How to Set Up and Use Mobus
Mobus is a dataset discovery and analysis MCP server that provides unified access to 20+ data platforms — including Kaggle, Hugging Face, data.gov, Zenodo, OpenML, World Bank, NASA, and more — through a single connector. It exposes 15 tools covering dataset search, preview, quality assessment, license checking, citation generation, lineage tracing, and visualization, making it the fastest way to give Claude the ability to find, evaluate, and cite research datasets without switching between platforms.
Prerequisites
- Node.js 18 or later installed
- An MCP-compatible client: Claude Desktop, Cursor, or claude.ai
- Optional API keys for extended access: KAGGLE_USERNAME and KAGGLE_KEY (kaggle.com), HF_TOKEN (huggingface.co), GOOGLE_API_KEY and GOOGLE_CSE_ID (console.cloud.google.com), SOCRATA_APP_TOKEN (dev.socrata.com)
Add the Mobus connector directly in claude.ai (fastest path)
If you use claude.ai, add Mobus as a custom connector in Settings > Connectors — no installation required.

https://mcp.mobus.ai/mcpOr clone and build for local self-hosted use
Clone the Mobus repository, install dependencies, copy the environment template, and build the project.
git clone https://github.com/hrantvirabyan/Mobus.git
cd Mobus
npm install
cp .env.example .env
npm run buildConfigure optional API keys for authenticated platforms
Edit the .env file to add API keys for platforms that require authentication. All keys are optional — unauthenticated platforms (data.gov, Zenodo, OpenML, etc.) work without any keys.

"mcpServers": {
"mobus": {
"command": "node",

}Restart your MCP client and test dataset search
Restart Claude Desktop or Cursor and ask Claude to search for a dataset to confirm the 15 Mobus tools are available.

Example prompts that use Mobus tools for dataset discovery, evaluation, and citation.
- "Search for air quality datasets with a commercial license"
- "Preview the first 20 rows of that Zenodo climate dataset"
- "Generate an APA citation for the Hugging Face dataset I just found"
- "Check if this Kaggle dataset can be used in a commercial product"
- "Compare these two datasets on sample size, license, and data quality score"
- "Trace the lineage of this dataset to find its original source"Troubleshooting Mobus
Kaggle searches return no results or fail with authentication errors
Set KAGGLE_USERNAME and KAGGLE_KEY in your .env file. Obtain these from kaggle.com > Account > API > Create New Token. The downloaded kaggle.json file contains both values.
Server fails to start with 'Cannot find module dist/main.js'
Run 'npm run build' inside the Mobus directory to compile the TypeScript source. The dist/ folder is not included in the repository and must be generated locally.
Google Dataset Search returns no results
Google Dataset Search requires both GOOGLE_API_KEY (from console.cloud.google.com with Custom Search API enabled) and GOOGLE_CSE_ID (from programmablesearchengine.google.com). Both must be set correctly — the API key alone is insufficient.
