THE RISK

Low Risk

Why cort.think.simple needs a policy

Based on the server description, CoRT tools implement a chain-of-recursive-thoughts methodology for AI reasoning. Sibling tools suggest this is a simplified thinking/reasoning tool with no data modification, execution, or financial implications. With no description, confidence is low, but the pattern strongly suggests a read-only or stateless reasoning operation.

From the tool's definition Tool description is empty and uninformative; tool name 'cort.think.simple' suggests a thinking/reasoning operation with no external side effects.

POLICY

How to control cort.think.simple

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "cort.think.simple": {
      "limits": [
        {
          "counter": "cort.think.simple_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

cort.think.simple gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register CoRT 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.
