THE RISK

Why get-nfrs needs a policy

This tool retrieves and queries Non-Functional Requirement documents without side effects. It performs a read-only operation consistent with other sibling tools (get-brds, get-prds, get-uirs, etc.) on the server. No data is created, modified, deleted, or executed.

From the tool's definition Tool name 'get-nfrs' and description 'Get Non-Functional Requirement Documents' indicate data retrieval. Returns 'ID, Title, Description' with no modification, deletion, or execution capability.

POLICY

How to control get-nfrs

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

policy.json

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

get-nfrs 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 Specifai 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.
