Retrieval requires very large dependencies

I've attempted to create an MCP server using AWS Lambda with graphrag libraries. I've used the Lambda layers instead of docker containers for lower cold-start times. However the dependencies required for graphrag are extremely large that they cant even fit into AWS Lambda layers and hit limits. **Spacy** alone is 500 MB and **llama-index-core** brings a large amount of dependencies. It would be great to be able to make the retrieval a lot more light-weight for environments like AWS Lambda.
