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

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

  "method": "tools/call",
  "params": {
    "name": "package-show-dependencies",
    "arguments": {}

## Why package-show-dependencies is rated Low

This tool retrieves and displays information about Swift package dependencies—a read-only operation with no side effects. It falls squarely into the Read category (queries data, no side effects). The severity is low because misuse would at worst expose package structure information, posing minimal risk to systems or data integrity.

From the tool's own definition: "Tool name 'package-show-dependencies' and description 'Shows the dependency tree of a Swift package and returns structured dependency data' indicate a query/retrieval operation that reads and displays package metadata without modifying, executing, or deleting…"

## Use case

AI agents call package-show-dependencies to retrieve information from Http 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 Http:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "package-show-dependencies": {}
  }
}
```
