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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "gluecron_list_tree",
    "arguments": {
      "ref": "<ref>",
      "repo": "<repo>",
      "owner": "<owner>"

## Why gluecron_list_tree is rated Low

This tool only queries and returns data about repository structure. It has no side effects, cannot modify, delete, or execute code. The GET semantics and absence of write/delete capability place it firmly in the Read category with low severity.

From the tool's own definition: "Tool name 'list_tree' and description 'List directory contents at a ref' — retrieves file system structure without modification. The description explicitly states it 'Mirrors GET /api/v2/repos/.../tree/:ref', confirming a read-only HTTP GET operation."

Risk signals: Accepts file system path (path)

## Use case

AI agents call gluecron_list_tree to retrieve information from Gluecron 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 Gluecron:

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