ChromaDB MCP Server: Open Source Vector Search

ChromaDB runs embedded or as a lightweight local server, making it the fastest path to a working vector-search MCP tool without provisioning a managed database.

Core Tools

• query_collection(collection_name, query_text, n_results)
• add_documents(collection_name, documents, metadatas)

When to Graduate Off ChromaDB

Embedded ChromaDB is great for prototypes and single-instance servers. Once you need horizontal scaling or multi-tenant isolation, most teams migrate to a managed vector database and keep the same MCP tool interface.
