# Weaviate

> Connect Weaviate to your workflows: 14 operations across 3 categories.

The Weaviate node adds Weaviate operations to your workflows. Add it on the canvas or ask the AI builder for it by name, then pick an operation and fill in its fields.

<Note>
  You can wire the Weaviate node into an AI agent as a tool provider: the agent calls the operations you allow. See [Agent tools](/agents/tools).
</Note>

## Credentials

Connect Weaviate under **Credentials** in the node settings. See [Connecting credentials](/credentials/connecting) for the general flow.

Enter the values manually when creating the credential.
