Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {

Run this in your terminal

claude mcp add arxivsub --env ARXIVSUB_SKILL_KEY=your-value -- npx -y arxivsub-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "servers": {
    "arxivsub": {

      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Arxivsub MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ARXIVSUB_SKILL_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

arxivsub-mcp

An MCP server for [arXivSub](https://arxivsub.comfyai.app) — search arXiv and the top AI / CV / ML / robotics / NLP conferences, follow any paper to its related work, build research analytics, and manage a personal library, straight from your AI agent (Claude Desktop, Cursor, Cline, Claude Code, Windsurf, …).

arXivSub summarizes every paper into a structured 6-part breakdown (what it's about, innovations, techniques, datasets, results, limitations) and indexes it for semantic search across arXiv + CVPR, ICCV, ECCV, ICLR, ICML, NeurIPS, AAAI, MICCAI, CoRL, RSS, ACL, EMNLP, ICRA, IROS, IJCAI, SIGGRAPH, SIGGRAPH Asia. This server puts that engine directly in your agent's hands.

Get a free key (7-day trial, no credit card)

Sign in at https://arxivsub.comfyai.app/skills with email or Google.
Copy your API key from the Skills page.
Put it in the server config below as ARXIVSUB_SKILL_KEY.

New accounts get a 7-day free trial of the full skill. After that it's part of arXivSub Pro.

Install

The server runs via npx — no manual install needed. Add it to your MCP client's config.

Claude Desktop (claude_desktop_config.json), Cursor (~/.cursor/mcp.json), Windsurf, Cline, etc.:

"mcpServers": { "arxivsub": { "command": "npx", "args": ["-y", "arxivsub-mcp"], "env": { "ARXIVSUB_SKILL_KEY": "your_key_here" } } } }

Claude Code:

claude mcp add arxivsub --env ARXIVSUB_SKILL_KEY=your_key_here -- npx -y arxivsub-mcp

Codex CLI:

codex mcp add arxivsub --env ARXIVSUB_SKILL_KEY=your_key_here -- npx -y arxivsub-mcp

Or add it to ~/.codex/config.toml directly:

[mcp_servers.arxivsub]

command = "npx" args = ["-y", "arxivsub-mcp"] env = { ARXIVSUB_SKILL_KEY = "your_key_here" }

Restart your client and the tools below become available.

claude.ai (remote connector)

On claude.ai there's nothing to install, add a hosted connector:

Settings → Connectors → Add custom connector
Name: arxivsub
Remote MCP server URL (replace YOUR_KEY with your key from https://arxivsub.comfyai.app/skills):

   https://qtevnmgyobilaanrzidq.supabase.co/functions/v1/mcp?key=YOUR_KEY

Leave the OAuth fields empty and click Add.

This is a hosted Streamable HTTP MCP endpoint, a thin adapter over the arXivSub gateway exposing the same tools. Source: supabase/functions/mcp/index.ts.

Tools

Tool	What it does
`search_papers`	Semantic + keyword search over arXiv and conferences. Filters: venues, recency, year, `has_code`. Returns each paper's 6-part summary, authors, PDF, and code link.
`find_similar_papers`	Nearest-neighbour "related work" for a paper you already found. Chainable for a mini literature review.
`research_insight`	Pivot analytics (the website's Custom Chart engine): trends, rankings, breakdowns. Pro / trial.
`library_save`	Save/update a paper in your personal library — notes, reading status, collections.
`library_list`	List your saved papers and collections.

Just ask your agent naturally — *"find recent papers on LLM safety with code"*, *"more work like this one"*, *"how has interest in diffusion models trended by month"*, *"save this to my "to read" collection"* — and it will pick the right tool.

Notes

Case-sensitive venues: arxiv, CVPR, ICCV, ECCV, ICLR, ICML, NeurIPS, AAAI, MICCAI, CoRL, RSS, ACL, EMNLP, ICRA, IROS, IJCAI, SIGGRAPH, SIGGRAPH Asia.
Quota: each search / similar / insight call uses one daily quota unit; library calls are free. The remaining quota is returned with every result.
Privacy / security: the server only holds your skill key and talks to the arXivSub gateway over HTTPS. It has no direct database access and no service credentials.
