Multi-agent coordination via CrewAI

`list_events` acts as the primary search tool for your research agent to analyze current schedule density. By scanning specific date ranges, the agent identifies free blocks before passing them to the scheduling agent. The MCP integration shares the tool output across the entire team memory. The scheduling agent then uses that context to run the next task without repeating the API call.

Autonomous proposal management

`list_proposals` gives your monitoring agent a clear view of pending meeting invites and proposed times. This tool returns the current status of each proposal, allowing the agent to flag outstanding items. The crew uses this data to trigger escalation tasks, like assigning a writer agent to draft a reminder email. This keeps your business pipeline moving without requiring you to manually check your inbox.

Specialized reminder routing

`create_reminder` allows your coordinator agent to delegate tasks directly to Apple Reminders or Todoist. The tool parses the agent's action items and creates structured tasks with clear deadlines. The MCP Server handles the formatting so the agent doesn't have to worry about provider-specific APIs. This setup ensures that your crew's internal task list matches your actual real-world workload.

Setup guide

Set up Fantastical MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Fantastical tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Fantastical Analyst",
    goal="Access and analyze Fantastical data via MCP.",
    backstory="Expert analyst with direct Fantastical access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Fantastical transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

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

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Fantastical Analyst",
        goal="Access and analyze Fantastical data via MCP.",
        backstory="Expert analyst with direct Fantastical access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Fantastical transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
