Connect with Claude

Marque is a public remote MCP server, so add it as a custom connector. Custom connectors are available across Claude web, desktop, and supported mobile surfaces.

Add the connector

1. Open Customize → Connectors.
2. Select +, then Add custom connector.
3. Name the connector Marque.
4. Enter https://marque.at/mcp as the remote MCP server URL.
5. Leave the advanced OAuth Client ID and Client Secret fields empty.
6. Select Add, then Connect.
7. Complete AT Protocol sign-in and Marque consent in the browser.

Marque supports dynamic client registration, so a manually issued client secret is not required.

Enable it in a conversation

Use the + button beside the chat input, open Connectors, and enable Marque for that conversation. Organization-managed plans may require an owner to add or approve the connector first.

See Anthropic’s custom connector guide for plan and organization controls.
