ingestFile · SourceSync Ai MCP Server MCP: Risk & Policy

WHAT IT DOES

What ingestFile does on SourceSync Ai MCP Server

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

WHY IT NEEDS A POLICY

Why ingestFile needs a policy

Ingesting a file creates new content/data within the namespace. This is a reversible write operation (documents can be deleted later), not destructive. The blast radius is medium as it could introduce unwanted or malicious content into the knowledge base.

From the tool's definition Ingests a file into the namespace. Supports various file formats with automatic parsing.
