## Facts

- Server: C4REQBER (`C4MIND/C4REQBER`) — https://policylayer.com/tools/c4reqber.md
- Homepage: https://github.com/C4MIND/C4REQBER
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "c4_codegen",
    "arguments": {}
  }
}
```

## Why c4_codegen is rated High

The name 'c4_codegen' strongly implies code generation functionality, which typically falls under Execute as it produces and potentially runs code. However, with an empty description, confidence is reduced. The server context mentions 'formal verification' and '21 MCP tools' for a cognitive exoskeleton system, suggesting this tool generates code artifacts.

From the tool's own definition: "Tool name 'c4_codegen' suggests code generation; description is empty and uninformative."

## Use case

AI agents invoke c4_codegen to trigger actions in C4REQBER. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## 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_codegen": {
      "limits": [
        {
          "counter": "c4_codegen_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
