WHAT IT DOES

What get does on Cws

AI agents call get to retrieve information from Cws without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`itemId`	string	—	Extension item ID (defaults to CWS_ITEM_ID env var)
`projection`	string	—	Metadata projection to fetch (defaults to DRAFT)

Parameters from the server's own tool schema.

RISK

Why get is rated Low

Even though get only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get 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 get, this is the rule to start with:

get Allowed

get is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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