The pill strip from the inline-MCP work is worth more than one source, so
the MCP-specific store splits into two layers with the same UX contract
(session-scoped, capped, self-limiting, one-click with narrated
idle→working→done):
- store/composer-suggestions.ts — the bus. Draft providers register into
the existing debounced sampler; event providers push/withdraw directly.
Offerings merge (event before draft), dedupe by provider-namespaced key,
and keep reference identity on no-ops.
- store/suggestion-providers/mcp.ts — the founding provider, behavior
unchanged: directory keyword/host matching, configured-server exclusion,
one-click connect with OAuth cancel + config rollback.
- composer/suggestion-pills.tsx — the generic strip; phases and cancel
live here, action/rollback/toasts stay with the provider's invoke.
No new pills yet — this is the seam for them.
