Weaviate

Weaviate is an open source vector database, and its MCP server gives Notion AI access to the collections and objects in your Weaviate Cloud cluster. Ask Notion AI to inspect a collection's schema, list tenants, run hybrid vector and keyword searches, or insert and update objects when write access is turned on.

With Notion Agent

1. Select Get connection on this page.
2. Enter your Weaviate API key and approve access. You'll be asked for your Weaviate URL.
3. Ask Notion AI to use Weaviate by name.

Try asking:

• "Show the schema of my Articles collection in Weaviate"
• "Search my Products collection in Weaviate for waterproof hiking boots"
• "List the tenants in my Customers collection in Weaviate"

With Custom Agents

1. Open your agent's Settings → Tools & Access and select Add connection.
2. Choose Weaviate, enter your Weaviate API key, and pick the tools the agent can use. You'll be asked for your Weaviate URL.

MCP connections are available on Business and Enterprise plans, on web and desktop.
