Overview

AI-generated overview

Lets an assistant look up clinical trials, drug names, FDA drug and device records, PubMed literature, and NHS organisations.

What you can do
This remote MCP server exposes health and medicines data sources to an assistant. It covers clinical trial records, RxNorm drug lookups, FDA drug and device data, PubMed literature, and NHS organisation information. The manifest does not list individual tool names, so the exact call set is not documented here.
When to use it
Useful when an assistant needs to answer questions about drugs, trials, regulatory records, medical literature, or UK health organisations without the user opening each source manually. Best suited to research or reference lookups rather than clinical decision-making.
Requirements
A remote streamable HTTP endpoint at the provider's site; nothing to install locally. No account is required, but an optional free API key can be sent in the X-API-Key header to raise the daily call allowance from 100 to 500. Network access to the provider is needed.
Before you install
The optional X-API-Key header carries a secret; treat it as a credential and do not share it. Queries are sent to a third-party service, so avoid submitting confidential or patient-identifying information. The manifest declares no authentication, so anyone reaching the endpoint can use the free allowance.

Installation

In SourceWeft

  1. Open Health & medicines in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/si.fourzerotwo%2Fhealth/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
