ChromaDB Remote MCP Server

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. Its 25 documented tools cover chroma, collection, documents, count.

People who need cloud infrastructure tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install ChromaDB Remote MCP Server

before you install - you'll need

Set MCP_AUTH_TOKEN, ALLOWED_ORIGINS, DOCKER_REPO, DOCKER_USERNAME, DOCKER_PASSWORD before connecting.

Claude Code

claude mcp add meloncafe-chromadb-remote-mcp --transport http https://meloncafe.github.io/chromadb-remote-mcp/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "meloncafe-chromadb-remote-mcp": {
      "url": "https://meloncafe.github.io/chromadb-remote-mcp/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as container (OCI image) - can be sandboxed away from your filesystem · remote - your agent's requests go to meloncafe.github.io

license MIT - declared in the repository

registry namespace io.github.meloncafe is GitHub-verified and matches the repo owner

03 · What ChromaDB Remote MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can list all collections (with limit / offset), create a new collection (configuration / schema optional), rename / change metadata or configuration (v2.2.0), and delete a collection.

The 25 tools it gives your agent

Extracted from the project's README - what ChromaDB Remote MCP Server lets an agent do.

chroma_list_collections: - List all collections (with limit / offset)
chroma_create_collection: - Create a new collection (configuration / schema optional)
chroma_get_or_create_collection: - Idempotent create-or-get (v2.2.0)
chroma_modify_collection: - Rename / change metadata or configuration (v2.2.0)
chroma_delete_collection: - Delete a collection
chroma_get_collection_info: - Get collection metadata
chroma_get_collection_count: - Get document count (read_level optional)
chroma_count_collections: - Total collection count (v2.2.0)
chroma_peek_collection: - Preview collection contents
chroma_add_documents: - Add documents (with uris for multi-modal)
chroma_upsert_documents: - Idempotent insert-or-update (v2.2.0)
chroma_query_documents: - Semantic search (with query_uris / ids pre-filter)

show all 25 tools

chroma_get_documents: - Retrieve documents (read_level optional)
chroma_update_documents: - Update existing documents (with embeddings / uris)
chroma_delete_documents: - Delete by ids and/or where / where_document filter
chroma_heartbeat: - Server heartbeat (nanosecond timestamp)
chroma_get_server_version: - Server version string
chroma_get_max_batch_size: - Max batch size (for client-side splitting)
chroma_get_user_identity: - Current tenant + databases
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 loc
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).
chroma_reset_database: - Reset entire database (irreversible)
chroma_admin_delete_database: - Delete a database (requires both flags)
