POLICY

How to control analyze_link_graph

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Writer's Aid MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_link_graph:

policy.json

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

analyze_link_graph is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
