Public metadata, docs and connection examples for the LensUp remote MCP server — discover free browser-local document scanning tools (photo → PDF)
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
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.
- Machine-readable site summary for agents:
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.

Questions
What is the lensup-mcp MCP server?
Public metadata, docs and connection examples for the LensUp remote MCP server — discover free browser-local document scanning tools (photo → PDF)
Is lensup-mcp safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does lensup-mcp need?
No credential environment variables were found in its source, so it appears to need none.
How does lensup-mcp run?
It speaks streamable-http, so it runs as a service you connect to over the network.
How current is this page?
The grade is for one exact copy of the source (dd1c32f196dc), read on 2026-10-12. The repository is watched and re-audited when it changes.
