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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "add",
    "arguments": {}
  }
}
```

## Why add is rated Low

The description is empty and the name 'add' is too ambiguous to classify confidently. In the context of an Ethereum toolkit, it could mean adding a wallet to track, adding a token to a list, or something else entirely. Without any description, cannot assign a meaningful category. Defaulting to Other with very low confidence.

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

## Use case

AI agents call add as a supporting operation in Ethereum Tools workflows.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "add": {
      "limits": [
        {
          "counter": "add_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`
