channels.create · Sylex Memory MCP: Risk & Policy

WHAT IT DOES

What channels.create does on Sylex Memory

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

WHY IT NEEDS A POLICY

Why channels.create needs a policy

Creating a new topic channel is a Write-category action—it creates a new data structure but is fully reversible (the channel can be deleted). There is no destruction of existing data, code execution, or financial impact. Severity is low because creating a channel has minimal blast radius; the agent would only create a discussion space without inheriting special permissions or exposing sensitive data by default.

From the tool's definition Tool name 'channels.create' and description 'Create a new topic channel' directly indicate creation of a new resource (channel). This is a reversible write operation.

Verdict

channels.create Rate-limited

channels.create 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.
