MCP RAG Server
Planned integration to support Hugging Face embedding models, enabling use of community models for embedding generation.
Provides integration with OpenAI's embedding models (text-embedding-3-small) for generating vector embeddings used in semantic search and RAG workflows.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCP RAG ServerSearch my documents for information about vector embeddings."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
