Import + Amend via Schema in API, CLI, and MCP

The Import + Amend via Schema flow is now available across all automation interfaces: REST API, CLI, and MCP.

You can now provide a schema plus existing input data, amend rows using schema rules, and get back the full resulting dataset in your requested output format.

What Was Added​

  • REST: POST /v1/generate/amend
  • CLI: anywaydata amend --schema-file ... --data-file ... --input-format ...
  • MCP: amend_data_from_spec

All three share the same core behavior.

Behavior​

  • rowCount defaults to imported row count.
  • If rowCount is smaller, only first N rows are amended.
  • Output always returns the full resulting dataset after amendment.
  • stream is accepted for compatibility but ignored for amend operations (buffered mode only).

Cross-Format Support​

The flow supports import and export across formats, including:

  • CSV input -> tab-delimited (dsv) output
  • tab-delimited (dsv) input -> CSV output

Why This Matters​

  • You can automate the same amend workflow previously available in UI.
  • You can update existing datasets without rebuilding them from scratch.
  • You can keep the same schema-driven logic across UI, REST, CLI, and MCP.
