Dataset Join & Merge

Verified · 2 mo ago

Join two lists of JSON rows on a key, like SQL or VLOOKUP: left, inner, full, anti joins, union.

Install

claude mcp add --transport http dataset-join-merge https://dataset-join-merge.nerolabs.workers.dev/mcp

Our take

Implements SQL-like joins and unions over JSON row lists, covering common merge patterns such as left, inner, full, and anti joins. It is useful for agents doing small-to-medium structured data reconciliation where spinning up a database would be excessive. The scope is clear, but the lack of adoption signals means users should treat it as a young utility and test edge cases around keys, duplicates, and row shape.
