rag_index · Ragi MCP: Risk & Policy

WHAT IT DOES

What rag_index does on Ragi

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

WHY IT NEEDS A POLICY

Why rag_index needs a policy

Indexing is a Write operation: it processes source files and creates or updates stored embeddings/index structures. It does not delete existing data (so not Destructive), does not execute code, and has no financial impact. Misuse could cause unwanted indexing of sensitive files or corruption of an existing index, warranting medium severity.

From the tool's definition 'Index files/directories for the specified project' — this tool reads files from disk and writes/creates index entries (embeddings, metadata) in a local RAG store.

Verdict

rag_index Rate-limited

rag_index 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.
