Chroma's own MCP server covers the full collection lifecycle: create, list, inspect, peek, modify and delete, plus adding, updating, querying and removing documents. The same server works against an in-memory instance, a local persistent directory, a self-hosted HTTP deployment or Chroma Cloud, selected with a client-type flag. That range makes it convenient for prototyping a retrieval setup locally and pointing the identical configuration at a hosted database later. Credentials are only needed for the cloud and HTTP modes.
