WHAT IT DOES

What publish does on Cws

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

Parameter	Type	Required	Description
`itemId`	string	—	Extension item ID (defaults to CWS_ITEM_ID env var)
`skipReview`	boolean	—	Attempt to skip review if the extension qualifies. Defaults to false.
`publishType`	string	—	DEFAULT_PUBLISH: publishes immediately after approval. STAGED_PUBLISH: stages for manual publishing after approval. Defaults to DEFAULT_PUBLISH.
`publisherId`	string	—	Publisher ID (defaults to CWS_PUBLISHER_ID env var or 'me')
`blockOnWarnings`	boolean	—	If true, the publish is blocked when the submission has warnings. Defaults to false.
`deployPercentage`	integer	—	Initial deploy percentage for staged rollout (0-100).

Parameters from the server's own tool schema.

RISK

Why publish is rated Medium

An AI agent can call publish faster than any human can review: one bad instruction and it creates or modifies resources in Cws by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs publish safely

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

publish Rate-limited

publish 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.

What parameters does publish accept? +

How do I enforce a policy on publish? +

What risk level is publish? +

publish is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit publish? +

How do I block publish completely? +

Set action: deny in the PolicyLayer policy for publish. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides publish? +
