Why create-api-group needs a policy

This tool creates a new organizational resource (API group) in Xano, which is a reversible operation—the group can be deleted or modified afterward. This qualifies as Write rather than Execute or Destructive. While creating API groups could indirectly affect API behavior, the primary function is data/resource creation, not code execution or irreversible deletion.

From the tool's definition Tool name 'create-api-group' and description 'Create a new API group in the Xano workspace' indicate data creation/modification.

POLICY

How to control create-api-group

PolicyLayer is an MCP gateway — it sits between your AI agents and Xano MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create-api-group:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create-api-group": {
      "limits": [
        {
          "counter": "create-api-group_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create-api-group 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.

Create a free account and register Xano MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
