How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
find_similar_papers ~205
Given ONE paper you already have (from a prior search result), return the most similar papers from the same corpus — semantic nearest neighbours, each with the full summary and code link. Use for 'more like this', 'related work', 'what else is in this line of work', or to expand a literature review. You can chain it: search -> pick a seed -> find_similar_papers -> repeat on a strong neighbour.
| Name | Type | Req | Description |
|---|---|---|---|
| item_id | string | yes | The seed paper's arXivSub id (uuid) from a prior search result. Never invent one. |
| item_type | string | yes | The seed paper's type, from its search 'source': 'arxiv' -> 'paper', 'conferences' -> 'ciiina'. |
| language | string | – | Summary language, 'en' or 'zh'. Default 'en'. |
| limit | integer | – | How many neighbours to return (server caps at 20). Default 8. |
No output schema declared.
No examples provided.
library_list ~120
List the user's personal arXivSub library — collections and saved items, optionally filtered. Use for 'what have I saved', 'show my library', 'which papers are in my <name> collection', 'what am I reading'.
| Name | Type | Req | Description |
|---|---|---|---|
| collection_name | string | – | Only items in this collection. |
| item_type | string | – | Only papers ('paper') or conference items ('ciiina'). |
| limit | integer | – | Max items (server caps at 200). Default 100. |
| status | string | – | Only items with this reading status. |
No output schema declared.
No examples provided.
library_save ~184
Save (or update) a paper in the user's personal arXivSub library. Use for 'save this', 'bookmark that paper', 'add it to my <X> collection', 'note that ...', 'mark as read'. Idempotent: saving the same paper again updates only the fields you pass and never duplicates. Cannot delete — removals are done on the website.
| Name | Type | Req | Description |
|---|---|---|---|
| collection_name | string | – | Optional collection/folder name; created automatically if it doesn't exist. |
| item_id | string | yes | The item's arXivSub id (uuid) from a prior search result. |
| item_type | string | yes | From the search 'source': 'arxiv' -> 'paper', 'conferences' -> 'ciiina'. |
| note | string | – | Optional note (<=2000 chars). |
| reading_status | string | – | Optional reading status. |
No output schema declared.
No examples provided.
research_insight ~326
Build aggregate pivot statistics over the arXivSub corpora — the same engine as the website's Custom Chart. Use for trends, rankings, breakdowns and comparisons: 'how has interest in diffusion models trended', 'top institutions in RL', 'papers per month by keyword', 'avg citations by affiliation'. Returns rows of {dim, breakdown, value} for you to interpret and visualize. Requires Pro or active trial days.
| Name | Type | Req | Description |
|---|---|---|---|
| breakdown | string|null | – | Optional second split, same value set as dim. e.g. dim=time:month, breakdown=keyword. |
| corpus | string | – | 'arxiv' (recent arXiv) or 'ciiina' (conferences; 'conference' is an alias). Default 'arxiv'. |
| dim | string | yes | REQUIRED axis. arxiv: time:day|week|month|year, keyword, category, affiliation, author, citation_bin. ciiina: time:year, keyword, conference, award, affiliation, author, citation_bin. |
| filters | object | – | Optional object: search, start_date, end_date, keywords[], categories[] (arxiv), conferences[]/publish_years[]/awards[] (ciiina), affiliations[]. |
| measure | string | – | count_papers (default) | count_authors | count_affiliations | count_keywords | avg_citation | median_citation | award_rate (ciiina only). |
| options | object | – | Optional object: top_n_dim, top_n_breakdown, min_count, show_others, sort. |
No output schema declared.
No examples provided.
search_papers ~345
Search academic papers from arXiv and major AI/CV/ML/robotics/NLP conferences via arXivSub (semantic + keyword search over a structured, summarized corpus). Use for 'find papers on X', 'latest research about Y', 'recent conference work on Z', or to start a literature review. Returns each paper with a 6-part summary (what it's about, innovations, techniques, datasets, results, limitations), authors + affiliations, pdf_url, and github_url when code is available.
| Name | Type | Req | Description |
|---|---|---|---|
| arxiv_days | integer | – | Only arXiv papers from the last N days. Default 30. |
| conference_years | array | – | Conference publication years to include, e.g. [2024, 2025]. Default: last two years. |
| has_code | boolean | – | If true, only return papers that ship a public code repository (a reproducibility signal). |
| language | string | – | Summary language, 'en' or 'zh'. Default 'en'. |
| limit | integer | – | Max papers per source (server caps at 100). Default 10. |
| locations | array | – | Venues to search (CASE-SENSITIVE): arxiv, CVPR, ICCV, ECCV, ICLR, ICML, NeurIPS, AAAI, MICCAI, CoRL, RSS, ACL, EMNLP, ICRA, IROS, IJCAI, SIGGRAPH, 'SIGGRAPH Asia'. Include 'arxiv' for arXiv preprints… |
| query | string | yes | Natural-language search query, e.g. 'LLM safety alignment'. |

io.github.arxivsub/arxivsub-mcp scores 77 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the io.github.arxivsub/arxivsub-mcp server expose?
io.github.arxivsub/arxivsub-mcp exposes 5 tools: search_papers, find_similar_papers, research_insight, library_save, library_list. Their descriptions and schemas cost roughly 1,180 tokens of context every time the server is loaded.
Is the io.github.arxivsub/arxivsub-mcp server still maintained?
io.github.arxivsub/arxivsub-mcp is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the io.github.arxivsub/arxivsub-mcp server under?
io.github.arxivsub/arxivsub-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
