Pull Request Overview
This PR refactors the MCP (Model Context Protocol) implementation to unify header management patterns and improve type safety. The changes focus on standardizing how MCP servers initialize and manage API headers while adding safety features for destructive operations.
- Unified header management with consistent
initializeMCPHeaders()pattern across CLI and Worker implementations - Enhanced type safety by removing unnecessary type casting and improving interface definitions with proper TypeScript types
- Added destructive hints to self-targeting override tools to warn users about potentially dangerous operations

Adding noEmit: true to a TypeScript configuration that has an outDir specified is contradictory. The noEmit flag prevents TypeScript from generating output files, making the outDir setting meaningless. Consider removing either noEmit: true or the outDir setting based on whether you want TypeScript to emit files or just perform type checking.
