In-conversation MCP authorization and message queues

Connecting external MCPs is now part of the conversation itself, instead of a separate setup step. When an agent needs access to a tool, it can prompt the user to connect it right at that moment and then continue the original request once access is granted. This makes the experience feel much more natural and reduces the friction of getting started with tool-powered workflows.

We also introduced session-level tool access, so connected tools are available only where they are relevant. That gives users a clearer sense of control over what an agent can use during a conversation, while helping keep tool usage focused on the task at hand.

Conversation queue

We also improved how conversations behave when several messages arrive quickly. Messages are now processed in order, one at a time, instead of competing in parallel. This creates a more predictable experience in fast-moving chats and helps reduce confusing or out-of-sequence responses.

Each queued message gets its own ⏳ indicator, and the indicator is removed when the message is processed.
