How to Use the MailerLite MCP in CrewAI

Q: How do I filter tools for a specific MailerLite agent in CrewAI?

Autonomous MailerLite crews for CrewAI

Assign a dedicated agent to monitor your campaigns using `list_campaigns`. If a campaign underperforms, the agent can alert the rest of your crew. This allows your team to focus on strategy while the agents handle the reporting. It turns passive data into active insights.

Segmented lead routing in CrewAI

Use a specialized agent to analyze leads and route them using `add_subscriber_to_group`. The agent reads incoming data and assigns users to the right buckets. It removes the need for manual sorting. You define the rules, and the agents execute them across your entire subscriber base.

Subscriber data hygiene in CrewAI

Configure a monitor agent to audit your lists with `list_subscribers`. If it finds bounced or junk records, it can call `delete_subscriber` to keep your list healthy. It keeps your deliverability high without human intervention. Your agents work continuously to ensure your marketing data stays accurate.

Setup guide

Set up MailerLite 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 MailerLite tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent MailerLite 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="MailerLite Analyst",
        goal="Access and analyze MailerLite data via MCP.",
        backstory="Expert analyst with direct MailerLite access.",
        tools=mcp_tools,
    )

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

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