How to Use the Mailinator MCP in CrewAI

Q: How do I add the Mailinator MCP Server to a CrewAI agent?

Pass the server URL directly into the mcps list when defining your agent. CrewAI automatically discovers and loads the available endpoints.

Q: Can different CrewAI agents use different Mailinator MCP tools?

Yes. Use the MCPServerHTTP class with a toolfilter. You can give the testing agent access to injecttestmessage and the cleanup agent access to removemessage.

Q: Can a CrewAI agent read SMS messages via Mailinator?

Yes. Just expose the listprivatesms tool. The agent grabs the text message and passes the contents to the next agent in the sequence.

Delegate Email Testing to CrewAI

Watching a disposable inbox during automated runs relies on the `list_inbox_messages` tool. You do not need to write massive procedural test scripts. Assign one agent to act as the sender and another as the verifier. The verifier agent reads the payload using `get_message_content`. If the formatting is wrong, it immediately reports the bug back to the crew manager.

Audit Attachments and Webhooks

Confirming your system generated the correct file exports uses the `list_message_attachments` tool. Compliance testing often requires verifying PDF receipts. A specialized auditor agent handles this step automatically. Another agent can monitor your notification pipelines. By running `list_active_webhooks`, it checks if your alerting system is configured properly before the crew runs a simulated attack.

Monitor Usage and Domain Health

Monitoring your API limits during long runs requires the `get_usage_statistics` tool. Autonomous sessions can burn through quotas fast. Set up a monitor agent that periodically checks usage and pauses the operation if needed. The same agent can keep track of available testing environments. It runs `list_private_domains` to ensure the crew is routing test traffic to active, valid addresses.

Setup guide

Set up Mailinator 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 Mailinator tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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