The single entry point for every bulk operation on a playtable. Async: the created row is the progress handle: poll get_playtable_run with include progress every ~5s until progress.state is finished or cancelled.

type branches the body. enrich is the only paid type (action columns over the scope; a formula column never runs, it fills through backfill_playtable_field): always estimate_playtable_run first, tell the user the cost range and set max_budget to its cost_max (exhaustion auto-cancels, reason budget_exhausted; a cap at cost_expected cancels a row short); params force_rerun re-queues done cells (re-charge consent), params cells not_run | error narrows to those. export writes the scope to CSV (params format csv, a file_url) or an external tool (write_tool_sid). import batch-promotes a data source (params data_source_sid, no scope). bulk runs tag, field, workflow, move and delete edits (params operation).

scope, required for enrich, export and bulk: one form, object_sids or view_sid/filter; an empty filter is rejected, the scope is snapshotted at create; hand-picked object_sids and exclude_object_sids are capped at 10 000 each (422 scope_too_large). 409 conflict when a field already has an active run (its sid in error.context), 429 at the team concurrency cap; already_exists is always false. When NOT: single-cell fixes (update_playtable_field_value); continuous source syncing (data sources; import here is a one-shot promotion).

Contract:

• MCP tool create_playtable_run, registry package mcp.playtables/playtable_runs, mount playtables.columns.
• Operation create, response envelope create.
• Flags: none.
