# Connect Claude Desktop
> Add Agent Vault to Claude Desktop or claude.ai as a custom connector and sign in, in about 3 minutes.
Connect Claude Desktop, or Claude on the web, to Agent Vault so it can check out
and sign in for you, using only mock tokens. It takes about 3 minutes in the
app's settings. Claude can't add a connector from a chat, so there is no line to
paste.
## Before you start
* An Agent Vault account, with a card if your agent will check out. New here?
The [Quickstart](/get-started/quickstart) sets one up in about 5 minutes.
* Claude Desktop or claude.ai. On a Team or Enterprise plan, someone who can
manage connectors adds it first: see [On a Team or Enterprise plan](#on-a-team-or-enterprise-plan).
## Add the connector
In Claude Desktop, open **Settings → Connectors**. On claude.ai, open
**Customize → Connectors**.
Press **+ Add**, then **Add custom connector**. Name it **Agent Vault**, enter
this URL and press **Continue**:
```text theme={null}
https://mcp.agentvault.io/mcp
```
Claude shows the sign-in settings it detected. Press **Continue** again.
Choose **Sign in now**, and keep **Use Claude's published identity**, or choose
**Register automatically**. Don't choose **Use your own OAuth client**: no
client ID or secret is needed. Press **Add**.
## Sign in
Next to **Agent Vault** in your Connectors list, click **Connect**. Sign in on
the Agent Vault sign-in page that opens, with your Agent Vault account.
In a chat, click **+**, open **Connectors** and turn **Agent Vault** on.
Connectors are off in each chat until you turn them on.
## Choose what it may use
A new connection starts with nothing granted, so your agent can't use a card or
a login yet. Until you choose, its first tool call answers:
```text theme={null}
Choose what this app may use in Agent Vault before it can act: open the connection's page in the dashboard.
```
The connection itself appears in the dashboard only once your agent makes its
first tool call, so make that call first.
Ask your agent to call `get_token_catalog`. It answers with the message above,
and the call creates the connection.
In the dashboard sidebar, under **Vault**, click **Connected apps**. The new
connection's row shows **Choose what it may use**.
Click **Choose access**. Under **Cards** and **Logins**, pick **All**, or keep
**Only selected** and tick the ones this agent may use.
Your first connection's dialog opens with nothing ticked. After that, a new
connection's dialog opens with the choices of the connection you used most
recently, so saving it unchanged grants the same cards and logins, and the same
three switches: **Let this app create and change its own logins**, **Ask me
before every purchase from this app** and **Fill a test card instead of my
card**. Check all of them for this agent before you click **Save access**.
You can change or revoke the connection on the same page at any time. See
[Connected apps](/dashboard/api-keys#connected-apps).
## Check it works
In a chat with **Agent Vault** turned on, ask Claude to call the Agent Vault
tool `get_token_catalog`. It answers with the mock tokens for the cards and
logins you allowed, such as `av_card_1_number_u7x2k`. Your real card number
never reaches the chat.
## On a Team or Enterprise plan
On a Team plan only an owner can add a custom connector. On an Enterprise plan,
an owner or someone whose role includes managing access to Libraries can. Ask
them to add it under **Organization settings → Connectors** (**Add**, then
**Custom**, then **Web**), with the same URL and the same sign-in choices. You
then find **Agent Vault** in your Connectors list and connect it as above.
## Troubleshooting
You chose **Use your own OAuth client**. Remove the connector and add it again
with **Use Claude's published identity** or **Register automatically**.
Connectors are off in each chat until you turn them on. Click **+**, open
**Connectors** and turn **Agent Vault** on.
The connection has nothing granted yet. Follow
[Choose what it may use](#choose-what-it-may-use), then ask again.
## Next
Have Claude buy something, start to finish.
Use Agent Vault from Claude Code too.
