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

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

  "params": {
    "name": "skill_crud",

## Why skill_crud is rated High

CRUD operations on 'skills' in this context likely involve creating, reading, updating, and deleting skill definitions/scripts. The most severe applicable category across CRUD is Destructive (delete operations). However, since the description is empty and the tool name only says 'crud', there is uncertainty.

From the tool's own definition: "Tool name 'skill_crud' on a server described as enabling Claude to 'create, edit, run, and manage reusable skills' with 'executing scripts with automatic dependency management'. Sibling tools include 'execute_python_code' and 'run_skill_script'."

## Use case

AI agents invoke skill_crud to trigger actions in Skill Management MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "skill_crud": {
      "limits": [
        {
          "counter": "skill_crud_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
