Specialized agents for email monitoring

Assign one agent to `list_all_inboxes` while another processes the content. This division of labor keeps your CrewAI agents focused on specific tasks. It makes your autonomous operations much faster. One agent watches for incoming mail while the other handles the verification logic.

Collaborative testing with MailSlurp

Agents share memory to track which inbox belongs to which test case. Using `list_inbox_emails`, the crew can correlate activity across multiple accounts simultaneously. This ensures your agents stay synchronized. They work together to verify that every email reaches its destination without overlap or confusion.

Autonomous cleanup with MailSlurp tools

Set a monitor agent to watch for test completion. Once done, it triggers `delete_specific_inbox` to keep your environment clean and cost-efficient. This prevents resource bloat in your testing infrastructure. The crew manages its own workspace so you don't have to monitor the system manually.

Setup guide

Set up MailSlurp 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 MailSlurp tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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