/**
 * A plugin that signs the user in to a remote MCP server (for example Notion
 * or Linear) and gives the model its tools, the way Claude Code connects to
 * MCP servers:
 *
 * - `/connect <id>` finds the server's OAuth settings, registers a client,
 *   and opens the browser (PKCE, loopback on `127.0.0.1`).
 * - The tokens stay in the credential store. The model never sees them.
 * - After sign-in, the next turn has the server's tools, named
 *   `<prefix>_<tool>` by default. `toolName` can change the names.
 *   Tools that can change data ask for approval.
 * - When the connection closes, the next turn connects again. When the
 *   server sends `tools/list_changed`, the next turn lists its tools again.
 *
 * @example
 * ```ts
 * const notion = mcpConnector({ id: 'notion', label: 'Notion', url: 'https://mcp.notion.com/mcp' })
 * ```
