Converts recorded or described browser interactions (clicks, form fills, navigation, assertions) into executable Playwright test code by parsing interaction sequences and mapping them to Playwright API calls. Uses an MCP server architecture to expose test generation as a tool callable from LLM clients (Claude, Cursor), enabling real-time test scaffolding without leaving the editor. Generates syntactically valid TypeScript/JavaScript test files with proper page object patterns and selectors.
Unique: Exposes test generation as an MCP tool callable directly from LLM-powered IDEs (Cursor, Claude), enabling in-editor test scaffolding without context switching. Integrates Playwright's native API surface directly into code generation prompts, ensuring generated tests use idiomatic Playwright patterns rather than generic test templates.
vs alternatives: Unlike Playwright Inspector (manual recording) or generic test generators, this MCP server enables LLM-assisted test generation with full IDE integration, allowing developers to describe tests in natural language and receive Playwright code instantly.
Registers test generation capabilities as MCP tools (function definitions with JSON schemas) that LLM clients can discover and invoke. Implements the MCP protocol to expose structured endpoints for test generation, selector extraction, and assertion building, allowing Claude or Cursor to call these tools with typed arguments and receive test code as structured responses. Handles schema validation, error propagation, and response formatting according to MCP specification.
Unique: Implements full MCP protocol compliance for test generation, including schema-based tool registration, typed argument validation, and streaming response support. Enables bidirectional communication between LLM clients and Playwright test generation logic without custom API wrappers.
vs alternatives: Provides native MCP integration vs. REST API wrappers, eliminating HTTP overhead and enabling direct LLM tool invocation with schema validation at the protocol level.
Analyzes DOM elements and generates robust CSS selectors, XPath expressions, or Playwright locators (using getByRole, getByLabel, etc.) for test interactions. Uses heuristics to prefer semantic selectors (role-based, label-based) over fragile ID/class selectors, and generates fallback selectors for resilience. Integrates with Playwright's locator API to produce idiomatic selector code that survives minor DOM changes.
Unique: Prioritizes Playwright's semantic locator API (getByRole, getByLabel, getByPlaceholder) over fragile CSS/XPath, generating accessibility-first selectors that align with modern testing best practices. Includes heuristic fallback chains to handle edge cases without manual intervention.
vs alternatives: Generates more maintainable selectors than generic selector generators by leveraging Playwright's semantic locator API and ARIA attributes, reducing test brittleness compared to ID/class-based selectors.
Generates Playwright assertion code (expect() chains) based on described or inferred test conditions, such as element visibility, text content, URL changes, or network requests. Maps natural language assertions ('the button should be disabled', 'the page should show a success message') to idiomatic Playwright expect() syntax with proper matchers (toBeVisible, toContainText, toHaveURL). Supports both synchronous assertions and async wait conditions with configurable timeouts.
Unique: Maps natural language test conditions directly to Playwright's expect() API with semantic understanding of common assertion patterns (visibility, text, URL, network). Generates assertions with appropriate async handling and timeout configuration based on assertion type.
vs alternatives: Generates idiomatic Playwright assertions vs. generic test assertion templates, ensuring generated code follows Playwright best practices and integrates seamlessly with existing test suites.
Generates page object model (POM) class structures for organizing test code, mapping page elements to reusable methods, and encapsulating selectors and interactions.

Unique: Generates strongly-typed page object classes with method signatures matching Playwright's async API, enabling IDE autocomplete and type checking for page interactions. Includes factory patterns and inheritance support for component reuse.
vs alternatives: Produces maintainable, typed page objects vs. inline selectors scattered across tests, reducing duplication and improving test readability through encapsulation.
Generates complete test suite files with proper setup/teardown hooks (beforeEach, afterEach, beforeAll, afterAll), test structure, and browser context management. Creates test files with Playwright's test runner integration, including fixture definitions, page object imports, and assertion chains. Handles test organization (describe blocks, test naming) and generates configuration for parallel execution, retries, and reporting.
Unique: Generates complete, runnable test files with Playwright test runner integration, including proper fixture definitions, async/await handling, and test organization. Produces files that can be executed immediately without manual boilerplate.
vs alternatives: Generates executable test files vs. code snippets, reducing setup time and ensuring generated tests follow Playwright test runner conventions.
Translates natural language test descriptions (e.g., 'user logs in with valid credentials and sees dashboard') into executable Playwright test code by parsing intent, identifying page interactions, and mapping them to Playwright API calls. Uses LLM context from the MCP client to understand application-specific terminology and generates contextually appropriate test code. Supports multi-step scenarios with branching logic and error handling.
Unique: Leverages LLM reasoning (from MCP client) to understand natural language test descriptions and generate contextually appropriate Playwright code, enabling non-developers to author tests. Integrates application context from the LLM client to produce accurate selectors and interactions.
vs alternatives: Enables natural language test authoring vs. manual code writing, lowering barriers for non-technical team members while maintaining executable Playwright code.
Integrates with Cursor IDE as an MCP server, enabling inline test generation through Cursor's command palette and context menu.

Supports Cursor's inline editing and code insertion features, enabling tests to be generated and inserted into the current file or new test files.
Unique: Provides native Cursor IDE integration via MCP, enabling test generation directly in the editor through command palette and context menu. Eliminates context switching by generating tests inline with full access to code context.
vs alternatives: Offers in-editor test generation vs. external tools or web interfaces, improving developer workflow and reducing friction in test authoring.
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.
