MCP Server - generation of images and videos using Amazon Nova models

[dvejsada]

If anyone is interested, I have created MCP Server running over SSE with tools to create images and videos using Amazon Nova Canvas (images) and Amazon Nova Reel (videos) models. You can just simply deploy it with docker.

Images are provided directly to LibreChat, video generation tool will return link to generated video in S3 bucket (as file cannot be returned from MCP and video generation takes some time).

You can check it here.

Suggestions and improvements are welcomed.

Hi @dvejsada ,
just tired it out.
It does work. Cool job.
But I have to restart the complete docker compose stack after every request to send a new request.

Any Idea whats wrong ?

Yeah, I need to update MCP python library, there was some breaking change. I will try to get to it soon.
