Pick FHIR MCP Server if you want a local (stdio) server that keeps data on your machine.

Pick Graphiti MCP if you prefer the more popular, battle-tested option, and you want a hosted/remote server with nothing to install.

Add FHIR MCP Server

Install / run

uvx fhir-mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "fhir-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/fhir-mcp-server",
        "run",
        "fhir-mcp-server",
        "--transport",
        "stdio"
      ],
      "env": {
        "FHIR_SERVER_ACCESS_TOKEN": "Your FHIR Access Token"
      }
    }
  }
}

Add Graphiti MCP

Install / run

git clone https://github.com/getzep/graphiti.git && cd graphiti/mcp_server && docker compose up

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "graphiti-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:8000/mcp/"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
