Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ckan": {
      "command": "npx",
      "args": [
        "-y",
        "@aborruso/ckan-mcp-server"
      ],
      "env": {
        "CKAN_ALLOWED_DOMAINS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add ckan --env CKAN_ALLOWED_DOMAINS=your-value -- npx -y @aborruso/ckan-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ckan": {
      "command": "npx",
      "args": [
        "-y",
        "@aborruso/ckan-mcp-server"
      ],
      "env": {
        "CKAN_ALLOWED_DOMAINS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "ckan": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "CKAN_ALLOWED_DOMAINS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Ckan MCP Server safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.138) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

CKAN MCP Server

*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.

Adopted by AgID — This project has been reused by AgID, Italy's Agency for Digital Italy, as part of its effort to make public open data more accessible, immediate, and easier to consult through AI.

Two ways to use it — pick the one that suits you:

	Option A: Install locally	Option B: No install
How	`npm install -g @aborruso/ckan-mcp-server`	Point your tool to the hosted HTTP endpoint
Best for	Runs on your machine, works with any local tool	Quick start, zero setup
Request quota	No shared quota	100k requests/day shared quota

Hosted endpoint: https://ckan-mcp-server.andy-pr.workers.dev/mcp

Recommendation: Option B is a great way to get started and try things out without any setup. Once you're familiar with what the server can do, switching to Option A (local install) gives you unlimited usage with no shared quotas.

License: MIT — see LICENSE for complete details. Third-party notices: NOTICE.md.

⚖️ Limits

The local and hosted server use the same tool and output caps. The hosted endpoint also has the shared request quota shown above.

Area	Default	Maximum or configuration
Tool output	50,000 characters	Fixed server-wide cap
`ckan_datastore_search` rows	100	32,000 (`0` returns column names only)
`ckan_package_search` results per page	10	1,000
`ckan_find_relevant_datasets` results	10	50
Injected `sparql_query` rows	25	1,000 when injected; a query that supplies its own `LIMIT` is not capped
`ckan_tag_list` results	100	1,000
`ckan_find_portals` results	10	50
HTTP response body	32 MiB	`CKAN_MAX_RESPONSE_BYTES` for local Node.js deployments
Decompressed response body	64 MiB	`CKAN_MAX_DECOMPRESSED_BYTES` for local Node.js deployments

Text and Markdown responses that exceed the output cap are cut and include a truncation note. JSON responses stay parseable: the server reduces known result arrays and flags the response with _truncated and _original_count, and if a response still cannot fit it is replaced by a small object carrying _truncated and an explanatory _error. The same capped payload is sent on both channels, so a client reading structuredContent sees exactly what the text shows, truncation flags included. Use pagination or a narrower query when you need the complete result set.

🔌 Use it in your favorite tool

This server works with any MCP-compatible client. The sections below cover some of the most popular ones — if your tool isn't listed, check its documentation for MCP configuration and use the same endpoint URL or command.

All examples below work with both the local installation and the hosted endpoint. Where both options differ, both are shown.

Using local installation? You need to install the server first — see Run locally.

Using the hosted endpoint (no install) — via config file:

Configuration file location:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

"mcpServers": { "ckan": { "url": "https://ckan-mcp-server.andy-pr.workers.dev/mcp" } } }

Using local installation:

"mcpServers": { "ckan": { "command": "npx", "args": ["@aborruso/ckan-mcp-server@latest"] } } }
