Why todoist_update_comment needs a policy

This tool creates or modifies data reversibly, fitting the Write category. It updates a comment (non-destructive change), affecting only a single comment's content. Severity is low because the blast radius is minimal—a malicious agent could deface a comment, but the change is easily undone by a user. Confidence is high because the description and name clearly indicate an update/modification operation.

From the tool's definition Tool name 'todoist_update_comment' and description 'Update an existing comment by its ID' indicate modification of existing data. The action is reversible—comments can be edited again or reverted.

How to control todoist_update_comment

PolicyLayer is an MCP gateway — it sits between your AI agents and Enhanced Todoist MCP Server Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for todoist_update_comment:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "todoist_update_comment": {
      "limits": [
        {
          "counter": "todoist_update_comment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
