Coordinate Support Teams with AutoGen Agents

The JustCall MCP Server lets your conversational agents collaborate on customer routing. One agent can use `list_team_users` to see who is online, while another checks the caller's history with `get_contact` to decide who should handle the account. This debate happens entirely in the background. The agents negotiate the best assignment, then update the CRM record or notify the team without human intervention.

Run Multi-Agent SMS Campaigns via AutoGen

This MCP Server provides `send_message` and `list_messages` to let your agents manage text campaigns through structured discussion. A copywriter agent drafts a text, a compliance agent checks it against recent logs, and a sender agent dispatches it. They use `get_message_details` to track delivery status and replies. If a customer responds negatively, the agents huddle, analyze the tone, and decide whether to escalate to a live call.

Automate CRM Updates with Consensus

The `create_contact` tool allows your agents to safely modify your phone directory after agreeing on the data. Before making changes, they verify the details using `get_account_profile` to avoid creating duplicate profiles. By requiring consensus before running write operations, you prevent messy data overwrites. Your agents double-check their work by comparing live `list_calls` logs against your database.

Setup guide

Set up JustCall MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes JustCall tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="JustCall_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent JustCall data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="JustCall_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent JustCall data")
    print(result.messages[-1].content)

Common questions about JustCall MCP in AutoGen

Install `autogen-ext[mcp]` and use the streamable HTTP server parameters to fetch the tools. Pass the resulting list straight to your assistant agent constructor.

Yes. Your agents can invoke `send_message` to dispatch SMS or MMS. They can discuss the content of the message first to ensure it meets your brand standards.

You configure the conversation flow so agents must agree. For example, one agent might want to call a number via `list_account_numbers` while another blocks it based on call history.

No. The adapter handles all schema conversions behind the scenes. Your agents read and execute tools like `list_calls` using native JSON formats.

Your call details and contact info flow directly through secure, ephemeral V8 isolates. Vinkius never writes this sensitive communication data to disk, keeping your customer records private.
