How to: Cursor Health & medicines rxnorm__approximate

client:Cursor transport:streamable-http tool:rxnorm__approximate

Add Health & medicines to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "health": {
      "url": "https://fourzerotwo.si/mcp/v/health"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something rxnorm__approximate does. Cursor lists the server's tools on connect and calls rxnorm__approximate itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Health & medicines's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
