# alphaXiv — AI Connector alphaXiv publishes 6 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/data-analytics/alphaxiv/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Data & Analytics](https://node8.ai/ai-connectors/data-analytics/) # alphaXiv Keyword and embedding search across the arXiv preprint corpus Listed in Claude · 6 published tools · Verified partner [Claude connector docs](https://www.alphaxiv.org/docs/mcp) [alphaxiv.org](https://www.alphaxiv.org/) 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. ### Who it is for Researchers and engineers who need current papers cited accurately in their work. ### 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. Publisher alphaXiv Verification Verified partner (37.8% of the Claude directory) Filed under Data & Analytics Endpoint `https://api.alphaxiv.org/mcp/v1` Documentation [Publisher setup docs](https://www.alphaxiv.org/docs/mcp) Published tools 6 · 4-6 tools band Depth rank in Data & Analytics 142 of 198 Snapshot August 2026 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.

Give your agent context on the latest research papers. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
