Claude.ai and Claude Desktop connectors reads its MCP servers from null under the null key. There is no config file here: the Add custom connector form asks for a name and a Remote MCP server URL, with an Advanced settings section for an optional OAuth Client ID and Client Secret. No restart. Click Connect once the connector is added, then turn it on for a conversation from the + button, Connectors.
| Scope | Path |
|---|---|
| Individual, Pro or Max | Customize (claude.ai) or Settings (Claude Desktop), Connectors, the + button, Add custom connector |
| Team or Enterprise | an Owner or Primary Owner adds it once at Organization settings, Connectors, Add, Custom, Web; members then click Connect on it from Customize, Connectors |
On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.
