WHAT IT DOES

RECOMMENDED RULE

The rule that runs preview_app_blueprint safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sanka MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For preview_app_blueprint, this is the rule to start with:

preview_app_blueprint Allowed

preview_app_blueprint is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "preview_app_blueprint": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Sanka MCP Server, apply this rule, and every preview_app_blueprint call is checked against it from then on.
