## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? Docs update for the MCP cost confirmation launch ([AI-1161](https://linear.app/supabase/issue/AI-1161/write-the-docs)). ## What is the current behavior? The MCP server guide lists `get_cost` / `confirm_cost` but doesn't describe the elicitation-based cost confirmation flow that `@supabase/mcp-server-supabase` 0.12.0 introduces for `create_project` and `create_branch` on form-capable clients. ## What is the new behavior? - New **Cost confirmation** section in the MCP server guide: how the elicitation flow works (accept / decline / expiry / rate-change outcomes, all side-effect-free except accept), the zero-cost skip, client support, and how to tell which cost flow a connection uses. - New troubleshooting entry: "Cost confirmations do not appear in your MCP client". - Three `supa-mdx-lint` dictionary additions the new prose needs (`elicitation(s)`, `dialogs`, `pauses`). ## Additional context **Draft — hold until launch.** Merge gates before publishing: 1. The feature is enabled for hosted connections. 2. The client support table is re-verified against launch verification results (there's a matching `{/* ... */}` reviewer note above the table). Client support moves quickly; the table reflects verification as of 2026-09-04. Needs review: - **Rate-change behavior follows the shipped code, not the spec docs**: on any change to the computed cost between confirmation and creation (including a decrease), the server reissues a fresh confirmation rather than proceeding (`account-tools.ts` redemption path in supabase/mcp). Flagging in case the intent was lower-or-equal proceeds. - No exact confirmation expiry is stated because the TTL is deployment-configured (`ttlSeconds`). - Wording deliberately says "client-mediated" style confirmation and avoids claiming a person approved each action, since clients can answer elicitations via hooks. Test plan: `supa-mdx-lint` clean on both files; Prettier (repo config) clean. No runnable snippets, so no sandbox verification needed.

Available options depend on connection scope, enabled features, and read-only settings. * The configuration panel explains when skip selections are unavailable or ignored by certain client configurations. * **Documentation** * Added guidance on cost and SQL confirmation prompts, Edge Function secret entry, and troubleshooting missing prompts or unavailable secret collection. This includes client requirements, fallback behavior, and relevant security considerations. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> Co-authored-by: Barry Roodt <barry.roodt@supabase.io>
Supabase UI Patterns
This package should be used for components which are built using NPM libraries (react-markdown, reactflow for example),
which make no sense to be included in all apps. It should also be used for components which are constructed using various
components from the ui package.
This package does not have a barrel file - each component has to be imported from its index
(ui-patterns/PrivacySettings, for example). This is intentional so that adding a new component which is used only in
1 or 2 apps doesn't burden the rest of the apps.
