WHAT IT DOES

What upload_document does on Daniel LightRAG MCP Server

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

RISK

Why upload_document is rated Medium

The upload_document tool creates or adds new document data to the LightRAG knowledge graph system. This is a reversible modification (documents can be deleted via sibling tool delete_document), making it a Write operation rather than Destructive.

From the tool's definition Tool name 'upload_document' combined with description 'Upload a document file to LightRAG' indicates document creation/addition to the system. This is a write operation that creates new data in the LightRAG system.

The rule that runs upload_document safely

upload_document Rate-limited

upload_document 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.
