@chroma-mcp Write Risk 3/5

// WHEN AI AGENTS USE THIS TOOL

AI agents use chroma_modify_collection to create or modify resources in ChromaDB. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON CHROMA_MODIFY_COLLECTION

Without a policy, an AI agent could call chroma_modify_collection repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach ChromaDB.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

  chroma_modify_collection:

What does the chroma_modify_collection tool do? +

Update a collection name or metadata. It is categorised as a Write tool in the ChromaDB MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on chroma_modify_collection? +

Add a rule in your Intercept YAML policy under the tools section for chroma_modify_collection. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the ChromaDB MCP server.

What risk level is chroma_modify_collection? +

chroma_modify_collection is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit chroma_modify_collection? +

Yes. Add a rate_limit block to the chroma_modify_collection rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block chroma_modify_collection completely? +

Set action: deny in the Intercept policy for chroma_modify_collection. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides chroma_modify_collection? +

chroma_modify_collection is provided by the ChromaDB MCP server (@chroma-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
