Frequently Asked Questions
Common questions about Chroma.
- What is the Chroma MCP and how can it be used?
- The Chroma MCP integrates with Chroma vector databases. It enables querying of Chroma collections to support retrieval-augmented generation (RAG) and other vector search applications.
- How can I install the Chroma MCP in a client like Cline?
- The Chroma MCP typically connects via stdio. Refer to your MCP client's documentation for instructions on configuring stdio-based MCPs. You will likely need to specify the path to an executable.
- Does the Chroma MCP require an API key or other authentication?
- No, the Chroma MCP is configured for 'none' authentication. It does not require API keys, OAuth, or other credentials for connection.
- What are the core capabilities exposed by the Chroma MCP?
- The Chroma MCP is designed for querying Chroma vector database collections. Its primary capabilities involve interacting with the vector database for search and retrieval operations.
- Is there a cost associated with using the Chroma MCP?
- The Chroma MCP itself is open source under an MIT license, as indicated by its repository. The cost depends on how and where you deploy and host your Chroma vector database instances.
- What is a prerequisite for using the Chroma MCP effectively?
- A key prerequisite for using the Chroma MCP is having a functional Chroma vector database instance with populated collections. Without a Chroma database, the MCP has no data to query.
