## Description

MCP-Chroma is a server implementation that provides AI assistants with direct access to ChromaDB vector database capabilities for semantic search and document management. Developed by viable, this Rust-based server exposes ChromaDB operations through standardized tools for creating and managing collections, adding and retrieving documents, and performing similarity searches with customizable parameters. The implementation includes configuration options for different client types (HTTP, cloud, persistent, or ephemeral) and handles environment variable management, making it particularly useful for applications requiring vector embeddings storage, retrieval, and semantic search functionality without implementing alternative solutions.
