Weaviate MCP Server: Semantic Search Setup

Weaviate's built-in hybrid search — combining vector similarity with keyword filtering — makes it a strong fit for MCP retrieval tools that need more precision than pure semantic search.

Core Tools

• hybrid_search(class_name, query, alpha) — alpha tunes vector vs keyword weight
• get_object(class_name, uuid)
• add_object(class_name, properties, vector)

Schema Design

Define your Weaviate class schema before wiring up tools — the model's search quality depends heavily on which properties are indexed for keyword search versus vectorized only.
