chroma-core/chroma-mcp
Chroma MCP Server is an implementation of the Model Context Protocol (MCP) designed to provide database capabilities for Chroma, an open-source embedding database optimized for managing and retrieving contextual data collections for large language model (LLM) applications. The MCP is an open protocol that facilitates seamless integration between LLM applications and external data sources or tools, enabling LLMs to access the context they need efficiently. This server leverages Chroma's powerful data retrieval features, allowing AI models to create, manage, and query collections of generated data and user inputs. It supports various client types including ephemeral (in-memory) clients for testing, persistent file-based storage clients, HTTP clients for self-hosted Chroma instances, and cloud clients for integration with Chroma Cloud services. Key functionalities include comprehensive collection management such as creating, modifying, deleting collections, listing collections with pagination, and configuring vector search parameters like HNSW. Document operations are robust, supporting adding documents with metadata, semantic and full-text search queries, advanced filtering, and document retrieval by IDs or filters. The server also supports updating and deleting documents within collections. Chroma MCP supports multiple embedding functions including default, cohere, openai, jina, voyageai, and roboflow, with persistent embedding function configuration per collection to ensure consistent retrieval and insertion operations. It also provides detailed environment variable configurations for API keys and client settings, enhancing security and flexibility. The server is designed to integrate easily with applications like Claude Desktop, providing configuration examples for ephemeral, persistent, cloud, and self-hosted clients. It also offers demos and documentation to assist developers in leveraging its capabilities for building LLM applications with memory and contextual awareness. Overall, Chroma MCP Server is a comprehensive, flexible, and efficient solution for managing contextual data collections and enabling advanced search and retrieval functionalities in LLM-powered applications, adhering to the Model Context Protocol standards.
