes Playwright's page.evaluate() as an MCP tool, allowing Claude to execute arbitrary JavaScript in the browser context and receive structured results — more powerful than DOM-only extraction because it can run page-specific logic
vs alternatives: More flexible than static HTML scraping because it executes JavaScript and waits for dynamic content; more secure than exposing raw browser console because execution is sandboxed to page context
Provides specialized MCP tools for automating form interactions including text input, dropdown selection, checkbox toggling, file upload, and form submission. Implements Playwright's fill(), selectOption(), check(), and setInputFiles() methods with MCP-compatible parameters and error handling for form validation.
Unique: Bundles common form interactions (fill, select, check, upload) as discrete MCP tools with validation-aware error handling, allowing Claude to reason about form state and errors without raw DOM manipulation
vs alternatives: More user-centric than raw element clicking because it uses Playwright's high-level fill() and selectOption() methods which handle edge cases like contenteditable divs and custom select components
Simulates keyboard and mouse events through MCP tools that invoke Playwright's keyboard and mouse APIs. Supports key presses, key combinations (Ctrl+C, Shift+Tab), mouse movements, clicks with modifiers, and drag-and-drop operations. Implements event timing and coordination for complex interactions like drag-to-select or keyboard shortcuts.
Unique: Exposes Playwright's keyboard and mouse APIs as discrete MCP tools with modifier key support and drag-and-drop coordination, enabling Claude to simulate complex user interactions without JavaScript event construction
vs alternatives: More reliable than raw JavaScript event dispatch because Playwright's keyboard/mouse APIs account for browser-specific event ordering and timing; more flexible than Selenium because it supports drag-and-drop natively
Provides MCP tools for explicit waiting and synchronization: wait for element visibility, wait for navigation, wait for function conditions, and wait for network idle. Implements Playwright's waitForSelector(), waitForNavigation(), waitForFunction(), and waitForLoadState() with configurable timeouts and polling intervals. Allows Claude to coordinate automation steps with page state changes.
Unique: Exposes Playwright's wait primitives as explicit MCP tools, allowing Claude to reason about and control synchronization points rather than relying on implicit waits or fixed delays
vs alternatives: More explicit than Selenium's implicit waits because Claude must specify what to wait for; more reliable than fixed sleep() calls because it polls for actual state changes

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.
Supabase scores higher at 42/100 vs @executeautomation/playwright-mcp-server at 24/100.
