Specialized email monitoring with CrewAI

Assign a monitor agent to watch your inbox using `list_server_messages`. When a new email hits the server, the agent flags it for analysis. This separates the task of waiting for mail from the task of verifying its contents. Your crew stays organized and focused on their specific roles.

Autonomous verification cycles

Use `get_message_content` to have your analyst agent extract codes from emails. This tool provides the raw data your agents need to pass or fail a test. Your agents don't need a human to read the inbox. They pull the content, check the validity, and move to the next task automatically.

Clean state enforcement

Ensure your crew starts with a blank slate by using `clear_server_inbox`. It’s a simple way to reset the environment for the next round of testing. Your agents can run this as a final step in their sequence. It keeps your test environment predictable and free of leftover noise.

Setup guide

Set up Mailosaur 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 Mailosaur tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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