What you can do
Search arXiv and major conferences by semantic and keyword queries, with filters for venue, recency, year and code availability, returning structured six-part paper summaries, authors, PDF and code links. Find related work for a paper already found, chainable into a short literature review. Run research analytics such as trends, rankings and breakdowns. Save and update papers in a personal library with notes, reading status and collections, and list saved papers and collections.
When to use it
Useful when you want an assistant to do literature searches across arXiv and top AI, CV, ML, NLP and robotics venues, follow a paper to related work, or keep a reading library without leaving the chat client.
Requirements
Runs locally over stdio via npx, so Node.js is needed, or you can use the hosted remote connector on claude.ai. Requires an arXivSub account and API key supplied as the ARXIVSUB_SKILL_KEY environment variable. Network access to the arXivSub gateway.
Before you install
The server holds your arXivSub API key and sends queries to the arXivSub gateway over HTTPS. The key is tied to a paid service: a 7-day free trial, then part of arXivSub Pro. Search, similar-paper and insight calls consume a daily quota unit, while library calls are free. Library save and update tools write to your personal library. The remote connector puts the key in the URL.

Installation

In SourceWeft

  1. Open Arxivsub Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

arxivsub-mcp

An MCP server for arXivSub — 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)

  1. Sign in at https://arxivsub.comfyai.app/skills with email or Google.
  2. Copy your API key from the Skills page.
  3. 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.:

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

Claude Code:

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

Codex CLI:

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

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

toml
[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:

  1. Settings → Connectors → Add custom connector

  2. Name: arxivsub

  3. 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

  4. 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

ToolWhat it does
search_papersSemantic + 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_papersNearest-neighbour "related work" for a paper you already found. Chainable for a mini literature review.
research_insightPivot analytics (the website's Custom Chart engine): trends, rankings, breakdowns. Pro / trial.
library_saveSave/update a paper in your personal library — notes, reading status, collections.
library_listList 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.

Development

bash
npm installnpm run build           # tsc -> dist/ARXIVSUB_SKILL_KEY=... node dist/index.js   # run over stdio

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
