How to connect multiple Kit accounts to Claude

Claude's built-in Kit connector works well if you use one Kit account. But when you connect a second account, it replaces the first.

If you manage separate Kit accounts for different products, regions, or business units, that quickly becomes frustrating.

Composio fixes this by keeping each Kit account separate and giving it a simple name, such as kit-1, kit-2, or kit-3. Claude can then use the right Kit account when you mention that name.

• One Composio connector in Claude
• Two or more Kit accounts connected behind it
• A clear name for each account
• The ability to work in the right Kit account from a single Claude chat

For example:

Search my kit-1 and kit-2 Kit accounts for anything that needs my attention from the last 7 days. Tell me which account each item came from.

Using the kit-1 account, add new subscriber to my welcome form.

• A Claude account
• A free Composio account
• Access to each Kit account you want to connect

If you use Claude Free, you can have one custom connector. If you already use that slot, you will need to remove the existing custom connector first.

If you use Claude Team or Enterprise, an Owner may need to add the connector for the organisation. Each member can then connect their own accounts.

Step 1: Add Composio to Claude (one-time process)

1. Click the button below. This will take you to the Claude Custom Connector modal.

Add to Claude

2. Click Continue

3. In the next modal, click Add

4. It will take you to the authentication page. Sign in to Composio and approve the connection.

Then return to Claude and make sure Composio is enabled.

Step 2: Connect your first Kit account

In a new Claude chat, type:

Connect my kit-1 Kit account to Composio. Call it kit-1.

Claude will give you a sign-in link.

1. Click the link.
2. Sign in to your kit-1 Kit account.
3. Review and approve Kit's permission request.
4. Return to Claude.

Claude should confirm that the account is connected.

The name kit-1 is how Claude knows which Kit account to use. Choose short, obvious names. Good examples include:

• kit-1
• kit-2
• kit-3

Step 3: Connect your second Kit account

In the same Claude chat, type:

Connect another Kit account. Call it kit-2.

Claude will give you a new sign-in link.

1. Open the link.
2. Sign in to the second Kit account.
3. Review and approve Kit's permission request.
4. Return to Claude.

Claude should confirm that kit-2 is connected.

Important: Check that Kit is showing the second account before you approve access. If the wrong account appears, sign out or open the link in an incognito or private window.

Repeat this step for every other Kit account you want to add. Give each connection a short, descriptive name such as kit-1, kit-2, kit-3, or client-acme.

Step 4: Check your connected Kit accounts

Ask Claude:

List my connected Kit accounts in Composio. Show each account's name and connection status.

You should see every account you added, and each connection should show as ACTIVE.

For an extra check, ask:

Show the account email or ID and the account name for each connected Kit account.

This helps you confirm that every label points to the correct Kit account and that you did not connect the same account twice.

Step 5: Use the right Kit account

Mention the account name whenever you ask Claude to work with Kit. This is especially important when an action could change data.

Review activity across accounts

Check kit-1 and kit-2 for anything new in Kit from the last 14 days. Group the results by account.

Create a custom field for subscriber notes

Using the kit-1 account, create a custom field for subscriber notes.

Create a tag called 'VIP' for top customers

Using the kit-2 account, create a tag called 'VIP' for top customers.

Find something across accounts

Search all connected Kit accounts for customer@example.com. Show which account it appears in and summarise the latest activity.

For actions such as creating, changing, or deleting data, ask Claude to show you the planned action first and wait for your confirmation.

Add this to your Claude preferences or project instructions, replacing the examples with your own account names:

My Kit accounts are: kit-1 = my main account, kit-2 = my second account, and kit-3 = a client account. Always use the named account when I specify one. If I do not name an account, ask me which one to use. Before creating, changing, or deleting anything, show me the planned action and wait for confirmation.

If Claude's built-in Kit connector is also enabled, Claude may use it instead of Composio. For a clearer setup, turn off the built-in connector or explicitly tell Claude to use Kit through Composio.

The chat method is the quickest way to connect accounts. Use the dashboard when you want to add, rename, reconnect, or remove a connection.

1. Go to dashboard.composio.dev.

2. Sign in with the same Composio account you connected to Claude.
3. Open For You from the product switcher.
4. Find Kit.
5. Click Connect and complete the Kit authorisation flow.
6. Click Connect again to add another Kit account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as kit-1, kit-2, or kit-3.

If Kit opens the wrong account during authorisation, sign out first or use an incognito or private window.

From the dashboard, you can also:

• Rename a connection when a default label such as kit-2 is no longer useful.
• Disconnect or delete an account you no longer want Claude to access.
• Re-authorise an expired or revoked connection.
