Why spec_coding_requirements_start needs a policy

This tool initiates the requirements gathering phase and provides guidance — it reads/retrieves workflow state and returns instructional content. There are no side effects beyond potentially initializing a phase state in the workflow, which is at most a minor write. The dominant action is providing guidance (informational/read-like), and misuse has minimal blast radius.

POLICY

How to control spec_coding_requirements_start

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "spec_coding_requirements_start": {}
  }
}

spec_coding_requirements_start 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 Spec-driven Development 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.
