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.
ARXIVSUB_SKILL_KEY.New accounts get a 7-day free trial of the full skill. After that it's part of arXivSub Pro.
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.:
Claude Code:
Codex CLI:
Or add it to ~/.codex/config.toml directly:
Restart your client and the tools below become available.
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):
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.
| 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.
