## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "c4_bayesian",
    "arguments": {}
  }
}
```

## Why c4_bayesian is rated Low

The description is empty and uninformative. The name 'c4_bayesian' suggests some form of Bayesian analysis or probabilistic reasoning, which could be a read/compute operation, but without any description we cannot determine the actual behavior. Given the server context (cognitive exoskeleton, discovery pipeline, formal verification), it likely performs some kind of probabilistic inference or analysis.

From the tool's own definition: "Tool name is 'c4_bayesian' with an empty description. No information about what the tool does is available."

## Use case

AI agents call c4_bayesian as a supporting operation in C4REQBER workflows.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches C4REQBER:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "c4_bayesian": {
      "limits": [
        {
          "counter": "c4_bayesian_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}
