Why roam_create_outline needs a policy

Based on the naming convention and context of sibling creation tools on this Roam Research server, 'roam_create_outline' almost certainly creates or structures new content in the graph. This is a reversible modification (outlines can be deleted or reorganized), making it Write rather than Destructive. The empty description prevents higher confidence, but the pattern is clear from related tools.

From the tool's definition Tool name is 'roam_create_outline' which indicates creation of a new outline structure in Roam Research. The sibling tools include 'roam_create_page' and 'roam_create_block' which are clearly Write operations, suggesting this follows the same pattern.

POLICY

How to control roam_create_outline

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

policy.json

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

roam_create_outline 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.
