Using Clerk's MCP and need something you know is in our dashboard, but we haven't built a tool for it yet? Now your agent can easily computer-use to find it. The browser sessions that our MCP gives to agents are read-only, no mutations allowed.
Replying to @clerk
1. Browser sessions for agents Your MCP server can hand agents a single-use link that opens a signed-in browser, so agents stop getting stalled at sign-in pages. clerk.com/changelog/2026-11-…

2. Step-up permissions for your MCP tools Your MCP server can ask for only the permissions a tool needs, when the agent calls it, without dropping access the user already approved. Setup guide: clerk.com/docs/nextjs/guides…

Bundle IDs, Team IDs, Associated Domains, entitlements. The Clerk CLI now handles all of it for iOS and macOS. Ask your agent: "Add Clerk to my iOS app using the Clerk CLI."

Run clerk init in your Xcode project, or add --starter to create a new one with Clerk already set up. clerk.com/docs/ios/getting-s…

Keeping web sessions short shouldn't mean signing mobile users out every week. Clerk now lets native sessions have their own maximum lifetime. Set the lifetime that fits each platform, from 5 minutes to 10 years.

Ask your agent: "Set my Clerk app's native session lifetime to 90 days and keep web sessions at 7 days." Custom session lifetimes for native apps are now in Clerk. clerk.com/changelog/2026-11-…

Sometimes your users just need to update. Set a minimum version for your iOS and Android apps with Clerk, and anyone below it gets an update screen that links to the App Store or Google Play. They're still signed in when they come back.

Set it per app, so iOS and Android can each have their own minimum. Clerk's SDK shows the update screen for you, so there's no UI to build. Tell your agent: "Set the minimum version of my iOS and Android apps in Clerk to the current release." clerk.com/changelog/2026-11-…

2. Personal Agent Protocol (Poppy) support We know you need to meet agents where they’re at, regardless of protocol. Two weeks ago, @meta, @Instinct, @Stripe, @Shopify, @Walmart, & @SierraPlatform launched the new Personal Agent Protocol (Poppy) for agents, so we began adding support right away. Today, it’s in private beta. Reach out for access: clerkdev.notion.site/11dd8ea…

Clerk Components 2.0 starts with an experimental <UserButton /> that brings account and organization switching into one menu. Switch accounts, manage organizations, and accept invitations. @kylemac walks through the new experience and API ↓
