List all scanners reachable from this machine.

Discovers network scanners over mDNS (eSCL/AirScan) and local USB scanners via the platform driver stack (WIA on Windows, SANE on Linux/macOS). Returns a JSON array of scanners with their id (pass this to scan_document), name, backend, connection type and supported sources.

Scan a document and return it so Claude can read it.

Args: scanner_id: Which scanner to use (from list_scanners). If omitted and exactly one scanner is found, that one is used; if several are found, an error lists them. source: auto | platen (flatbed glass) | adf (document feeder) | adf-duplex (feeder, both sides). resolution: DPI (150 fast, 300 documents, 600 fine). Default 300. color_mode: color | gray | lineart (1-bit black & white). output_format: png | jpeg | pdf. PDF is best for multi-page archives; images let Claude view the page inline. save_dir: Folder to save the scan in. Defaults to ~/Scans (or $SCANNER_MCP_SAVE_DIR). return_image: If true and the output is an image, the page images are returned inline so Claude can read the document directly. Ignored for PDF. ocr: If true, also OCR each page to text (requires Tesseract + pytesseract).

Returns a summary plus, when applicable, inline page images and/or OCR text.
