WHAT IT DOES

What updateDocuments does on SourceSync Ai MCP Server

AI agents use updateDocuments 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 updateDocuments needs a policy

This tool creates or modifies data reversibly by updating document metadata. While it affects multiple documents via filter criteria (potentially high blast radius if filters are overly broad), the changes are not destructive or irreversible, placing it in the Write category. Severity is medium because misuse could affect many documents' metadata, but the changes can be reverted through subsequent updates.

From the tool's definition Tool description states "Updates metadata for documents that match the specified filter criteria." The verb "Updates" indicates modification of existing data. Metadata updates are reversible changes to document properties rather than deletion or destruction.
