# Claude Web Setup

Official source: https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp

Claude web connects to Core through a custom connector in Claude settings. Claude's cloud service must be able to reach the MCP server over public HTTPS.

Core MCP server URL:

```text
https://core.gradien.ai/mcp
```

## Setup

1. Open Claude in your browser.
2. Open Settings or Customize.
3. Go to Connectors.
4. Choose Add custom connector.
5. Enter name: `Core`.
6. Paste `https://core.gradien.ai/mcp`.
7. Approve the Core login or permissions screen.
8. Start a fresh Claude chat if the connector does not appear in the current chat.

For Team or Enterprise plans, an Owner may need to add the connector under Organization settings first. Members can then connect Core individually from their own Claude connector settings.

## Optional CLI Signup

The Core setup CLI can create or link your Core account before you add the connector:

```bash
npx -y @gradien/core-agent-setup install --base-url https://core.gradien.ai --yes --harness claude-web
```

This CLI step is optional for Claude web. The key setting in Claude is still the remote MCP URL above.

## Troubleshooting

If Claude shows `Authorization with the MCP server failed`, check the Core troubleshooting page. Common causes include OAuth metadata, dynamic client registration, redirect URI allowlists, token scopes, or token audience/resource mismatch.
