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
  1. 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.

Tools

Discovery
  • search_datasets — search all 20 platforms at once
  • find_research_datasets — datasets used in papers
  • find_similar — datasets similar to one you have
Evaluation
  • get_dataset_details — full metadata
  • preview_dataset — first N rows
  • compare_datasets — 2-5 side by side
Quality & Compliance
  • assess_quality — missing values, duplicates, stats
  • check_license — commercial / academic / internal
  • check_compatibility — schema match against yours
Citation & Output
  • generate_citation — APA, BibTeX, Chicago
  • visualize_dataset (Only works locally - ask Claude to generate an artifact). — interactive ECharts dashboard
  • watch_query — monitor for new datasets
Advanced Research
  • get_dataset_provenance — introducing paper & history
  • get_dataset_lineage — variants & derivatives
  • trace_citation_graph — citation chain analysis

Supported platforms

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
  • Crossref
  • Harbard Dataverse

Optional auth

  • Hugging Face (faster w/ token)
  • Socrata (faster w/ token)
  • Semantic Scholar

Requires key

  • Kaggle
  • Google Dataset Search

Degraded

  • Papers with Code (API shut down)
  • Econdb (now requires key)

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
SOCRATA_APP_TOKEN Socrata dev.socrata.com/register

Tool reference

search_datasets

Parameter Type Default Description
query string required Search query
sources string[] all Platforms to include
limit number 5 Results per source (max 20)
license string — e.g. cc-by-4.0
format string — e.g. csv, parquet
updated_after string — ISO date
modality string — e.g. tabular, image

get_dataset_details

Parameter Type Description
source string Platform
dataset_id string Dataset ID

preview_dataset

Parameter Type Default Description
source / dataset_id string required —
rows number 10 Max 100

visualize_dataset (Only works locally - ask Claude to generate an artifact)

Generates an interactive ECharts dashboard with column picker, filter builder, row range selector, 9 chart types, sortable table, and PNG/SVG/CSV/JSON export.

Parameter Type Default Description
source / dataset_id string required —
rows number 200 Max 500
open boolean true Auto-open browser

compare_datasets

Parameter Type Description
datasets array 2-5 {source, dataset_id} objects

check_compatibility

Parameter Type Description
source / dataset_id string —
schema array [{name, type?}]

find_similar

Parameter Type Default Description
source / dataset_id string required —
limit number 5 Max 20

generate_citation

Parameter Type Default Description
source / dataset_id string required —
format string apa bibtex, apa, chicago

assess_quality

Parameter Type Default Description
source / dataset_id string required —
sample_rows number 100 Max 500

check_license

Parameter Type Description
source / dataset_id string —
use_case string commercial / academic / internal / redistribution

watch_query

Parameter Type Description
action string add / remove / list / check
query / sources / watch_id — See action

find_research_datasets

Parameter Type Default Description
query string required Research topic
limit number 10 Max 20
semantic boolean false SPECTER v2 embeddings

get_dataset_provenance / trace_citation_graph / get_dataset_lineage

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

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)
