Why get-api-spec needs a policy

This tool retrieves existing API documentation (Swagger/OpenAPI specification) and converts it to markdown format for display. It has no side effects, does not execute code, does not modify data, and does not delete resources. It is a straightforward Read operation with minimal security risk.

From the tool's definition Tool description states 'Get and convert Swagger specification' — a retrieval and formatting operation with no modification or execution of data or systems.

POLICY

How to control get-api-spec

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 get-api-spec:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-api-spec": {}
  }
}

get-api-spec is read-only, so it stays allowed — but 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.
