Assign BigMailer tasks to your CrewAI agents

Give your research agent access to `list_contacts` while your moderator agent handles `add_contact` updates. This division of labor keeps your marketing tasks focused and efficient. Agents share memory of the state. If one agent finds a new lead, the next one can process it without asking for the same data twice.

Monitor campaigns with a CrewAI crew

Set a monitor agent to watch `list_bulk_campaigns` for performance dips. When the agent detects an issue, it can alert another member of the crew to investigate further. It handles the heavy lifting of campaign oversight. You define the roles, and the agents handle the routine checks and balances.

Sync brand assets with CrewAI

Use `list_templates` to let your design-focused agent audit your available email layouts. It ensures that every campaign message follows your current brand guidelines. This keeps your brand voice consistent. The agent checks the available templates before drafting new content, preventing outdated styles from slipping into production.

Setup guide

Set up BigMailer 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 BigMailer tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about BigMailer MCP in CrewAI

Pass the server URL to the agent's MCP configuration. CrewAI will register the tools, allowing your agents to interact with your account.

Yes, the agents use shared memory. One agent fetches the contact list, and the other can immediately act on that data.

It does. You can assign specific tools to specific agents in your hierarchy, ensuring only the right agent can modify your mailing lists.

Use the tool_filter option in your agent config. This limits the agent to only the functions you want it to perform.

All interactions happen through a secure, ephemeral tunnel. Your subscriber names and email data are never stored by the server, and access is restricted to the specific task at hand.
