WHAT IT DOES

What scope_guardrails does on ContextForge MCP Gateway

AI agents call scope_guardrails to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why scope_guardrails is rated Low

This tool performs a read-only check or query operation. It inspects proposed features against guardrails (policy rules or constraints) and returns a validation result. There is no indication of data modification, deletion, code execution, or financial impact. The 'check' verb indicates inspection rather than action.

From the tool's definition Tool name 'scope_guardrails' with description 'Check proposed features against scope guardrails' describes a validation/checking operation that retrieves or evaluates information against predefined rules without modifying data or triggering external actions.

scope_guardrails Allowed

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

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