Security Report

5.2

Moderate5.2Moderate Risk

This is a well-structured MCP server with proper authentication, secure API key handling, and appropriate input validation. The code follows security best practices by using environment variables and context variables for credential management, validating user input on sensitive operations, and cleanly separating concerns. Minor code quality observations do not materially affect security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

MedData MCP Server

mcp-name: io.github.anthesiallc/meddata

A Model Context Protocol server that exposes the MedData API as tools, so any MCP client (Claude Desktop, Cursor, ChatGPT connectors, or an agent framework) can look up drug and supplement data and check interactions conversationally.

It's a thin wrapper: each tool maps to one MedData REST endpoint. All the data work happens in the API.

Tools

Tool	What it does
`search_drugs`	Search drugs by brand or generic name; returns RxCUI + details
`get_drug`	Full drug profile by RxCUI
`get_drug_by_ndc`	Drug profile by NDC package code
`search_supplements`	Search supplements by name; returns supplement IDs
`get_supplement`	Full supplement fact sheet by ID
`check_interactions`	Interactions across a mixed list of 2-10 drugs/supplements
`get_usage`	Current billing period usage and plan limit

Get an API key

Free tier is 250 calls/month, no credit card:

curl -X POST https://meddata.anthesia.io/api/v1/signup \
  -H 'Content-Type: application/json' \
  -d '{"email":"you@example.com"}'

The key comes back in the api_key field of the response.

Install and run

The easiest way is with uv (no manual venv needed):

# stdio transport (default — for Claude Desktop, Cursor, most local clients)
MEDDATA_API_KEY=md_your_key uvx meddata-mcp

# streamable-HTTP transport (for remote / web clients)
MEDDATA_API_KEY=md_your_key uvx meddata-mcp --http

Or install with pip into its own environment:

pip install meddata-mcp
MEDDATA_API_KEY=md_your_key meddata-mcp

Note: install into a dedicated environment. The mcp SDK requires a newer starlette than the MedData API app pins, so the two will conflict if installed together.

Environment variables:

MEDDATA_API_KEY (required) — your MedData API key.
MEDDATA_BASE_URL (optional) — defaults to https://meddata.anthesia.io.
MEDDATA_TIMEOUT (optional) — request timeout in seconds, default 30.

Client configuration

Claude Desktop

Add to claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "meddata": {
      "command": "uvx",
      "args": ["meddata-mcp"],
      "env": { "MEDDATA_API_KEY": "md_your_key" }
    }
  }
}

Cursor

Add the same block to ~/.cursor/mcp.json (or the project .cursor/mcp.json).

Develop from source

cd mcp_server
python -m venv .venv
.venv/Scripts/python -m pip install -e .   # Windows
# .venv/bin/pip install -e .                # macOS/Linux
MEDDATA_API_KEY=md_your_key .venv/Scripts/python -m meddata_mcp.server

Notes

Data is for informational purposes only and is not medical advice.
Interaction data comes from established medical databases; an empty result means none were found in those sources, not that a combination is proven safe.
