Q: Can a CrewAI agent update subscriber details in MailWizz?

Yes, a CrewAI agent with access to the server can call updatelistsubscriber to modify MailWizz contact info or custom fields based on team instructions.

Q: Can I restrict which MailWizz tools my CrewAI agents can access using the MCP protocol?

Yes, you can use the toolfilter option in CrewAI's MCPServerHTTP class to expose only specific MailWizz tools, like listemailcampaigns, while hiding administrative tools.

Run CrewAI agent squads for MailWizz campaigns

Assign specialized roles to your CrewAI agents to coordinate MailWizz campaigns via `list_email_campaigns`. They work together in sequence within your CrewAI setup to manage MailWizz. The CrewAI Operator agent can decide to call `pause_email_campaign` if the Researcher agent flags a sudden drop in MailWizz open rates, running the entire campaign loop autonomously.

Keep lists updated using an autonomous MCP Server setup

Let your CrewAI agents manage MailWizz database cleanup on their own using `list_subscriber_collections`. It then uses `add_subscriber_to_list` or `delete_list_subscriber` to align the MailWizz directories with CrewAI. This keeps your MailWizz lists clean without developers writing custom cron jobs for CrewAI.

Let CrewAI agents analyze subscriber list health

Inspect your MailWizz audience metrics directly using the `get_list_details` tool with CrewAI. This MCP Server setup lets your CrewAI agent act on actual data pulled straight from the MailWizz API, minimizing manual export tasks. The CrewAI agent writes report summaries of MailWizz data and suggests changes to your marketing team.

Setup guide

Set up MailWizz 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 MailWizz tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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