Coordinate multi-agent newsletter drafts in CrewAI

Using `create_email` allows your writer agent to draft content while an editor agent reviews it using `get_email`. This division of labor keeps your production line moving. Each agent executes its specific task sequentially, passing the results along without manual intervention.

Automate list moderation with this MCP Server

Calling `list_subscribers` lets your moderator agent identify inactive addresses and apply `delete_subscriber` to clean your list. By delegating this task to an autonomous crew, you avoid manual list cleaning. The agents run scheduled audits in the background while you focus on content.

Synchronize tags and webhooks across campaigns

Fetching current categories via `list_tags` allows a coordinator agent to configure event listeners using `create_webhook`. When new tags are created, the agent updates subscriber profiles using `update_subscriber`. This ensures your external integrations stay aligned with your audience segments.

Setup guide

Set up Buttondown Alternative 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 Buttondown Alternative tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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