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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "lookup_packagist",
    "arguments": {
      "pkg": "<pkg>"
    }
  }
}
```

## Why lookup_packagist is rated Low

This is a pure read operation that queries a public package registry (Packagist/Composer) for metadata about PHP packages. It has no side effects, does not execute code, and does not alter any state. While the server charges per call (a financial model), the tool itself performs only a data retrieval operation.

From the tool's own definition: "Tool description explicitly states 'Get Packagist (PHP) package metadata' and the example call queries package information. The use case is 'PHP-dependency audits,' which are information-gathering activities."

## Use case

AI agents call lookup_packagist to retrieve information from GoCreative Agent API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoCreative Agent API:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "lookup_packagist": {}
  }
}
```
