What your AI can do with Paper Finder
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_papers”: Use this when the user wants papers on a topic, such as "find recent open-access papers on retrieval-augmented generation evaluation" or "sy.”
“Use “search_arxiv”: Use this when the user wants preprints from arXiv, such as "search arXiv for speculative decoding" or "newest cs.CL papers on tokenization".”
“Use “get_paper”: Use this when the user gives a DOI, PubMed id or arXiv id and wants the paper's abstract or a free full-text link, such as "get the abstract.”
“Use “submit_feedback”: Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feat.”
How secure is the Paper Finder MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Paper Finder holds up.
Official endpoint
Operated by Paper Finder (openkrill.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Paper Finder adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The Paper Finder MCP server at a glance
https://papers.openkrill.app/mcpQuestions, answered
Is there an official Paper Finder MCP server?
Yes — Paper Finder operates its own remote MCP server at papers.openkrill.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Paper Finder to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Paper Finder in the directory. No account or sign-in is needed. From then on, Paper Finder's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Paper Finder runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Paper Finder MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Paper Finder in minutes. No credit card required.
