update_file_metadata · Coord MCP: Risk & Policy

WHAT IT DOES

What update_file_metadata does on CoordMCP

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

WHY IT NEEDS A POLICY

Why update_file_metadata needs a policy

Updating metadata is a Write operation—it modifies data reversibly. Severity is medium because metadata corruption could disrupt task tracking and file locking coordination across agents, but the impact is less severe than data deletion or code execution. Confidence is 0.75 due to the empty description; a non-empty description specifying what metadata can be modified would increase confidence.

From the tool's definition Tool name 'update_file_metadata' indicates modification of file metadata. Description is empty, limiting confidence.
