Weaviate MCP server
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=trueIt listens on the same port as the Weaviate REST API at /v1/mcp, authenticates via the existing API-key flow, and respects RBAC.
Tools exposed
| Tool | Purpose | |---|---| | weaviate-collections-get-config | Inspect collection schemas | | weaviate-tenants-list | List tenants in a multi-tenant collection | | weaviate-query-hybrid | Hybrid (vector + keyword) search | | weaviate-objects-upsert | Create or update objects |

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 That implementation has been superseded by the built-in server and is no longer maintained.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.
