Is nerolabs-dataset-diff-detector live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is nerolabs-dataset-diff-detector free to use?

Yes — the hub reached it with no key and no payment.

What tools does nerolabs-dataset-diff-detector have?

2 tools: diff_rows, list_capabilities.

Is nerolabs-dataset-diff-detector safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list_capabilities reads open 11h ago

  Returns the exact matching and comparison rules diff_rows uses, the shape and order of its output rows, and the maximum rows per call. Call this first if you are unsure how values are compared. Free, processes no data.

• diff_rows reads unknown never probed

  Compares two versions of the same list of JSON rows (a before and an after snapshot, such as yesterday's and today's price list, product feed or CRM export) and returns one row per difference: status added, removed or changed, the key, the old and new values, and changedFields naming exactly which fields moved. Set keyFields to the field(s) that identify a row (sku, id, email); without it rows match on full content and an edited row shows as removed plus added. Comparison is exact: "19.99" (text) and 19.99 (a number) differ, as do "Blue" and "blue " and null and a missing field; nested objects compare by value. Put always-changing fields such as timestamps in ignoreFields. The summary counts added, removed, changed and unchanged rows and warns about duplicate keys, rows missing a key, and field names found in no row. oldRows and newRows together are limited per call (list_capabilities gives the number); larger calls are refused with a message saying how to split them.
