Agents Tools

Create and run phone voice agents through the MCP server.

Setup note: Phone lines (60db Dialer numbers and SIP trunks) are added in the 60db dashboard or with the Agents API. The MCP server can list them, but cannot create or delete them. SIP usernames and passwords are never shown.

Available Tools

Tool	Purpose
`sixtydb_agents_list`	List agents
`sixtydb_agents_get`	Get one agent
`sixtydb_agents_create`	Create an agent
`sixtydb_agents_update`	Change an agent’s fields
`sixtydb_agents_delete`	Delete an agent (requires `confirm: true`)
`sixtydb_agents_place_call`	Place an outbound call (requires `confirm: true`; rings a real phone and costs money)
`sixtydb_agents_list_calls`	Call history, filterable by agent and status
`sixtydb_agents_get_call`	Status, duration, cost and summary of one call
`sixtydb_agents_get_transcript`	Turn-by-turn transcript of a call
`sixtydb_agents_list_phone_lines`	Phone lines agents can call from (no SIP secrets)

Note: confirm: true is required for sixtydb_agents_place_call and sixtydb_agents_delete. Without it, the tool does nothing and explains what would happen.

Create an Agent

{
  "tool": "sixtydb_agents_create",
  "arguments": {
    "name": "Front desk",
    "script": "You are the receptionist for Juniper Kitchen. Keep replies short.",
    "voice_id": "YOUR_VOICE_ID",
    "greeting": "Hello, Juniper Kitchen. How can I help?",
    "listen_languages": ["hi", "en"]
  }
}

The result includes webhook_secret, which is shown once. Store it before you continue. Tools and webhook URLs are set with tools, tool_webhook_url and event_webhook_url. See Tools and webhooks.

Update an Agent

Send the agent_id and only the fields to change:

{
  "tool": "sixtydb_agents_update",
  "arguments": {
    "agent_id": "9c2e1d7a-0b3f-4e6a-8f1d-5a7b9c0e2d44",
    "greeting": "Hi there! What can I do for you?"
  }
}

Place a Call (Requires Confirmation)

to is in E.164 format. phone_line_id comes from sixtydb_agents_list_phone_lines. Without confirm: true, nothing is called. The tool returns the cost and what will happen:

{
  "tool": "sixtydb_agents_place_call",
  "arguments": {
    "agent_id": "9c2e1d7a-0b3f-4e6a-8f1d-5a7b9c0e2d44",
    "to": "+919999999999",
    "phone_line_id": "2d8e4f10-6a3b-4c9d-8e7f-0b1a2c3d4e5f",
    "metadata": { "crm_lead_id": "L-1042" },
    "confirm": true
  }
}

The result is the queued call. Track it with sixtydb_agents_get_call, passing call_id.

List Calls and Read Results

{
  "tool": "sixtydb_agents_list_calls",
  "arguments": {
    "agent_id": "9c2e1d7a-0b3f-4e6a-8f1d-5a7b9c0e2d44",
    "status": "completed",
    "limit": 20
  }
}

{
  "tool": "sixtydb_agents_get_call",
  "arguments": { "call_id": "6b1f0c52-4d7e-4b8a-9d3e-2a1c8e7f0a11" }
}

{
  "tool": "sixtydb_agents_get_transcript",
  "arguments": { "call_id": "6b1f0c52-4d7e-4b8a-9d3e-2a1c8e7f0a11" }
}

Delete an Agent (Requires Confirmation)

{
  "tool": "sixtydb_agents_delete",
  "arguments": {
    "agent_id": "9c2e1d7a-0b3f-4e6a-8f1d-5a7b9c0e2d44",
    "confirm": true
  }
}

Deleting detaches the agent from its phone lines. The phone lines and past calls are kept.

Important Notes

Placing a call costs money. It uses AI credits for speech and LLM use, plus the Dialer balance for line minutes on a 60db number. A BYO line is billed by your carrier.
Only call people who agreed to be called. Follow your local recording rules when record is on.
Secrets stay hidden. SIP usernames, domains and passwords are never returned. The webhook secret appears only in the create and rotate responses.
Calls from MCP are tagged. They show source: "mcp" in call history.
Pricing and limits: see Agents.
