Connect Claude

← Agents

Use a remote custom connector in Claude on the web or the Chat tab of Claude Desktop. For the Code tab, use Connect Claude Code.

Claude Free permits one custom connector. For a team, an owner must add the connector before members connect their own accounts. Remote requests run from Anthropic’s cloud, including in Desktop Chat, so use the HTTPS URL below. See Claude’s custom connector guide.
