Kernel MCP server

For the hosted MCP server and CLI interactive login, no pre-created developer app is required. Start from a client that supports Kernel's OAuth flow and complete the browser consent when prompted; Kernel publishes OAuth authorization metadata at authorization-server metadata and supports dynamic client registration at https://mcp.onkernel.com/register. For the CLI, the easiest path is `kernel login`, which opens the browser and stores refreshable credentials automatically.

Fastest non-interactive path: create or recover a key using Kernel's Auth.md flow, which emails a one-time code and returns the plaintext API key once. If you already use the CLI, you can first run kernel login, then mint and manage keys with `kernel api-keys create`; the docs also note keys can be managed from the dashboard. Store the resulting sk_... secret securely; Kernel only returns plaintext keys on create/rotate.
