Jest is a delightful JavaScript Testing Framework with a focus on simplicity. It works with projects using Babel, TypeScript, Node.js, React, Angular, Vue.js and more.
Why this server?
Supports generating and running tests with the Jest framework.
AlicenseAqualityAmaintenanceAnalyzes code to map behaviors, identify untested gaps, and generate grounded integration tests that actually run.1578917MITWhy this server?
Allows running Jest test suites on BrowserStack's cloud infrastructure for cross-browser and cross-device testing
AlicenseBqualityBmaintenanceBrowserStack's Official MCP Server512,516150AGPL 3.0Why this server?
Detects Jest test framework usage in JavaScript projects and integrates it into test strategy analysis.
AlicenseAqualityAmaintenanceocal-first, read-only MCP server that audits repository test architecture across ten language ecosystems. It returns deterministic evidence-backed findings, blockers, rankings, and repository-native test plans without modifying source files.219141MITWhy this server?
Includes testing support with Jest, allowing for running tests with coverage and in watch mode.
AlicenseBqualityCmaintenanceAn MCP server that provides AI assistants with team analytics capabilities for Cursor editor, allowing them to retrieve team member information, usage metrics, and spending data through natural language queries.33MITWhy this server?

AlicenseAqualityDmaintenanceA Model Context Protocol server that provides tools to find regex pattern positions in files and list allowed directories, enabling text analysis with LSP-like functionality.211MITWhy this server?
Generates test commands for Jest to run only affected tests based on import graph analysis.
AlicenseAqualityDmaintenanceMCP server that analyzes TypeScript/JavaScript codebases via AST parsing and dependency graph tracing to identify affected tests, detect dead code, circular dependencies, and trace import chains, enabling AI agents to run only relevant tests.1549MITWhy this server?
Uses Jest testing framework for comprehensive test suite execution and coverage reporting
AlicenseBqualityDmaintenanceEnables comprehensive color manipulation, conversion between 22+ formats (HEX, RGB, HSL, CMYK, LAB, etc.), palette generation, gradient creation, and accessibility compliance checking. Supports framework-specific outputs for CSS, Swift, Android, Flutter, and Tailwind with high-precision conversions and visualization capabilities.25MITWhy this server?
Allows scaffolding of contract tests for API endpoints using Zod schemas, generating boilerplate code for the Jest testing framework.
AlicenseAqualityDmaintenanceAn MCP server that turns Zod schemas into mocks, violations, and contract tests, enabling AI agents to reason about API contracts without manually crafting payloads.1050MITWhy this server?
Supports proper TypeScript typing for Jest testing framework including SpyInstance, mock functions, and test utilities to create accurate test mocks and assertions.
AlicenseBqualityDmaintenanceProvides AI assistants with instant access to TypeScript type definitions from your project dependencies. Enables generation of complete, type-safe mocks and test data by automatically discovering and exposing interface structures from node_modules.81MIT
