RWE Life Sciences MCP Server

A local Model Context Protocol (MCP) server that exposes a single Real-World Evidence (RWE) tool to Claude. The tool returns aggregated, de-identified patient cohort statistics across four dimensions:

Dimension	Values
Age group	0-17, 18-34, 35-49, 50-64, 65-74, 75+
Gender	Male, Female, Unknown/Other
US Geography	4 Census regions + all 50 states + DC
Longitudinal	2018 – 2024 (year-over-year trend)

Disclaimer – All data is synthetically generated for demonstration purposes only. Do not use for clinical or regulatory decisions.

Connect to Claude Desktop

Open (or create) claude_desktop_config.json:

OS	Path
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Windows	`%APPDATA%\Claude\claude_desktop_config.json`

Add the server entry below (replace /absolute/path/to/ with your actual path):

{
  "mcpServers": {
    "rwe-life-sciences": {
      "command": "python",
      "args": ["/absolute/path/to/rwe_mcp_server/server.py"],
      "env": {
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

If you use a virtual-environment interpreter:

{
  "mcpServers": {
    "rwe-life-sciences": {
      "command": "/absolute/path/to/.venv/bin/python",
      "args": ["/absolute/path/to/rwe_mcp_server/server.py"],
      "env": {
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

Restart Claude Desktop. The 🔧 tool icon should show rwe-life-sciences connected.

Quick start

1. Install dependencies

cd rwe_mcp_server
pip install -r requirements.txt

2. Run the server

python server.py

The server starts on Streamable HTTP at:

MCP endpoint: http://127.0.0.1:9090/mcp
Health endpoint: http://127.0.0.1:9090/health

You can override the bind address, port, or transport:

MCP_HOST=0.0.0.0 MCP_PORT=9090 python server.py
MCP_TRANSPORT=stdio python server.py
