Humanitarian Data Exchange (HDX) MCP — data.humdata.org, the open humanitarian-data platform run by UN OCHA on CKAN.

Part of Pipeworx — an MCP gateway connecting AI agents to 1881+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

Tool	Description
search_datasets	Search the Humanitarian Data Exchange catalogue (CKAN package_search) for datasets on displacement, refugees, food security, conflict, disasters, health, population, etc. Returns matching datasets with titles, descriptions, publishing organization, locations (groups), and resources. Filter by country/crisis with fq="groups:" (e.g. "groups:syr") — get codes from list_locations.
dataset_details	Full dataset record by id or slug (CKAN package_show), including its resources. Each resource has a "download_url"/"url" pointing at the actual data file (usually CSV/XLSX) — that is how you read the underlying rows, since HDX does not expose a keyless row query.
list_locations	List the locations on HDX (CKAN group_list) — countries and crises, each keyed by a lowercase ISO3 code (e.g. {"name":"syr","display_name":"Syrian Arab Republic"}). Use a code as fq="groups:" in search_datasets to scope results to a country/crisis.
list_organizations	List the publishing organizations on HDX (CKAN organization_list) — UN agencies and NGOs such as OCHA, UNHCR, WFP, IDMC, ACAPS. Use an org "name" as fq="organization:" in search_datasets.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/hdx/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:

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

Both URLs reach the same gateway and the same 1881+ 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

curl -X POST https://gateway.pipeworx.io/v1/tools/hdx_search_datasets \
  -H 'Content-Type: application/json' \
  -d '{"query":"displacement refugees"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/hdx_search_datasets. 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:

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

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-hdx

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 Hdx data" })

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