How to Use the MailerSend MCP in CrewAI

Q: How do I pass MailerSend tools to my CrewAI agents?

Install crewaitools. You can pass the MCP endpoints directly into your agent's mcps array, and the framework automatically registers them.

Q: Can one CrewAI agent send emails while another checks MailerSend stats?

Yes. You use MCPServerHTTP with a toolfilter. You give the sending tools to the action agent and restrict the reporting agent to read-only endpoints.

Perplexity

Run an autonomous MCP Server crew

CrewAI thrives on specialization. You assign one agent to monitor your daily sending quotas using `get_account_limits`. It runs quietly in the background. If you get close to the ceiling, it alerts the rest of the team. A separate response agent handles the actual delivery. It takes the approved copy and executes `send_transactional_email`. The roles stay strictly separated, preventing your monitoring agent from accidentally sending duplicate messages.

Analyze campaign performance automatically

Stop pulling manual reports. Your MCP analytics agent grabs the morning numbers via `get_date_analytics`. It looks at open rates, click tracking, and hard bounces across all active campaigns. If a specific message looks suspicious, the agent digs deeper. It runs `get_message_info` and `list_sent_messages` to isolate the exact recipient. The crew compiles a brief and drops it in your Slack channel before you even finish your coffee.

Monitor domain reputation continuously

Deliverability drops when DNS records drift. You can set up an infrastructure agent to poll `list_sending_domains` every few hours. It checks the verification status of your sender identities. If a domain loses its authenticated status, the crew takes action. It pulls the specific configuration using `get_domain_details` and drafts a ticket for your DevOps team. You fix the issue before emails start landing in spam.

Setup guide

Set up MailerSend 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 MailerSend tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about MailerSend MCP in CrewAI

Install crewai[tools]. You can pass the MCP endpoints directly into your agent's mcps array, and the framework automatically registers them.

Yes. You use MCPServerHTTP with a tool_filter. You give the sending tools to the action agent and restrict the reporting agent to read-only endpoints.

You can configure your crew to require approval before executing specific tools. The agent stops and waits for your confirmation before pushing the payload.

Break the lists down. Have a manager agent delegate batches to worker agents, which then call the sending tools concurrently.

The server processes raw click tracking, bounce logs, and sender domain configurations. Every execution happens in an isolated V8 sandbox that immediately vaporizes after the tool returns the data.
