What it does

Document Viewer renders an interactive ALTO XML visualization overlay inside MCP Apps-compatible hosts. Load a document and browse it with an interactive overlay that highlights text lines. Select any line to translate it, or fetch the entire document text for batch translation — all driven by MCP tools exposed to the AI host.

Key features

ALTO XML overlay — renders structured document pages with an interactive text-line overlay for precise selection
Text-line selection and translation — click a line to translate it via the text-line-selected tool
Full document text extraction — fetch-all-document-text retrieves every line for batch processing or translation
Svelte 5 UI — modern reactive interface built with Svelte 5 and bundled as a single-file MCP app
Dual transport — supports both stdio and HTTP server modes for flexible deployment
