How to Use the Calendarific MCP in CrewAI

Q: How do I configure the Calendarific MCP Server in CrewAI?

Install crewaitools and pass the secure Vinkius URL directly inside the agent's mcps parameter. This instantly exposes all holiday tools to that specific agent within your crew.

Q: How do I limit which Calendarific tools a CrewAI agent can use?

Use the MCPServerHTTP class from crewai.mcp and apply a toolfilter. This lets you restrict access to sensitive tools like getaccountinfo while exposing public holiday lookups.

Perplexity

Equip CrewAI specialized agents with global holiday context

Your CrewAI research agent queries `list_supported_countries` to identify target markets, while a scheduling agent uses `list_holidays` to map out campaign dates. CrewAI coordinates these specialized agents, allowing them to share holiday data through a unified memory system. To set this up, pass your Vinkius HTTP endpoint for Calendarific directly into the CrewAI agent configuration using the `mcps` list. The crew automatically shares access to all holiday tools without requiring manual wiring for each agent.

Filter holiday data across sequential crew tasks

A CrewAI moderator agent filters incoming holiday data using `list_holidays_by_type` before passing the list to an execution agent. This sequential pipeline ensures your autonomous crew only processes relevant national or religious events. You don't have to manually pass keys; use the CrewAI MCP library to restrict agent access to sensitive tools like `get_account_info`. This keeps junior agents focused entirely on public holiday lookups.

Coordinate localized operations using regional MCP Server tools

Your autonomous CrewAI crew manages localized operational schedules by calling `list_holidays_by_location` across different team agents. One agent monitors US state holidays while another tracks German regional holidays, coordinating handoffs in real-time. The CrewAI agents use shared memory to translate language codes via `list_supported_languages` and localize holiday names automatically. Because CrewAI supports standard HTTP and SSE transports, your agents run queries against the Calendarific endpoint without latency.

Setup guide

Set up Calendarific 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 Calendarific tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Calendarific 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.

crew.py

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="Calendarific Analyst",
        goal="Access and analyze Calendarific data via MCP.",
        backstory="Expert analyst with direct Calendarific access.",
        tools=mcp_tools,
    )

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

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