Overview

AI-generated overview

Searches the WHO ICTRP clinical trials portal across ClinicalTrials.gov and WHO primary registries, and returns full records for individual trials.

What it does
Provides two tools: ictrp_search, which finds trials by free-text query and by condition, intervention, sponsor or source registry, returning trial id, registry, recruitment status, registration date, results-posted flag and record URL; and ictrp_trial, which returns the full record for one trial by registry id, including titles, sponsor, status, design, phase, countries, conditions, interventions, outcomes, eligibility, sample size, dates, funding and ethics review status. Responses carry a data_as_of timestamp, and trial records include last_refreshed_on.
When to use it
Useful when you need to find clinical trials registered outside the United States, especially Chinese, Japanese, Indian or Iranian registries, or to pull the WHO Trial Registration Data Set for a specific trial. The README suggests pairing it with the clinicaltrials, isrctn and anzctr packs.
Requirements
A remote streamable HTTP endpoint at the provider's gateway; no account, API key or environment variable is declared for the pack endpoint. A local stdio option is also documented via npx, which needs Node.js. Network access to the gateway and the WHO portal is required.
Before you install
The endpoint also exposes shared gateway meta-tools such as ask_pipeworx, discover_tools, search_within, remember and recall, so the listed tool count is larger than the pack's own tools. The README states the integration is independent and unofficial, that the portal has no JSON API and is read through public result and record pages, and that the XML/CSV export is not used because its terms restrict commercial use. Records contain contact persons and ethics committee contacts, which the tool…

Installation

In SourceWeft

  1. Open Who Ictrp 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.

Other MCP clients

Add this to your client's mcpServers config.

README

@pipeworx/who-ictrp

WHO International Clinical Trials Registry Platform (trialsearch.who.int): one search across ClinicalTrials.gov and the WHO primary registries (ChiCTR, jRCT, CTRI, IRCT, DRKS, ANZCTR, ISRCTN, EU CTR/CTIS and more), plus the WHO Trial Registration Data Set for any one trial. It is the practical way to find Chinese, Japanese, Indian and Iranian trials next to the rest.

Part of Pipeworx — an MCP gateway connecting AI agents to 1764+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

  • ictrp_search({query?, condition?, intervention?, sponsor?, registry?, recruiting_only?, limit?}) — trials matching a free-text query (titles, conditions, interventions, with WHO synonym expansion) and/or condition / intervention / sponsor fields. Each row carries the trial id, the source registry (code and name), recruitment status, registration date, whether results are posted and the ICTRP record URL. registry keeps only one source registry (ChiCTR, CTRI, IRCT, DRKS, jRCT, CT.gov, …). A search with no matches returns total_trials: 0 with the query used.
  • ictrp_trial({trial_id}) — the full record for one trial by its registry id: source registry and its record URL, titles, primary sponsor, status, study type and design, phase, countries of recruitment, conditions, interventions, outcomes, eligibility, sample size, dates, funding sources, secondary ids, ethics review status. An id ICTRP does not know returns found: false.

Every response carries data_as_of (the time the portal was read). ICTRP itself refreshes from the registries weekly; ictrp_trial returns last_refreshed_on for the record.

Use alongside clinicaltrials (the US registry's own API, richer for NCT trials), isrctn and anzctr.

Keyless.

Data sources

The portal has no JSON API. Things the next person would otherwise rediscover:

  • Search is a WebForms postback. GET the page for its __VIEWSTATE, __EVENTVALIDATION and the ApplicationGatewayAffinity cookies, then POST the whole form back with TextBox1 + Button1=Search (basic) or the ctl00$ContentPlaceHolder1$txt… fields + btnSearch (advanced). Posting a control the page did not render (e.g. a page size on the first POST) fails event validation and 302s to /NoAccess.aspx.
  • Page size is a second postback. __EVENTTARGET=DropDownList1, DropDownList1=100 (basic) or ctl00$ContentPlaceHolder1$ddlPageSize (advanced). 100 is the maximum.
  • The advanced search renders no pager, so a field search returns at most the newest 100 trials; the response says so in note when there are more. The basic search pages with __EVENTTARGET=GridView1, __EVENTARGUMENT=Page$N; with a registry filter the tool scans up to 5 pages (500 trials).
  • The result count wording changes: "407 records for 385 trials found" vs "1 trial found". A record is one registry entry; a trial groups the entries that cite each other as secondary ids.
  • Country is not filterable. The advanced search's country filter is a two-step listbox postback and its free-text box did not change the result count when tested (stroke: 18,749 records with and without "China"). Use registry for China/Japan/India/Iran, or ictrp_trial's countries.
  • The XML/CSV export is not used. It sits behind an "I agree" to terms that restrict commercial use of the downloaded data; this pack only reads the public result and record pages.
  • An unknown trial id answers HTTP 200 with the empty record template.
  • Records include contact persons (names, addresses, phone numbers, emails), including the ethics committee's contact. The tool does not return them.
  • Edge-probed 2026-10-09 from a throwaway wrangler dev --remote Worker: GET 200, search POST 200 ("407 records for 385 trials found for: psilocybin"), record page 200. No bot challenge on any of the three.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

json
{  "mcpServers": {    "who-ictrp": {      "url": "https://gateway.pipeworx.io/who-ictrp/mcp"    }  }}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/who-ictrp/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

json
{  "mcpServers": {    "pipeworx": {      "url": "https://gateway.pipeworx.io/mcp"    }  }}

Both URLs reach the same gateway and the same 1764+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

bash
curl -X POST https://gateway.pipeworx.io/v1/tools/ictrp_search \  -H 'Content-Type: application/json' \  -d '{"condition":"stroke","registry":"ChiCTR","limit":10}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/ictrp_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

json
{  "mcpServers": {    "who-ictrp": {      "command": "npx",      "args": ["-y", "@pipeworx/mcp-who-ictrp"]    }  }}

Or run it directly to confirm it starts:

bash
npx -y @pipeworx/mcp-who-ictrp

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Who Ictrp data" })

The gateway picks the right tool and fills the arguments automatically.
