Overview

What PDF Viewer does

A demonstration connector from the Model Context Protocol community rather than a product. It renders PDFs from a restricted set of allowed sources, arxiv.org among them, with the restriction described as a security measure. The listing records one tool while the endpoint returns four, and two of those, byte-range reading and saving, carry descriptions instructing the model not to call them directly, which indicates they exist to back the viewer component rather than to be invoked as tools. The presence of a save path means this is not purely a reader. The tier is partner despite the demonstration framing.

Who it is for

Developers evaluating MCP app rendering rather than teams with a document workflow.

Tool surface

Four tools came back against the one claimed: list_pdfs and display_pdf for the viewer, plus read_pdf_bytes and save_pdf, whose own descriptions tell the model not to call them. The save path means the surface is not read-only.

Availability

Where PDF Viewer is listed

PDF Viewer is listed in the Claude connectors directory only. Model Context Protocol Community has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.

Claude listing

In the Claude connectors directory

PDF Viewer publishes 1 tool to Claude, a deliberately narrow surface; only 0.7% of the 1,253 Claude-listed connectors expose fewer.

The median Claude-listed connector filed under Productivity publishes 12, so this one sits 11 tools below its bucket's median, 439th of 462.

It falls in the 1-3 tools band, which holds 16.4% of the Claude directory.

Measured against the live endpoint

A direct call to the endpoint returned 4 tools, 3 more than the 1 the listing publishes. Probed 2026-08-07.

Tools the server actually returns

  • list_pdfs
  • read_pdf_bytes
  • display_pdf
  • save_pdf

PDF Viewer publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.

Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Snapshot
August 2026

PDF Viewer carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.

In the publisher's words

How Model Context Protocol Community describes it

Demo interactive PDF viewer that renders PDFs from a limited set of allowed URLs (e.g., arxiv.org) for security reasons.
