Weaviate MCP server

This is a helper that connects your AI assistant to Weaviate, a place where you store and search information. It is handy if your team keeps documents, notes, or past conversations in Weaviate and you want your AI to look things up or save new items for you. The old standalone version is retired; the same helper is now built into Weaviate itself, so you turn it on instead of installing it.

What this MCP server does

You ask your AI a question in plain words, like what your notes say about a topic. The AI passes that request to the Weaviate helper. The helper searches your Weaviate collections using a mix of meaning-based and keyword search, and can also look up how a collection is set up or list its tenants. Then it sends the matching items back, and your AI turns them into an answer for you. If you ask it to save something, it can also create or update an item in a collection.

• Update an existing item in a collection

Try asking your AI

• “Search my Weaviate notes for anything about the Q3 launch plan”
• “What fields does the Customers collection have?”
• “List the tenants in the Support collection”
• “Save this summary as a new item in my MeetingNotes collection”

What it gives back to you

You get answers in the chat, built from the items the helper found in Weaviate, often as a short list or summary with the matching text. When you ask about a collection's setup, you get its fields and settings in plain words. When you ask it to save or update something, it tells you that the change was made. You do not see raw technical output unless you ask for it.
