# list_agents

List all configured voice agents in your Retell account. WHEN TO USE: - Discover available agents before making calls - Find agent IDs by name - Inventory check COMMON MISTAKES: - Guessing agent IDs from names; use the returned agent_id exactly - Choosing an agent without checking its response_engine.llm_id and versions via get_agent ERROR RECOVERY: - 401: API key is missing or invalid → configure_retell_api_key RELATED TOOLS: - get_agent: Inspect full config for a returned agent_id - get_agent_versions: Check published versions - create_phone_call/create_web_call: Use a verified agent_id RETURNS: agents, count. Each agent usually includes agent_id, agent_name, voice_id, response_engine, and timestamps.

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

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

  "method": "tools/call",
  "params": {
    "name": "list_agents",
    "arguments": {}

## Why list_agents is rated Low

This tool retrieves and queries configuration data about voice agents without side effects. It is a simple inventory/discovery operation that returns information to inform subsequent actions. The related tools (get_agent, create_phone_call) are separate and handle more sensitive operations.

From the tool's own definition: "Tool description states 'List all configured voice agents in your Retell account' and use cases include 'Discover available agents', 'Find agent IDs by name', and 'Inventory check'. No data modification, deletion, or execution of external operations occurs."

## Use case

AI agents call list_agents to retrieve information from Freshdesk 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 Freshdesk:

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