Remote ChromaDB vector database MCP server with streamable HTTP transport
Remote ChromaDB vector database MCP server with streamable HTTP transport
A Streamable HTTP MCP (Model Context Protocol) server that provides remote access to ChromaDB for AI assistants like Claude. Enables semantic search and vector database operations from mobile devices and remote locations.
All clients access the same self-hosted ChromaDB through this remote MCP server. Vector embeddings and semantic search results persist across all platforms.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| chroma_search | Hybrid dense + sparse search (RRF). The algorithm itself works on a single node; chromadb open-source simply hasn't implemented the search() endpoint in the local executor. |
| chroma_fork_collection | Zero-copy fork (segment-level operation on object storage — architecturally requires the distributed compactor/storage stack). |
| chroma_get_fork_count | Fork metadata lookup (depends on the distributed metadata store). |
| chroma_get_indexing_status | WAL offset + compactor index progress (requires the distributed WAL/compactor services). |
| Variable | Description | Required |
|---|---|---|
| MCP_AUTH_TOKEN | Credential the server authenticates with. | Yes |
| CHROMA_DATA_PATH | Filesystem location the server is allowed to use. | Optional |
| CHROMA_HOST | Endpoint or connection string the server talks to. | Optional |
| CHROMA_AUTH_TOKEN | Credential the server authenticates with. | Yes |
