The single biggest thing that turns 'I should look around' into 'I'm already set up' is a one-step import of their existing `promptfooconfig.yaml`. This rides a time-limited intent window and is a product feature, so it belongs in the engine (every deployment gets it: Cloud, standalone, engine).\n\n## What\nAn importer (REST endpoint + a small UI entry point, and ideally an MCP tool) that takes a \n\n[Read the thread](https://github.com/homemade-software-inc/completion-kit/issues/76) · 2026-06-15 · closed · outside contributor · 2 comments\n\n### Most recent\n\n### MCP: no way to regrade/rerun existing run responses (rerun/retry_failures/regrade not exposed as tools)\n\n## Summary\n\nThere is no way, over the MCP surface, to **re-judge the existing responses of a completed run** — e.g. after attaching/changing metrics post-generation, or after editing a metric. `runs_generate` refuses on a completed run with:\n\n> Cannot start a run in state \"completed\".

If you instead pass `metric_group_id` — the intuitive param, since metric groups are first-class MCP objects (`metric_groups_create` / `metric_groups_get` / `metric_groups_list`) — it is **silently dropped**: no validation error, the run is created with `metric_ids: []`, generation runs to completion, and the run ends `status: \"completed\"` with `judged: 0/0` and `avg_score: null`.

Per the MCP streamable-HTTP transport, a `GET` to the MCP endpoint should either open an SSE stream (`200 text/event-stream`, for server→client messages) or return **405 Method Not Allowed** when the server does not offer server-initiated streams.
