Variable	Required	Description
`WEAVIATE_API_KEY`	Yes	Weaviate cluster API key (sent as Authorization: Bearer) Docs.

Create a Weaviate Cloud account: Sign up at https://console.weaviate.cloud - free 14-day sandbox clusters are available for testing. Self-hosted Weaviate with API-key auth enabled works too.
Create a cluster and grab credentials: Create a cluster, then open Cluster details to copy the REST endpoint URL and an API key (use a read-write key for object creation). The key is only displayed once.
Store the key and note your host: Add WEAVIATE_API_KEY=… to your .env file. Tools take the cluster host (without https://) as the clusterHost parameter, e.g. my-cluster-abc123.weaviate.cloud.
Verify access: Run the Get Schema tool with your clusterHost.

Every tool needs the clusterHost parameter - there is no global Weaviate API host
nearText GraphQL queries require a vectorizer module configured on the collection (and possibly a model-provider API key set on the cluster)
Admin keys can read and write; read-only keys will get 403 on Create Object

Tool	Access	Description
Get Schema	Read	List all collections (classes) and their property definitions
Run GraphQL Query	Read	Run a GraphQL query against the cluster (Get, Aggregate, Explore - including nearText/nearVector search)
