Connect to Claude

Add Mobus to Claude in under a minute. No install, no API keys, nothing to run.

1. Open claude.ai (or Claude Desktop / Mobile)
2. Go to Settings from the bottom left → Connectors
3. Click Add custom connector
4. Name it Mobus and paste this URL:

https://mcp.mobus.ai/mcp

5. Start a new chat and try:

"Search for air quality datasets with a commercial license"

That's it. All 15 tools are available immediately.

What it does

Just ask your AI assistant.

"Search for air-quality datasets with a commercial license" "Preview the first 20 rows of that Zenodo dataset" "Find SEC filings mentioning climate risk" "Generate an APA citation for that Hugging Face dataset" "Check if this dataset can be used commercially" "Visualize that dataset"

Mobus fans requests out to every configured platform in parallel, checks licenses, previews data, generates citations, and traces academic lineage — failing gracefully whenever an API key is missing.

Supported platforms

<table> <tr><td valign="top">

No auth needed

• data.gov
• Zenodo
• OpenML
• UCI ML Repository
• AWS Open Data
• World Bank
• WHO GHO
• NASA Earthdata
• Eurostat
• arXiv
• Census.gov
• SEC EDGAR

Missing keys automatically skip that platform. The server never crashes.

Run locally (optional)

If you prefer to self-host instead of using the hosted version above:

git clone https://github.com/hrantvirabyan/Mobus.git
cd Mobus
npm install
cp .env.example .env   # fill in any keys you have (all optional)
npm run build

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "mobus": {
      "command": "node",
      "args": ["/absolute/path/to/Mobus/dist/main.js"]
    }
  }
}

Restart Cursor. All 15 tools appear in the chat.

Claude Desktop

Same config format, in ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows).

API keys (all optional)

Variable	For	Where
KAGGLE_USERNAME / KAGGLE_KEY	Kaggle	kaggle.com/account → API
HF_TOKEN	Hugging Face	huggingface.co/settings/tokens
GOOGLE_API_KEY / GOOGLE_CSE_ID	Google	console.cloud.google.com

get_dataset_provenance / trace_citation_graph / get_dataset_lineage

Currently degraded — depend on the Papers with Code API which has shut down.

</details>

---

Known issues

• Papers with Code API shut down post-HuggingFace acquisition — lineage/provenance/citation-graph tools return errors
• Econdb now requires a key — returns empty until support is added
• arXiv rate-limits under heavy parallel load (adapter uses 3s throttle)
