[FEATURE] Support multiple simultaneous Notion workspace connections in one session

Problem Statement

The Notion MCP connector authenticates to a single Notion workspace at a time. I work across two separate Notion workspaces under the same account (two businesses I run in parallel, kept in separate workspaces on purpose). To switch between them inside a Claude Code session, I have to manually disconnect and reconnect the Notion integration every time — there's no way to hold both connections live at once.

Proposed Solution

Allow a single Claude Code session to access multiple Notion workspaces at the same time — for example by letting the Notion connector be added twice, each instance scoped to a different workspace, or by supporting a per-request workspace selector so switching doesn't require a full disconnect/reconnect cycle.

Alternative Solutions

A lighter alternative: keep a single connector, but allow specifying which workspace to target per session without going through Notion's full re-authorization flow each time — e.g. a quick workspace-switch command.

High - Significant impact on productivity

MCP server integration

Use Case Example

I run two independent businesses (a delivery consulting practice, a separate strategy consulting practice, online product), each with their own dedicated Notion workspace under the same account. I work on both in parallel throughout the day. Every time I need to switch context, I have to disconnect the Notion integration from workspace A and reconnect it to workspace B, which breaks my flow and wastes time.

Additional Context

Notion account: Email.com — two workspaces used daily and in parallel from the same Claude Code account.
