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

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

  "params": {
    "name": "list_channels",
    "arguments": {}

## Why list_channels is rated Low

This tool retrieves and queries channel data with no side effects. It only returns existing information sorted and filtered by parameters, with no capability to create, modify, delete, or execute operations. Standard read operation with minimal security risk—information exposure depends on channel visibility permissions already enforced by the application.

From the tool's own definition: "Tool description explicitly states 'List all Huly channels' with filtering and searching capabilities. The verb 'list' and absence of any modification, deletion, or execution language indicate a pure read operation."

## Use case

AI agents call list_channels to retrieve information from Huly 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 Huly:

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