Can I use Chroma as a CLI?

Yes. KosmoKrator exposes a Chroma CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Chroma through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Chroma tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Chroma credentials stored?

Chroma credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Chroma MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Chroma CLI for CI

Use the Chroma CLI for CI with headless JSON commands, schema discovery, credentials, and permission controls.

Chroma CLI for CI

Run integration calls from CI jobs with JSON output, explicit credentials, and predictable exit status.

Use this shape when a pipeline needs to read or update an external service. The Chroma CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Chroma CLI for CI
kosmokrator integrations:configure chroma --set api_key="$CHROMA_API_KEY" --enable --read allow --write ask --json
kosmo integrations:call chroma.chroma_list_collections '{"limit":1,"after":"example_after"}' --json

Discovery Before Execution

Agents and scripts can inspect Chroma docs and schemas before choosing a function.

kosmo integrations:docs chroma --json
kosmo integrations:docs chroma.chroma_list_collections --json
kosmo integrations:schema chroma.chroma_list_collections --json
kosmo integrations:search "Chroma" --json
kosmo integrations:list --json

Useful Chroma CLI Functions

Function	Type	Parameters	Description
`chroma.chroma_list_collections`	Read	limit, after	List all vector collections in Chroma. Returns collection names and IDs that can be used for further operations.
`chroma.chroma_get_collection`	Read	collection_id	Get details of a specific Chroma collection by its name or UUID, including metadata and document count.
`chroma.chroma_create_collection`	Write	name, description, metadata	Create a new vector collection in Chroma. Collections are used to store and query document embeddings.
`chroma.chroma_add_documents`	Write	collection_id, ids, embeddings, documents, metadatas	Add documents with embeddings to a Chroma collection. Each document requires an ID and either embeddings or text content.
`chroma.chroma_query_documents`	Read	collection_id, query_embeddings, query_texts, n_results, where, where_document, include	Search for similar documents in a Chroma collection using query embeddings or text. Returns the most similar documents ranked by distance.
`chroma.chroma_get_document`	Read	collection_id, ids, where, where_document, include, limit, offset	Retrieve specific documents from a Chroma collection by their IDs. Returns the full documents including text, embeddings, and metadata.
`chroma.chroma_get_health`	Read	none	Check the health status of the Chroma vector database server. Returns heartbeat and version information.

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
