How to Connect Multiple Notion Workspaces to Claude Cowork
A Notion authorization covers exactly one workspace, and Claude holds one Notion connection. Connect every workspace to Carly, add Carly to Claude once, and a single Cowork task can read or write in whichever workspace you name. Carly holds your Gmail and Outlook mailboxes and every calendar on both sides in the same place.
What the finished setup gives you
With one Carly connector in Cowork, you can:
- search two or more Notion workspaces in one task;
- compare a client’s tracker against your own roadmap;
- create a page in the workspace you name, not the last one authorized;
- comment on a client page while writing the summary into your own wiki;
- build one status brief from every workspace you hold;
- keep the routing intact across a long unattended run.
The workspaces stay separate underneath. Carly supplies the routing, and Claude remains where you run the task.
Why the native Notion connector does not solve this
Notion’s own wording is unambiguous. After you authorize with OAuth, the client can use Notion MCP tools on content you can access in the selected Notion workspace, and the token exchange returns a single workspace id. Notion’s connection screen says connections are workspace-specific, and that you switch by clicking the workspace name at the top right.
Whether Claude stores a second Notion token beside the first or replaces it is not documented by either vendor, so do not plan around an answer. Two signals lean the same way without settling it: the Notion connector’s sample prompt in Anthropic’s directory is “Which Notion workspace am I currently connected to?”, and Notion’s own agent product answers the same question about itself by saying not within a single agent, with multiple accounts needing separate agents.
One scope surprise worth knowing, because most people arrive with the wrong model. The older API-style connection let you add pages to an integration one at a time. The connector Cowork uses is Notion’s MCP server, and Notion states that MCP tools act with your full Notion permissions and reach everything you can reach. Connecting is not a narrowing step.
1. Sort your workspaces
The people below are fictional.
| Workspace | Your access | Native path |
|---|---|---|
| Company wiki, all teamspaces | Member of your workspace | Yes |
| A project database you were added to | Same workspace | Yes, same connection |
| A client workspace at Databricks | Guest on some pages | Not in the same connection |
| Your personal notes workspace | Second workspace you own | Not in the same connection |
| A second employer’s workspace at Adobe | Member, separate workspace | Not in the same connection |
The first two are covered the moment you connect. The rest are the reason for the steps below. Notion adds guests per page rather than per workspace, so a guest connection reaches exactly the pages shared with it.
2. Connect the first workspace to Carly
- Sign in at carlyassistant.com.
- Open carlyassistant.com/integrations.
- Find Notion and click Connect.
- Authorize the first workspace, checking the workspace name before you approve.
- Confirm it appears in Carly’s connected list.
3. Add every other workspace
- Return to Carly’s integrations page.
- Select Notion → Connect again.
- Switch workspace on Notion’s authorization screen using the name at the top right.
- Complete authorization.
- Confirm the workspace name before adding another.
Give each one a label you will actually use, such as Company, Personal, and Databricks. The labels are what routing hangs on later.
4. Connect Carly to Claude Cowork
In Claude:
- Open Customize in the sidebar.
- Select Connectors.
- Click +, then Add custom connector.
- Paste
https://carlyassistant.com/mcp/. - Click Add and authorize your Carly account.
- In the Cowork task, open + → Connectors and enable Carly.
Anthropic documents this path in its remote MCP connector guide. Custom connectors are available on free, Pro, Max, Team, and Enterprise, with free users limited to one. On Team and Enterprise an Owner may need to add it before members can connect.
5. Test each workspace read-only
One workspace per prompt until routing is reliable:
In the Company workspace, list every page in the Engineering teamspace edited in the last seven days, with who edited it. Do not change anything.
In the Databricks workspace, find the delivery tracker and tell me which rows are still marked Blocked. Read only.
Then the cross-workspace question that was not possible before:
Search Company and Databricks for pages mentioning the Q4 migration and show which workspace each result came from.
6. Reuse this routing prompt
Treat my main workspace as Company, my private workspace as Personal, and the client workspace as Databricks. Always state the target workspace before creating, updating, moving, or commenting on a page. Never write to a workspace I have not named.
Then name the target on every action:
Create the retro page in Company under Engineering, and add a comment on the Databricks delivery tracker linking to it.
Native Notion connector versus Carly
| Need | Notion connector in Cowork | Carly connector |
|---|---|---|
| Read pages and query databases | Yes | Yes |
| Create and update pages, comments and views | Yes | Yes |
| Search beyond your workspace | Only with Notion AI access | Not applicable |
| Hold several Notion workspaces at once | Not documented, treat as one | Yes |
| Answer one question across two workspaces | No | Yes |
| Start when a page or row changes | No | Yes |
The trigger row is the sharp one. Notion does emit events: webhooks fire on page created, page content updated, page properties updated, database content updated, and comment created. They go to an endpoint you run, and Cowork cannot subscribe to any of them. What Cowork has instead is a clock, running hourly, daily, weekly, on weekdays, or manually. A status flipping to Ready For Review at 09:40 waits for the next scheduled run.
Carly holds several workspaces at once, routes each read and write to the one you name, and subscribes to the events Notion already emits. Carly offers free Zapier-style workflows; AI agents start at $35/month.
Quick fixes when a workspace does not appear
| Problem | Fix |
|---|---|
| Claude answers about the wrong workspace | Ask which workspace it is connected to, then route through Carly by name |
| Search returns nothing outside Notion | Search beyond your workspace needs Notion AI access |
| A client page is invisible | Guests are added per page, so only shared pages are reachable |
| Claude keeps pausing before writing | Auto mode leaves write and delete tools to Claude, and Team or Enterprise policy may require per-task approval |
| An Enterprise admin blocks the app | Notion Enterprise can restrict members to an approved list of AI apps |
Frequently asked questions
Can Claude Cowork connect to two Notion workspaces?
Not as a documented feature. A Notion authorization returns a single workspace id, and Notion’s connection screen says connections are workspace-specific. Connecting each workspace to Carly is what makes several reachable from one task.
Does the Notion connector work in Cowork or only in chat?
It works in Cowork. Anthropic states that web connectors are available across Claude, Cowork, Claude Desktop, and Claude Mobile, and Cowork’s documentation says connector permissions behave the same as in chat.
Can Claude edit my Notion pages, or only read them?
It can edit. Notion’s MCP server exposes creating pages, updating, moving and duplicating pages, creating databases and views, and creating comments.
Do I choose which Notion pages Claude can see?
No, and this catches people out. MCP tools act with your full Notion permissions and reach everything your account can reach. Scope it by connecting an account that only holds the access you want to expose, such as a guest account on a client’s pages.
Does Cowork run something when a Notion page changes?
No. Notion emits webhook events for page and database changes, but those go to your own endpoint and Cowork cannot subscribe to them. Cowork’s unattended runs are scheduled hourly, daily, weekly, or on weekdays.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
