Playwright MCP demonstration with interactive presentation and live browser demos
This server is a static HTTP file server with embedded test management tools, not a proper MCP server. Tool definitions are inferred from code rather than explicitly registered via MCP protocol. No tool schemas are visible in the source, parameters are documented in comments but not in JSON Schema format. Descriptions exist but are generic (avg ~60 chars). Critical issues: (1) No MCP protocol implementation detected, this is a plain Node.js HTTP server, not an MCP-compliant server. (2) Tool definitions are not formally registered; they exist as JavaScript functions with ad-hoc parameter handling. (3) No input validation, error recovery guidance, or structured output schemas. (4) Security concerns: file write operations (reset-results, test-executor) lack permission checks or audit trails. (5) Parameter descriptions lack type constraints, ranges, or format specifications.
Display test case details in formatted output
One-liner for step execution with automatic state management
Get all test results
Get test case details from JSON
Get result for a specific test
List all available test cases from test-cases.json
Load test cases from test-cases.json file
Reset test results by writing new test results data to test-results.json
Reset test to pending status
Not an MCP server, plain HTTP file server with no MCP protocol implementation. No tool registration, capability negotiation, or protocol handshake.
No input schemas visible in source code. Tools accept parameters but lack JSON Schema definitions with type, required, properties, and constraints.
Destructive operations (reset-results, test-executor with fail/pass actions) lack permission checks, confirmation steps, or audit logging.
Parameter descriptions lack type constraints, ranges, enums, or format specifications. E.g., 'stepNum' has no min/max; 'action' has no enum constraint.

Main test runner that loads and displays test case details with execution instructions
Mark test as failed with step number, reason, and execution data
Mark test as passed with total steps, notes, and execution data
Update test to running status and set currentStep
Quick-start function for agents to begin a test execution
Execute test actions including start, beginStep, completeStep, pass, and fail operations
Update a single test result with status, currentStep, notes, and executionData
No error recovery guidance. HTTP endpoints return generic 500 errors with stack traces instead of actionable error messages that guide LLM retry logic.
