Quick Answer / TL;DR
The Weaviate MCP server enables AI agents to manage objects, schemas, and perform vector searches in Weaviate, an open-source vector database.
Key Takeaways
- Create, read, and delete objects
- Perform vector and hybrid searches
- Manage schemas
- Authenticates via API key
Definitive Statement: The Weaviate MCP server enables AI agents to manage objects, schemas, and perform vector searches in Weaviate, an open-source vector database.
Technical Context & Protocol Usage
- Detailed Explanation
- This server exposes tools for `create_object`, `get_object`, `search_objects`, and `delete_object`. It uses the Weaviate Node.js client and supports API key authentication. Weaviate's hybrid search (vector + keyword) provides powerful retrieval capabilities for RAG applications.
Format & Payload Metadata
Format: JSON-RPC 2.0
Latency: Depends on index size; typically 20-200ms
Real-World Implementation Use Case
An AI agent uses Weaviate to search for documents related to a user query, combining vector similarity with keyword filtering.
