THE RISK

Medium Risk

Why add-work-item-comment needs a policy

This tool creates/appends new data (a comment) to an existing work item, which is a reversible modification. It does not execute arbitrary code, delete data, move money, or cause destructive effects. The severity is medium because comments can influence team decisions and workflows within a DevOps pipeline, but the effect is limited to annotation and can be edited or deleted by authorized users.

From the tool's definition Tool is named 'add-work-item-comment' and described as 'Add a comment to an existing work item in Azure DevOps'. The verb 'Add' and the action of appending a comment indicates creation of new content that modifies the work item state.

POLICY

How to control add-work-item-comment

PolicyLayer is an MCP gateway — it sits between your AI agents and DevOps Enhanced MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for add-work-item-comment:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "add-work-item-comment": {
      "limits": [
        {
          "counter": "add-work-item-comment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

add-work-item-comment 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.
