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

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

## Why comprehension is rated Low

The description 'number' gives no meaningful indication of the tool's behavior. Given the Baidu Map context and sibling tools (adcode, address, city, etc.), this might relate to some numeric retrieval, but there is insufficient evidence to classify it as anything other than Other. Confidence is very low due to the uninformative description.

From the tool's own definition: "Tool name is 'comprehension' and description is merely 'number' — both are uninformative and provide no actionable detail about what the tool does."

## Use case

AI agents call comprehension as a supporting operation in Baidu Map workflows.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "comprehension": {
      "limits": [
        {
          "counter": "comprehension_rate",
          "window": "minute",
          "max": 60,
          "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`
