Turn Metorial on for a conversation with the + button, then Connectors; each connector has its own toggle.
Claude asks before it runs a Elasticsearch tool. Choose Allow always only for tools you trust to run unsupervised.
Use the Search and tools menu to switch off tools you do not need in the current conversation.
Remove the connector from Customize, then Connectors. Team and Enterprise owners can do this for the whole organization.

Members on a Team or Enterprise plan cannot add the connector: On Team and Enterprise plans an Owner adds custom connectors in Organization settings, then Connectors. Members then connect it with their own account.
The Free plan only allows one custom connector: One is enough: your Metorial URL carries every app your team approves, so you never need a second connector.
Tools do not show up in a chat: Connectors are switched on per conversation. Open the + menu in the chat, choose Connectors, and turn Metorial on.
