Why metacognitive_reflection needs a policy

Based on the server context (advanced sequential thinking, structured reasoning), this tool likely performs internal reflection/analysis on thinking processes — a read-like cognitive operation with no external side effects. However, the empty description significantly lowers confidence.

From the tool's definition Tool name is 'metacognitive_reflection'; description is empty or uninformative.

POLICY

How to control metacognitive_reflection

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "metacognitive_reflection": {
      "limits": [
        {
          "counter": "metacognitive_reflection_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

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