BrowserStack API
Cloud testing platform API for running automated Selenium, Cypress, and Appium tests across 3,000+ real browsers and devices, plus visual regression and accessibility testing.
Sauce Labs API
Cloud-based test automation platform API for running Selenium, Cypress, Playwright, and Appium tests across real and virtual browsers and devices with detailed analytics.
BrowserStack
BrowserStack's official MCP server that enables agents to programmatically manage and execute test cases, run manual/automated tests on real devices and browsers, debug test failures, and perform accessibility testing through natural language prompts integrated into IDEs like VSCode, Cursor, and Claude Desktop.
Debugg AI
AI-powered browser testing MCP server that automates end-to-end testing by directing an AI agent to navigate and test web applications. Agents receive natural language test descriptions and return pass/fail results with screenshots.
mcp-mock-server
A simple Model Context Protocol (MCP) mock server for developing and testing MCP clients. It exposes configurable mock tools, prompt templates, and mock resources via StreamableHTTP or SSE using a YAML configuration file.
mcp-validator
mcp-validator is a Python testing suite (with reference HTTP/STDIO MCP servers) for validating Model Context Protocol (MCP) server implementations against the MCP specification, including protocol version negotiation and compliance testing for HTTP and STDIO transports. It also includes a framework for testing OAuth 2.1-based authentication for the 2025-06-18 protocol version.
msw-server
msw-server is an npm package intended to support Mock Service Worker (MSW) on the server side, enabling request mocking in Node.js/test environments (e.g., SSR or integration tests) so HTTP calls can be intercepted and served with mock handlers.
pact-stub-server
A Pact stub server that serves mock responses for consumer-driven contract tests (Pact) so a consumer can be tested against predictable provider behaviors without calling the real provider.
redfish-mockup-server
A Redfish mockup server that emulates Redfish (HTTP/JSON) endpoints for testing and development without a physical BMC/device.
verify
A Claude Code plugin (“opslane-verify”) that performs spec-driven verification: it interprets an acceptance-spec document, extracts acceptance criteria, runs one browser automation agent per criterion (Playwright) against a local dev server, then a judge step reviews screenshots/traces to produce pass/fail results with evidence (screenshots and session recordings).
fake-smtp-server
fake-smtp-server provides a local/stub SMTP server that can accept email from applications/tests without actually delivering it to real recipients. Typical usage is capturing inbound SMTP traffic for development, integration testing, and demonstrations.
fake-smtp-server
fake-smtp-server is a test/dummy SMTP server that accepts mail for local development or integration testing without delivering it to a real email provider.
http-test-server
http-test-server appears to be a small HTTP server intended for testing HTTP clients/requests (e.g., exercising status codes, routes, request/response behaviors) rather than providing a production API.
slapd-server-mock
slapd-server-mock is a local/mock LDAP server intended to emulate slapd (OpenLDAP) behavior for testing. It helps integration tests and development environments simulate LDAP operations without relying on a real directory service.
mcp-selenium-server-ai
A Java-based MCP server that performs browser automation for testing by translating natural-language test steps into Selenium WebDriver commands, using an LLM to generate/parameterize the Selenium actions.
tf_grpc_test_server
tf_grpc_test_server is a gRPC test server package intended for use in Terraform-related testing. It provides a controllable gRPC endpoint for validating client behavior and integration without needing real upstream services.
dummy-server
A placeholder/dummy server intended for non-production testing or scaffolding; specific endpoints and behaviors are not provided in the supplied content, so capabilities cannot be verified.
testserver
testserver appears to be a generic/local testing server package, intended for use in development or automated testing environments rather than as a production API.
mockingjay-server
mockingjay-server appears to provide a server component for mocking external HTTP/service interactions (used for test/dummy backends), but no repository README/manifest content was provided here, so its concrete API surface and operational characteristics cannot be verified.
