Connect Meta Muse

Connect Meta Muse to Agent Vault so it can check out and sign in for you, using only mock tokens. It takes about 2 minutes, and you set it up by asking Muse in the chat.

Copy the line for Meta Muse from your dashboard, paste it into Muse, and sign in.

Before you start

An Agent Vault account, with a card if your agent will check out. New here? The Quickstart sets one up in about 5 minutes.
Meta Muse, with custom connectors available on your account.

Paste one line (recommended)
Set it up by hand

Paste this into Muse

Read https://mcp.agentvault.io/skill.md and follow it to connect Agent Vault. Sign-in uses dynamic client registration, so no client ID or secret is needed.

Muse reads the connect skill and creates a custom connector called Agent Vault. The second sentence matters: without it, Muse may ask you to create an app and type in a client ID and secret. You don’t need either.

Muse shows a sign-in link for the connector. Open it and sign in on the Agent Vault sign-in page, with your Agent Vault account.

Ask Muse to add the connector

Send Muse this message:

Create a custom connector called Agent Vault for the MCP server at `https://mcp.agentvault.io/mcp`. It uses MCP OAuth with dynamic client registration: the connector registers itself, so don't ask the user for a client ID, client secret or redirect URI, and don't ask them to create an app anywhere. The protected resource metadata is at `https://mcp.agentvault.io/.well-known/oauth-protected-resource`, and it links to the authorization server's metadata, which has the `registration_endpoint`.

Muse shows a sign-in link for the connector. Open it and sign in on the Agent Vault sign-in page, with your Agent Vault account.

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:

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.

Make a first call

Ask your agent to call get_token_catalog. It answers with the message above, and the call creates the connection.

Open Connected apps

In the dashboard sidebar, under Vault, click Connected apps. The new connection’s row shows Choose what it may use.

Pick its cards and logins

Click Choose access. Under Cards and Logins, pick All, or keep Only selected and tick the ones this agent may use.

Check the choices, then click Save access

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.

Check it works

Ask Muse 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.

Troubleshooting

Muse asks for a client ID, client secret or redirect URI

You don’t need any of them: the connector registers itself. Tell Muse that sign-in uses dynamic client registration, or send the message from Set it up by hand, which says so in full.

The first tool call says to choose what this app may use

The connection has nothing granted yet. Follow Choose what it may use, then ask again.

Your first checkout

Have Muse buy something, start to finish.
