About
An MCP Server to connect to your Weaviate collections as a knowledge base as well as using Weaviate as a chat memory store.
README
This standalone server is deprecated. The Weaviate Model Context Protocol (MCP) server is now built into Weaviate itself — there is nothing to install or run separately.
Use the built-in MCP server
Weaviate ships an MCP server inside the main weaviate/weaviate binary, available as a preview from v1.37.1 onward. Enable it with a single environment variable:
MCP_SERVER_ENABLED=true
It listens on the same port as the Weaviate REST API at /v1/mcp, authenticates via the existing API-key flow, and respects RBAC.

About this repository
Earlier versions of this repo contained a standalone Go implementation of an MCP server that wrapped the Weaviate REST API. That implementation has been superseded by the built-in server and is no longer maintained. The history is preserved in git for reference; for the previous source, see the commits before this notice.
