## ✅ What Was Accomplished


### 4.1 Official Worker Transport ✅

**Created**: `src/server/cloudflare-transport.ts`

**Components**:

- **CloudflareSseTransport**: Implements the official SDK `Transport` interface.
- **SSE Stream Management**: Handles connection setup, keepalives, and event dispatching.
- **Session Management**: Tracks active sessions using a global map.
- **Message Handling**: Routes POST messages to the correct session.

### 4.2 Unified Auth Middleware ✅

**Created**: `src/middleware/unified-auth.ts`

**Components**:

- **UnifiedAuthMiddleware**: Centralizes authentication logic for both OIDC and Static Tokens.
- **Transport Agnostic**: Works across HTTP and SSE transports.
- **Worker Integration**: Simplified `src/worker.ts` by removing inline auth checks.

### 4.3 Manifest Generation ✅

**Created**: `scripts/generate-manifest.ts`

**Components**:

- **Manifest Script**: Statically generates `manifest.json` from server capabilities.
- **Server Updates**: Added `listPrompts()` and updated `listResources()` in `BestPracticeLegalMCPServer`.
- **Worker Endpoint**: Added `GET /manifest.json` to serve the manifest dynamically.

### 4.4 Config Harmonization ✅

**Updated**: `mcp-config.json`, `claude_desktop_config.json`

**Components**:

- **Bridge Script**: `scripts/dev/mcp-remote.js` now handles the remote URL default.
- **Config Cleanup**: Removed hardcoded URLs from configuration files.
- **Consistency**: Aligned local and remote server definitions.

### 4.5 Build & CI Updates ✅

**Updated**: `package.json`, `wrangler.jsonc`, `Dockerfile`

**Components**:

- **Build Process**: `npm run build` now includes manifest generation.
- **Wrangler**: Updated entry point to `src/worker.ts` for proper bundling.
- **Docker**: Added `CMD` instruction to ensure container startup.
- **CI**: Verified build and protocol tests.
