Turn any (CKAN) open data portal into a conversation.

Give your AI assistant direct access to any CKAN open data portal — search datasets, explore organizations, query tabular data, and read metadata, all through natural language.

CKAN is the open-source platform behind most public open data portals worldwide (Italy's dati.gov.it, the US data.gov, Canada's open.canada.ca, and many more). Navigating these portals usually requires knowing their structure, APIs, and search syntax. This MCP server removes that barrier: once connected, your AI tool can do it all for you.

This is possible because of open standards and open source. CKAN exposes a fully documented, public API. Metadata follows DCAT, an open W3C standard for describing datasets. Both are free to use, free to build on, and maintained by open communities. This server stands on that foundation.

Who is this for? Everyone. Journalists looking for data to verify a story. Researchers exploring public datasets. Public servants checking what data their administration publishes. Developers building data pipelines. No CKAN knowledge required.

Questions

What is the CKAN Server MCP server?

MCP server for querying CKAN open data portals (package search, DataStore SQL, organizations, groups, tags)

What tools does CKAN Server expose?

20 in total: 20 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is CKAN Server safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.

What credentials does CKAN Server need?

It reads CF_API_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does CKAN Server run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as ckan-mcp-server-website at 1.0.0.

How current is this page?

The grade is for one exact copy of the source (9bf40d109f73), read on 2026-10-08. The repository is watched and re-audited when it changes.
