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.

Questions

What is the Mobus MCP server?

Search, preview, and analyze datasets from 20+ platforms via a single MCP connector. Works with Claude instantly.

What tools does Mobus expose?

13 in total: 12 read-only, 0 that write, and 1 that can delete or overwrite (watch_query). Every one is listed on this page with its risk.

Is Mobus safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Mobus need?

It reads DATAVERSE_API_TOKEN, GITHUB_TOKEN, GOOGLE_API_KEY, HF_TOKEN, KAGGLE_KEY and SOCRATA_APP_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Mobus run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as mobus at 2.1.0.

How current is this page?

The grade is for one exact copy of the source (8340a17af00c), read on 2026-10-08. The repository is watched and re-audited when it changes.
