Why create_fabric_link_control_policy needs a policy

This tool creates and configures a data center network policy (link control policy for fabric), which modifies infrastructure configuration state but is reversible through updates or deletions. It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition create_fabric_link_control_policy performs creation of a policy for managing data center fabric links, as indicated by 'create' in the name and 'Create a link control policy' in the description

How to control create_fabric_link_control_policy

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_fabric_link_control_policy": {
      "limits": [
        {
          "counter": "create_fabric_link_control_policy_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_fabric_link_control_policy stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Intersight 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.

How do I enforce a policy on create_fabric_link_control_policy? +

Register the Intersight MCP Server MCP server in PolicyLayer and add a rule for create_fabric_link_control_policy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Intersight MCP Server. Nothing to install.

What risk level is create_fabric_link_control_policy? +

create_fabric_link_control_policy is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_fabric_link_control_policy? +

How do I block create_fabric_link_control_policy completely? +

Set action: deny in the PolicyLayer policy for create_fabric_link_control_policy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_fabric_link_control_policy? +

create_fabric_link_control_policy is provided by the Intersight MCP Server MCP server (jim-coyne/intersight_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Intersight MCP Server tool call.

Start from Intersight MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
