Code Reasoning MCP Server

# Changelog ## Unreleased ## 0.8.0 (2025-09-23) ### Major Changes - Migrated from class-based `SequentialThinkingServer` to functional `McpServer`. - Simplified config: replaced `config-manager` with lightweight `buildConfig`. - Introduced MCP regression framework (147 tests) with improved docs. - Consolidated prompt handling into `PromptManager` with filtering and validation. - Upgraded to MCP SDK `v1.18.1`. - Removed custom prompt loading for security and consistency. ### Features - Structured logging with tool metadata and error handling. - Prompt argument filtering for global values. - Added tests for literal braces in templates. ### Improvements - Updated npm dependencies. - Debug logs now go to `stderr`. - Simplified entry point (removed `parseArgs` and CLI options). - Updated schema handling with `ThoughtDataInputShape`. - Docs aligned with new architecture. - Reduced bundle size (removed `chalk`). - Refined validation with dual-schema/Zod-inferred types. - Better shutdown handling with proper exit codes. ### Breaking Changes - Removed end-to-end test runner, prompt evaluation, and related infra (\~2,200 LOC). - Dropped `valueManager` (merged into `PromptManager`). - Removed custom transport handling. - Replaced `zodToJsonSchema` with direct schemas. - Eliminated CLI options and debug flag handling. - Replaced manual `ThoughtData` interface with Zod-inferred types and strict/loose schemas. ### Bug Fixes - Fixed debug logging stream (no MCP interference). - Improved prompt filtering to respect declared args. - Strengthened error handling and type safety (`CallToolResult` replaces `ServerResult`). - Removed overzealous template injection neutralization. ## 0.7.0 (2025-05-10) ### Features - Added comprehensive MCP prompts system with predefined templates - Includes architecture-decision, bug-analysis, code-review, feature-planning, and refactoring-plan prompts - The last prompt value is saved so that it can be used again but it will not show until Claude Desktop and Claude Code implement MCP CompleteRequestSchema. See https://github.com/anthropics/claude-code/issues/986 - Added support for custom prompt templates via JSON files - Added Zod-based input sanitization to template processing ## 0.6.2 (2025-05-04) ### Features - Added tool annotations support to better inform clients about the tool's behavior - Updated MCP SDK version reference to 1.11.0 ### Improvements - Updated ESLint ecosystem to major new versions - ESLint: 8.57.1 → 9.26.0 - @typescript-eslint/parser: 7.18.0 → 8.31.1 - @typescript-eslint/eslint-plugin: 7.18.0 → 8.31.1 - Added ESLint v9 flat config support via eslint.config.js - Removed obsolete .eslintrc.json configuration - Added GitHub Actions CI/CD workflows and contribution templates - Added CI badge and Contributing section to README ## 0.6.1 (2025-05-02) ### Bug Fixes - Fixed "Maximum call stack size exceeded" error in FilteredStdioServerTransport by preventing recursive stdout.write calls - Improved stdout filtering mechanism to avoid circular references when filtering non-JSON output ### Improvements - Doubled default operation timeout from 30s to 60s for better handling of complex reasoning tasks ## 0.6.0 (2025-04-30) ### Features - Upgraded MCP SDK from 0.5.0 to 1.10.2 for enhanced protocol compatibility - Added support for additional protocol capabilities (resources, prompts) - Implemented custom FilteredStdioServerTransport for improved stability - Added handlers for ListResourcesRequestSchema and ListPromptsRequestSchema ### Technical Improvements - Leveraged zodToJsonSchema utility for schema generation rather than manual creation - Documented intent of empty resource and prompt handlers to prevent Claude Desktop errors - Refined JSON detection logic in FilteredStdioServerTransport to handle array literals - Simplified type aliases by using direct SDK types for better maintainability - Improved file header documentation with MCP SDK version information and clearer feature descriptions - Updated type definitions for newer SDK compatibility - Added zod-to-json-schema dependency - Reorganized server.ts with clear section headers for better code organization - Enhanced code performance with cached JSON schema and optimized validation - Improved type safety with readonly properties and Map instead of object literals ## 0.5.0 (2025-04-30) ### Features - Updated core prompt to use HYBRID_DESIGN for better reasoning performance - Added prompt evaluation system with documentation and examples - Enhanced end-to-end test framework - Increased maxThoughtLength for more complex reasoning tasks ## 0.4.0 (earlier release) Initial documented version.
