01 · Install Ckan MCP Server

before you install - you'll need

CKAN_ALLOWED_DOMAINS is optional or environment-specific per the README.

Claude Code

claude mcp add ondata-ckan-mcp-server -- npx -y @aborruso/ckan-mcp-server

Claude Desktop / Cursor / VS Code - add to config

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

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @aborruso/ckan-mcp-server - the @aborruso scope differs from the repo owner (ondata); confirm it's the project's official package

registry registry publisher io.github.aborruso is not the repo owner (ondata) - the registry entry was published by someone else
