Role-based email operations in CrewAI

Assign specific tasks to your agents using `list_email_campaigns` and `get_campaign_details`. One agent researches campaign performance while another summarizes it for your review. Specialized agents work better. By splitting the work, your crew handles complex email tasks without human oversight.

Autonomous subscriber list maintenance in CrewAI

Let your maintenance agent call `update_list_subscriber` to keep your CRM data clean. The agent monitors incoming data and applies updates as needed. Your list stays current without manual intervention. The crew handles the sync logic based on the parameters you provide at the start of the mission.

Scale email campaigns with CrewAI agents

Run multiple instances of `create_new_campaign` across your crew to manage high-volume email efforts. Agents handle the drafting and dispatching in parallel. Efficiency increases when agents work together. Your crew coordinates the campaign lifecycle from draft to final send while you watch the results.

Setup guide

Set up Mail Blaze 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 Mail Blaze tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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