See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-21 Evidence 4 linked sources Publisher Chroma Licence Apache-2.0 ↗ Revision 98ff67589bdc Read what was—and wasn’t—checked ↓ “This is a MCP server for self-hosting your access to Chroma.” Chroma · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Documents collection and document operations rather than claiming retrieval alone. - Exposes persistent, ephemeral, HTTP and cloud Chroma connection choices in its configuration. ### A good fit for - Exploring a Chroma collection or building a small collection from task-specific material. ### Weigh up before choosing - The default client is ephemeral; persistence requires explicit configuration. - Creation, modification and deletion tools are present; database authentication and embedding-provider choices affect data exposure. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - README.md (installation, capability and permission sections) - pyproject.toml - src/chroma_mcp/server.py - LICENSE ### Our findings - The server entrypoint selects Chroma client and embedding configuration from CLI/environment settings. - Chroma client types describe database connections, not four different MCP transports. ### Not established by this review - Server startup, authentication and tool execution were not tested. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. Upstream setup instructions ↗ DOCUMENTED COMMAND uvx chroma-mcp Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - Select persistent, HTTP or cloud configuration if an ephemeral database is unsuitable. - Configure database and optional embedding-provider credentials outside the prompt. ### Before you start - uv/Python; database connection details and embedding-provider credentials when required. ### Compatibility An MCP client supporting stdio. · uv/Python; database connection details and embedding-provider credentials when required. ### Implementation Python ### Transports stdio ### Vector data management / Configured credentials or local access - Reads, adds, updates and deletes collection/document data. - Selected remote embedding functions may send text to another service. ### Cost model Local compute or Chroma Cloud usage and any external embedding service determine cost. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource.
