Chroma MCP Server

chroma_fork_collection

Duplicate an existing Chroma collection into a new collection with optional custom metadata, enabling data versioning or isolated experimentation.

Instructions

Fork a Chroma collection.

Args:
    collection_name: Name of the collection to fork
    new_collection_name: Name of the new collection to create
    metadata: Optional metadata dict to add to the new collection

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, and the description lacks behavioral details. It does not disclose whether the fork is deep or shallow, if metadata is copied, or if the operation is reversible. The brief description leaves significant ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short but structured as a docstring with repeated 'Args:' lines. It could be more concise, e.g., by combining the purpose and parameter descriptions. Every sentence is functional but not optimally efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and the complexity of a mutation tool, the description is insufficient. It fails to explain what happens to existing data, whether embeddings are copied, or how success is indicated. The tool's behavior remains opaque.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds minimal meaning beyond parameter names: 'Name of the collection to fork' and 'Name of the new collection to create' are largely redundant. It also mentions an optional 'metadata' parameter that is not present in the input schema, creating inconsistency. Schema coverage is 0%, so the description should compensate more.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'Fork a Chroma collection', which is a specific verb and resource indicating duplication. However, it does not differentiate from sibling tools like chroma_create_collection or chroma_delete_collection, as 'fork' could imply partial copying or aliasing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as the original collection must exist, or contrast with creating a new collection from scratch.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
