How do I install the chroma mcp server?

This profile does not contain a verified copy-paste launch configuration. Follow the current project documentation to confirm the runtime, entry point, transport and authentication before registering it in your client.

What credentials does it need?

It reads `CHROMA_CLIENT_TYPE`, `CHROMA_DATA_DIR`, `CHROMA_TENANT`, `CHROMA_DATABASE`, `CHROMA_API_KEY`, `CHROMA_HOST`, `CHROMA_PORT`, `CHROMA_CUSTOM_AUTH_CREDENTIALS` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
