MongoDB Atlas Vector Search plugin for Genkit.

Registers a retriever and indexer named mongodb/<collectionName> for each configured collection, backed by an Atlas Vector Search index. Requires MongoDB Atlas or the mongodb/mongodb-atlas-local Docker image (a plain MongoDB server does not support $vectorSearch).

Example usage:

 Genkit genkit = Genkit.builder()
     .plugin(GoogleGenAIPlugin.create(apiKey))
     .plugin(
         MongoPlugin.builder()
             .connectionString("mongodb://localhost:27017/?directConnection=true")
             .addCollection(
                 MongoVectorStoreConfig.builder()
                     .collectionName("films")
                     .embedderName("googleai/gemini-embedding-001")
                     .dimension(768)
                     .createIndexIfNotExists(true)
                     .build())
             .build())
     .build();
