# DocNexus Advanced Search MCP — AI Connector DocNexus Advanced Search MCP publishes 11 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/healthcare/docnexus-advanced-search-mcp/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Healthcare & Life Sciences](https://node8.ai/ai-connectors/healthcare/) # DocNexus Advanced Search MCP Search US providers and health systems by claims volume Listed in Claude · 11 published tools · Community-listed [Claude connector docs](https://mcp.docnexus.ai/) [docnexus.ai](https://docnexus.ai/) Overview ## What DocNexus Advanced Search MCP does DocNexus builds on de-identified US medical and pharmacy claims, and this connector exposes its Advanced Search product. Individual providers can be found by specialty, geography, affiliation and what they actually diagnose, treat or prescribe; executives and leadership can be located across health systems, hospitals and firms. Beyond lookup, the same data supports ranking providers or organisations by claim or patient volume for a defined clinical market, sizing that market in total claims or unique patients, charting patient volume over time, and listing a provider's organisational affiliations. Queries run under the caller's own DocNexus account and return only entitled data. Eleven tools are declared. ### Who it is for Commercial and medical affairs teams in pharma and medtech targeting providers. ### Tool surface Entitlements differ by DocNexus account, so a 401 in front of tools/list is consistent with that model, and the eleven tools go unenumerated here. Availability ## Where DocNexus Advanced Search MCP is listed DocNexus Advanced Search MCP is listed in the Claude connectors directory only. DocNexus AI 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 DocNexus Advanced Search MCP publishes 11 tools to Claude. That is a mid-sized surface: 48% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Healthcare & Life Sciences publishes 6, so this one runs 5 tools above its bucket's median and ranks 8th of 51 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. DocNexus Advanced Search MCP 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 DocNexus AI Verification Community-listed (61.5% of the Claude directory) Filed under Health & Life Sciences Endpoint `https://mcp.docnexus.ai/mcp` Documentation [Publisher setup docs](https://mcp.docnexus.ai/) Published tools 11 · 11-20 tools band Depth rank in Healthcare & Life Sciences 8 of 51 Snapshot August 2026 DocNexus Advanced Search MCP is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How DocNexus AI describes it > DocNexus turns real-world healthcare data into answers. This connector lets Claude search DocNexus Advanced Search — a database built on de-identified US medical and pharmacy claims — directly in your conversation. Ask in plain English and Claude will find and rank the right people and organizations, then explain what it found: • Find individual providers (HCPs) by specialty, geography, affiliation, and what they diagnose, treat, or prescribe. • Find healthcare executives and leadership at systems, hospitals, and firms. • Rank the top providers or organizations by claim or patient volume for any clinical market (a diagnosis, procedure, or drug). • Size a market — total claims or unique patients for a clinical definition. • Chart patient-volume trends over time. • See a provider's organizational affiliations. Every query runs as your own DocNexus account, returning only data you already have access to. Codes and names are resolved to canonical values automatically, and results include the underlying query for full transparency. This connector is a fast way to explore and qualify. Deeper workflows — referral-network mapping, opportunity maps, exports, and saved lists — live in the DocNexus platform, which the connector links you to when relevant. You need a DocNexus platform account to use it. 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.
