Vitest MCP Server

# Changelog All notable changes to the Vitest MCP Server will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Changed - **BREAKING**: Removed MCP server's ability to set or override coverage thresholds - Coverage thresholds are now read exclusively from `vitest.config.ts` files - Removed all threshold-related CLI arguments (`--threshold`, `--coverage-threshold-*`) - Removed threshold-related environment variables (`VITEST_MCP_COVERAGE_THRESHOLD*`) - `analyze_coverage` tool responses only include threshold information when thresholds are configured in Vitest config - Projects without configured thresholds will not receive threshold-related fields in responses ### Added - New `vitest-config-reader` utility to extract thresholds from Vitest configuration files - Graceful error handling for future Vitest configuration schema changes - Comprehensive validation and type checking for threshold values ### Fixed - Threshold detection now uses parsed coverage percentages compared against configured thresholds - Proper handling of projects that don't specify coverage thresholds - Updated all documentation to reflect that thresholds should be configured in `vitest.config.ts` ## [0.4.1] - 2024-12-06 ### Fixed - Enhanced Claude Code hook to intercept npm/yarn/pnpm scripts that run vitest - Added support for script names with colons (test:unit) and dashes (test-coverage) - Hook now parses package.json to detect vitest-based scripts - Improved bypass flag (`--bypass-hook`) flexibility - works in multiple positions ## [0.4.0] - 2024-12-06 ### Added - Comprehensive test suite with unit and integration tests - Support for `vitest.mcp.config.ts` - MCP-specific configuration file that takes priority over regular vitest/vite configs - New `config-finder` utility to intelligently locate configuration files with proper priority order - Example configuration file (`vitest.mcp.config.example.ts`) demonstrating MCP-specific settings - Path security validation with traversal protection - Development mode support with VITEST_MCP_DEV_MODE environment variable ### Changed - Configuration file detection now follows priority order: vitest.mcp.config.ts > vitest.config.ts > vitest.config.js > vitest.config.mjs > vite.config.ts > vite.config.js > vite.config.mjs - Updated `run-tests` tool to use the prioritized configuration when setting up log capture - Updated `project-context` to use the new config finder for project validation - Enhanced coverage analysis with threshold validation and insights - Improved test runner with better output capture and formatting - Refactored MCP server initialization for better error handling ### Documentation - Added configuration priority documentation to README - Added example of MCP-specific configuration usage ## [0.3.0] - 2024-01-XX ### Added - Plugin architecture for extensible tool system - Coverage gap analysis with line-by-line insights - Console log capture for debugging test failures - Multi-repository support with context switching - Development mode with enhanced debugging ### Changed - Complete refactor to type-safe plugin architecture - Improved error handling with user-friendly hints - Enhanced structured JSON output for AI consumption ## [0.2.0] - Previous Release ### Added - Initial MCP server implementation - Basic test execution with JSON output - Coverage analysis tool - Test listing functionality
