team_sync · Musubix MCP: Risk & Policy

WHAT IT DOES

What team_sync does on Musubix

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

WHY IT NEEDS A POLICY

Why team_sync needs a policy

The tool synchronizes team patterns and knowledge with a remote system, implying both reading local data and writing/uploading to a remote endpoint. Synchronization is typically reversible (Write category). Severity is medium because it could overwrite remote or local data, but it is not clearly destructive or irreversible.

From the tool's definition 「チームのパターンとナレッジをリモートと同期します」(Synchronizes team patterns and knowledge with remote)

team_sync Rate-limited

team_sync 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.
