alphaXiv
Keyword and embedding search across the arXiv preprint corpus
Overview
What alphaXiv does
alphaXiv publishes a retrieval layer over arXiv. The connector, at partner tier, describes both keyword and embedding search across the corpus, plus full-text access to the papers themselves, so a conversation can be grounded in specific preprints rather than in recollection of them. Six tools are claimed. The listing copy is brief and does not name the individual tools or say whether full text comes back whole or in passages. Documentation and an endpoint URL are on file, and the record is filed under Data & Analytics.
Tool surface
Six tools are claimed and the endpoint answers 401 instead of naming them, so whether keyword search, embedding search, and full-text retrieval are separate calls stays unresolved.
Availability
Where alphaXiv is listed
alphaXiv is listed in the Claude connectors directory only. alphaXiv has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.
Claude listing
In the Claude connectors directory
alphaXiv publishes 6 tools to Claude. That is a mid-sized surface: 28.1% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Data & Analytics publishes 12, so this one sits 6 tools below its bucket's median, 142nd of 198.
It falls in the 4-6 tools band, which holds 16.2% of the Claude directory.
alphaXiv publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

alphaXiv carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.

This is an independent catalogue entry compiled by Node8 from alphaXiv's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with alphaXiv, and inclusion here is not an endorsement.
