WHAT IT DOES

What index_documents_batch does on MCP RAG Server

AI agents use index_documents_batch to create or update resources in MCP RAG Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP RAG Server environment.

RISK

Why index_documents_batch is rated Medium

This tool writes multiple documents into the knowledge base (ChromaDB vector storage) in batch. It creates new entries or overwrites existing ones, which is a reversible write operation. It does not delete data, execute code, or involve financial transactions. The batch nature increases the blast radius slightly compared to single-document indexing, but it remains a medium-severity write action.

From the tool's definition 'Index multiple documents at once' — creates/stores document embeddings in ChromaDB vector storage

RECOMMENDED RULE

The rule that runs index_documents_batch safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP RAG Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For index_documents_batch, this is the rule to start with:

index_documents_batch Rate-limited

index_documents_batch stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
