WHAT IT DOES

What x_action does on CoWork OS

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

RISK

Why x_action is rated Medium

The tool supports read and search (lower severity) but also posting to a connected X/Twitter account, which is a Write operation with public social-media impact. Misuse could result in unauthorized public posts, reputation damage, or spam. Per the severity hierarchy, Write dominates Read, and public posting on social media carries high blast radius.

From the tool's definition 'post' — the tool can post content to X/Twitter using a connected account

RECOMMENDED RULE

The rule that runs x_action safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For x_action, this is the rule to start with:

x_action Rate-limited

x_action 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.

The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every x_action call is checked against it from then on.
