How to Use the Mailingwork MCP in CrewAI

Q: How do I expose the Mailingwork MCP Server to my CrewAI agents?

Install crewaitools and pass your Vinkius endpoint directly into the agent definition using mcps="https://...". The agent automatically registers the available marketing functions.

Q: Can I restrict which CrewAI agents use Mailingwork tools?

Yes. Use MCPServerHTTP from crewai.mcp and apply a toolfilter. You can give your reporting agent read-only access while letting your execution agent create subscribers.

Deploy autonomous marketing teams via the MCP Server in CrewAI that monitor Mailingwork metrics and adjust campaigns without human input.

Deploy an Autonomous Mailingwork MCP Server Crew

Give your reporting agent access to the `list_mailings` and `get_mailing` tools to constantly monitor campaign performance. It pulls data into the crew's shared memory, analyzing open rates and click-throughs against historical baselines. When it detects a drop in engagement, it alerts an optimization agent. That second agent evaluates the segment logic and proposes adjustments to the active sequences.

Manage List Hygiene Automatically

Assign a specialized list manager agent the `list_subscribers` and `update_subscriber` tools. It scans your database for unengaged contacts and applies a suppression tag based on your predefined rules. You run this process hierarchically. A manager agent oversees the cleanup task. It ensures the worker agent validates the subscriber status with `get_subscriber` before making any permanent changes.

Execute Complex A/B Test Rollouts

Combine `list_lists` and `trigger_automation` to launch targeted experiments. An agent splits a specific audience segment, initiates an A/B test via automation, and waits for statistical significance. Once the results stabilize, a decision agent evaluates the winning variant. It then deploys the successful content to the remainder of the list automatically.

Setup guide

Set up Mailingwork 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 Mailingwork tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Mailingwork MCP in CrewAI

Install `crewai[tools]` and pass your Vinkius endpoint directly into the agent definition using `mcps=["https://..."]`. The agent automatically registers the available marketing functions.

Yes. Use `MCPServerHTTP` from `crewai.mcp` and apply a `tool_filter`. You can give your reporting agent read-only access while letting your execution agent create subscribers.

The agent reads the error message returned by the MCP endpoint. It uses its internal reasoning loop to adjust parameters and retry the request without crashing the entire crew session.

Yes. You configure an agent to listen for system alerts and call `send_transactional_email`. It formats the payload and dispatches the message to the specified recipient.

Vinkius routes all requests through an ephemeral, isolated container. When your agents query subscriber names and GDPR consent statuses, the memory layer drops the data the second the connection terminates.
