-## 🔥 Latest Features: Storage Upload (v1.3.3)
-
-Firebase MCP now offers powerful file upload capabilities with two specialized tools:
-
-- **`storage_upload`**: Upload files from text, base64 content, or local file paths
-- **`storage_upload_from_url`**: Import files directly from external URLs
-
-### Key Benefits
-
-- **Permanent Public URLs**: All uploads generate non-expiring public URLs
-- **Content Type Detection**: Automatic detection from file extensions and data
-- **Multiple Upload Methods**: Flexible options for different use cases
-- **Rich Response Formatting**: Clear, well-structured upload confirmations
-
-### Upload Methods
-
-1. **Local File Path** (Recommended for all file types)
-   ```ts
-   {
-     filePath: "my-report.pdf",
-     content: "/path/to/local/file.pdf"
-   }
-   ```
-
-2. **Base64 Data URL** (For smaller files)
-   ```ts
-   {
-     filePath: "my-image.png",
-     content: "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..."
-   }
-   ```
-
-3. **Plain Text** (For text files)
-   ```ts
-   {
-     filePath: "readme.md",
-     content: "# My README\n\nThis is a markdown file."
-   }
-   ```
-
-4. **External URL** (Using storage_upload_from_url)
-   ```ts
-   {
-     filePath: "document.pdf",
-     url: "https://example.com/document.pdf"
-   }
-   ```
-
-> ⚠️ **Important:** For binary files like images and PDFs, always use the direct file path method for best reliability.
