Array Dedupe removes duplicate values from arrays, returning only unique elements in their original order. Use via MCP in Cursor or Windsurf, or call GET /v1/array/dedupe with your array data. Perfect for cleaning datasets before analysis — handles strings, numbers, and mixed types deterministically without the ambiguity of LLM-generated deduplication logic.

}Array Dedupe keeps the first occurrence of each unique value and removes subsequent duplicates, maintaining the original sequence of first appearances.
Yes, it handles mixed types by comparing values exactly — '5' (string) and 5 (number) are treated as distinct elements.
Use the 'array_dedupe' MCP tool in Cursor, Claude Code, or other supported editors to remove duplicates from arrays in your code.
It works with any JSON-serializable data including nested objects, comparing them by their complete structure and content.
TinyFn's implementation handles edge cases consistently across all data types and provides guaranteed deterministic results, unlike ad-hoc deduplication logic that might miss corner cases.
