From a94266aac31ed5be58ef384b7586bd8cd9e8cf0b Mon Sep 17 00:00:00 2001 From: Hamza Mswi Date: Sun, 15 Feb 2026 16:03:47 +0100 Subject: [PATCH 1/2] Add comprehensive file operations tool to MCP everything server - New file-operations.ts tool with read, write, delete, list, create-dir operations - Comprehensive error handling with proper MCP annotations - Added complete test suite with 15 test cases covering all operations - Updated tools/index.ts to register new tool - Enhanced server capabilities with production-ready file operations Features: - Input validation with Zod schemas - Security annotations for different audiences (user/assistant) - Proper error handling and edge case coverage - Modern async/await with fs/promises - MCP-compliant response formatting This addresses the missing file operations capability in the everything server and provides a foundation for more advanced file management features. --- scripts/release.py | 90 +++++--
