How to Use the MailerLite MCP in CrewAI

Q: How do I connect the MailerLite MCP Server to a CrewAI agent?

Install the library using pip install crewai 'crewaitools'. You can then pass your Vinkius HTTP endpoint URL directly into the agent's constructor using the mcps list parameter.

Collaborative Segment Analysis with CrewAI

The `list_segments` tool allows your CrewAI analyst agent to inspect subscriber engagement patterns across your email lists. The analyst agent retrieves this data directly through the MailerLite MCP Server to share with the rest of the crew. Because CrewAI uses role-based specialization, one agent can pull the segment data while another uses that information to generate tailored newsletter topics, all operating without human intervention.

Autonomous List Organization via MCP Server

The `create_group` tool enables your CrewAI operations agent to automatically organize subscribers based on their interaction history. The agent monitors incoming leads and sorts them into specific buckets. You can set up a hierarchical crew where a supervisor agent reviews the newly created subscriber groups before authorizing the operations agent to execute the final sorting.

Automated Campaign Reporting Teams

The `list_campaigns` tool retrieves historical performance metrics so your CrewAI reporting agent can draft weekly engagement summaries. The agent compiles open rates, click rates, and unsubscribe statistics automatically. The reporting agent then hands this summary to a writer agent, who drafts the next campaign draft based on what worked best in previous sends, creating a closed loop of autonomous email marketing.

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()
    print(result)

Common questions about MailerLite MCP in CrewAI

Install the library using pip install crewai 'crewai[tools]'. You can then pass your Vinkius HTTP endpoint URL directly into the agent's constructor using the mcps list parameter.

Yes, you can use the MCPServerHTTP client from CrewAI along with a tool filter to selectively expose tools. This prevents a research agent from executing destructive actions on your MailerLite MCP Server.

CrewAI agents use a shared memory system. When your research agent calls get_subscriber, the retrieved profile details are immediately accessible to other agents in the crew for analysis or segmentation.

Yes, you can define a sequential process where Agent A calls list_campaigns to find underperforming emails, and Agent B uses create_group to isolate unengaged subscribers using our secure MCP tools.

Your campaign metadata, subscriber lists, and email logs are never cached or logged by Vinkius. All tool outputs pass directly to your local Python runtime over secure, encrypted channels.
