DocNexus MCP Server

Search US healthcare providers, key opinion leaders (KOLs), executives and organizations from any AI assistant, backed by DocNexus's de-identified claims data.

This is a hosted, remote MCP server. There is nothing to install or run. This repository holds documentation only; the server source is not public.

  • Registry name: ai.docnexus.mcp/docnexus

Configure

You need a DocNexus account. Sign-in uses OAuth 2.0 with PKCE; your client opens a browser window the first time you connect.

GitHub Copilot (VS Code)

Add to .vscode/mcp.json:

{
  "servers": {
    "docnexus": {
      "type": "http",
      "url": "https://mcp.docnexus.ai/mcp"
    }
  }
}

Start the server from the MCP view and sign in when prompted.

  • "Which organizations have the highest patient volume for knee replacement in Ohio?"
  • "Show the patient volume trend for GLP-1 prescriptions over the last 3 years."
  • "Look up NPI 1234567890 and list their affiliations."
