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

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

```

## Why pypi_package is rated Low

This tool only queries and retrieves publicly available package metadata from PyPI. It performs no side effects, does not execute code, does not modify data, and does not access sensitive systems. The 'Keyless' note indicates public data access. This is a straightforward Read category tool with low severity due to the benign nature of the information accessed.

From the tool's own definition: "Tool description states 'Look up a Python (PyPI) package' with operations limited to retrieving 'latest version, summary, license, author, homepage, and required Python version.' These are all read-only metadata queries with no modification or execution…"

## Use case

AI agents call pypi_package to retrieve information from Livedatalink 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 Livedatalink:

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