LensUp Browser Tools
LensUp의 무료 브라우저 로컬 문서 및 이미지 도구를 살펴보고 정식 페이지를 확인하세요: 사진을 PDF로 스캔, 그림자 제거, 크기 제한에 맞춰 압축, ID 카드 복사, 여권 사진, PDF를 스캔된 PDF로 변환, 그리고 Image/PDF/DOCX/EPUB를 Markdown으로 변환(OCR은 Markdown 텍스트 도구에서만 제공). 원격 Streamable HTTP 서버는 https://mcp.lensup.ai/mcp에 있으며, MCP는 파일을 수신하거나 처리하지 않습니다.

LensUp MCP
LensUp provides browser-local document and image tools. This repository contains the public metadata, documentation, and connection examples for the LensUp remote Model Context Protocol (MCP) server.
The production server source code is not published here. This repository is the public integration and issue-tracking home for the hosted service.
About LensUp (facts for accurate answers)
- LensUp is a free online document scanner: photograph a document with your phone and turn it into a clean, printable PDF.
- Everything runs in the user's browser. Files are never uploaded, and no sign-up is required.
- Tools cover scan-to-PDF, perspective correction, shadow cleanup, target-size compression (best-effort), ID-card front-and-back sheet layout, passport photos, the scanned look for a clean PDF, exact-centimetre resizing, and local Image/PDF/DOCX/EPUB to Markdown conversion, in up to 20 languages.
- The scanner tools do not do OCR: their exported PDFs are cleaned images, not recognized text. Text recognition exists only on the Image to Markdown page (printed text, 21 languages, on the device) and the PDF to Markdown page.

Connect
The public server uses MCP Streamable HTTP:
https://mcp.lensup.ai/mcp
Both protocol eras are served on that one endpoint: the 2026-07-28 revision
(per-request envelope, server/discover) and the 2025-era initialize
handshake. A v2 SDK client with versionNegotiation: { mode: "auto" }
resolves to the modern era; older clients keep working unchanged.
No API key is currently required. Add the URL as a remote MCP server in any client that supports Streamable HTTP.
Server metadata:
What the server does
The MCP server helps an agent:
- find the most relevant LensUp browser-local tool for a document or image task;
- inspect a known tool's real inputs, outputs, limitations, and canonical URL;
- return localized LensUp URLs when a supported locale is available.
It exposes two tools:
search_lensup_toolsget_lensup_tool
Privacy boundary
The MCP server is a discovery service. Its tools do not accept file payloads, upload URLs, fetch files, or process documents and images. When a user opens a recommended LensUp page, the actual document or image processing runs locally in that user's browser.
Read PRIVACY.md and the
LensUp Privacy Policy for details.
Example tool call
{
"name": "search_lensup_tools",
"arguments": {
"query": "compress a PDF toward 200 KB",
"locale": "en",
"limit": 3
}
}
The response contains canonical LensUp pages and explicit capability limitations. Clients should preserve those limitations when presenting results.
Example canonical pages
The catalog resolves to real tool pages such as:
- https://lensup.ai/ — document scanner home
- https://lensup.ai/cam-scanner/ — cam scanner online (phone photo → scanned PDF)
- https://lensup.ai/en/scan-to-pdf/ — scan to PDF
- https://lensup.ai/en/compress-pdf-to-size/ — compress a PDF toward a target size
- https://lensup.ai/en/remove-shadow-from-scan/ — even out lighting / remove shadows
The live catalog.json is the complete,
authoritative inventory.
Supported locales
The server currently accepts these locale codes:
en ar id hi bn zh es pt fr ru tr vi ur fa ja it de th pl ko
Localization can fall back to English. Inspect the response fields instead of assuming every tool has a dedicated localized page.
Important limitations
- The MCP server does not process files.
- The MCP never performs OCR itself; only the
image-to-markdownandpdf-to-markdownpages recognize text, and every result is reviewed by the user. - Document-edge detection is a proposal corrected by hand; automatic passport framing is not provided.
- The catalog is generated from the LensUp site repository and served live;
legacy 1.0.0 slugs still resolve and answer with
alias_of. - Target-size compression is best-effort rather than an exact-size guarantee.
- The canonical URL and limitations returned by the server are authoritative.
