Best Jest MCP Servers
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.8151,43417MITWhy 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.219144MITWhy this server?
Integrated for testing capabilities, supporting various test suites including integration tests, Exa Research API tests, and server tool registration tests
AlicenseAqualityAmaintenanceProvides advanced analytical, research, and natural language processing capabilities through a Model Context Protocol server, enabling dataset analysis, decision analysis, and enhanced NLP features like entity recognition and fact extraction.2124MITWhy this server?
Allows running Jest test suites on BrowserStack's cloud infrastructure for cross-browser and cross-device testing
AlicenseBqualityBmaintenanceBrowserStack MCP server513,048149AGPL 3.0Why this server?
Detects Jest testing framework for JavaScript projects in configuration analysis
AlicenseBqualityFmaintenanceA self-learning AI standards system that automatically detects patterns from user corrections and updates AI configuration files. Learns from repeated corrections (like 'use uv not pip') and automatically generates CLAUDE.md and other AI assistant configuration files.93MITWhy this server?
Generates Jest test code from Zebrunner test cases with intelligent framework detection and coverage analysis
AlicenseBqualityAmaintenanceIntegrates with Zebrunner Test Case Management to help QA teams manage test cases, test suites, and test execution data through AI assistants. Features intelligent validation, automated test code generation, and comprehensive reporting capabilities.49905AGPL 3.0Why this server?
Allows running Jest test suites and parsing results to provide pass/fail verdicts and failure details.
AlicenseAqualityCmaintenanceProvides an isolated workspace for testing candidate code, runs tests, and returns deterministic pass/fail verdicts. Enables automated grading of software engineering solutions by ensuring reproducible test runs.5MITWhy 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.1034MITWhy this server?
Enables unit testing capabilities for verifying functionality and ensuring code quality
AlicenseBqualityDmaintenanceA Node.js and TypeScript server project that provides a simple starter example with Express.js web server, supporting hot-reload, testing, and modular structure.2132ISC
