How to Use the Cal.com MCP in AutoGen

Q: How do AutoGen agents use the Cal.com MCP Server?

You register the server tools using mcpservertools and pass them to your AssistantAgent. The agents then call tools like createbooking during their group conversations.

Q: Can AutoGen agents debate before canceling a Cal.com booking?

Yes, one agent can propose using cancelbooking while another checks the UID details. They only execute the cancelation once both agents agree on the action.

Build AutoGen agent teams that collaborate to verify availability, schedule, and manage Cal.com bookings.

Coordinate Multi-Agent Cal.com Scheduling in AutoGen

The `create_booking` tool allows your AutoGen coordination agent to generate Cal.com meeting URLs once the team agrees on a time. An AutoGen scheduling agent proposes a slot, a validation agent checks it, and the execution agent books it on Cal.com. This consensus-driven process ensures no Cal.com meeting is created without team agreement. You can set up an AutoGen conversation where agents debate whether a Cal.com booking fits your preferences. These Cal.com tools execute only after the AutoGen validation agent confirms that the attendee meets your criteria.

Automated Booking Verification and Conflict Resolution

The `get_booking` tool retrieves detailed Cal.com meeting data so your AutoGen validation agent can verify attendee credentials. If a conflict arises, the AutoGen performance agent flags the Cal.com issue in the group chat. The agents then negotiate a new Cal.com time based on the active rules. This setup eliminates Cal.com booking errors by forcing AutoGen agents to double-check the UID details. They discuss alternative Cal.com slots in the chat before executing any changes.

Multi-Agent Rescheduling with the MCP Server

The `reschedule_booking` tool modifies Cal.com host structures and updates guest links only after the AutoGen team approves the change. An AutoGen customer service agent requests the move, while a calendar agent finds the next open Cal.com slot. They collaborate to ensure the new Cal.com time works for both parties. Once they reach a consensus, the AutoGen adapter executes the tool and updates the Cal.com guest. This conversational approach keeps your Cal.com scheduling accurate and prevents accidental changes.

Setup guide

Set up Cal.com 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 Cal.com 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="Cal.com_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Cal.com 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="Cal.com_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

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

Yes, one agent can propose using `cancel_booking` while another checks the UID details. They only execute the cancelation once both agents agree on the action.
