Notion display language switcher
Input
language requiredTarget display language.
Output
language requiredalreadySet requireddocLang optionaldocument.documentElement.lang after the switch, waited for until it agrees with the requested language. On the already-set path the tab may have booted from Notion's cached shell still rendering the previous locale, so it is reloaded once before the guard gives up.
Invite workspace member (Notion)
Invite someone to a Notion workspace by email, with a chosen role and built-in verification. Records the People page before and after, returning invited / verified — proof the invite actually landed. dryRun (default true) fills the invite form and cancels without sending; set it to false to actually send the invite. Role defaults to "Restricted member" (available on all plans); "Workspace owner" is also supported. The "Member" role requires a paid Notion Plus plan and is rejected up front rather than silently opening a billing/upgrade dialog. Acts on the workspace currently active in the browser, so there is no workspace name to pass. Requires being signed into Notion with permission to invite members.
Get Notion Marketplace custom agent
Fetch one Notion Marketplace custom agent by its URL slug: title, icon, brief and full description, advertised features, gallery images, categories, the integrations it requires (Notion, Slack, …), creator, install count, rating, price, published locales and last update. Read-only.
Create Notion page integration
Create an internal Notion integration scoped to a specific page and connect it to that page. Returns token, integrationId, pageId, integrationName. The token is shown only at creation, so capture it immediately.
