create_sync · Polytomic MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_sync does on Polytomic MCP Server

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

WHY IT NEEDS A POLICY

Why create_sync needs a policy

This tool creates a new sync configuration/pipeline, which is a reversible Write operation. While the description is empty, the name and context clearly indicate configuration creation rather than deletion or execution of arbitrary commands. Severity is medium because misconfiguration could cause unwanted data synchronization but the operation itself is reversible via delete_sync.

From the tool's definition Tool name 'create_sync' combined with server description indicating it 'manage[s]...synchronization tasks' and 'trigger syncs' suggests the tool creates or initiates a synchronization configuration.

Verdict

create_sync Rate-limited

create_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.
