How to Use the Mailshake MCP in CrewAI

Q: How do I connect CrewAI agents to my Mailshake campaigns?

Pass your Vinkius MCP Server URL directly into the mcps list when initializing your CrewAI agents. The agents will automatically discover and use tools like listcampaigns to manage your outreach.

Q: Is it possible to filter which Mailshake tools a CrewAI agent can access?

Yes. You can use the MCPServerHTTP class from crewai.mcp with a toolfilter to restrict an agent's access, ensuring a junior agent cannot run destructive tools like pausecampaign.

Deploy specialized AI crews to research leads, draft emails, and manage Mailshake outreach campaigns autonomously.

Run multi-agent sales operations with CrewAI

Stop forcing a single agent to handle your entire sales cycle. With CrewAI, you can connect your team to our MCP Server and assign a Researcher agent to find leads, while a Manager agent uses `add_prospects` to enroll them into active Mailshake campaigns. A separate analyst agent can monitor campaign performance using `list_campaigns` and `get_campaign_details`. This team-based approach ensures that lead generation and campaign management run as distinct, highly specialized processes.

Autonomous lead triaging and status updates

Set up a dedicated triaging crew that watches your inbox and updates lead stages automatically. One agent reads incoming replies, while another uses `update_lead_status` to mark prospects as won, lost, or ignored based on sentiment. If a prospect requests to opt out, the agent instantly calls `pause_prospect` to stop all future automated follow-ups. This keeps your sender reputation clean without requiring a human to manually flag every reply.

Coordinate team-wide outreach using this MCP Server

Let your CrewAI team manage sales operations across your entire organization. An administrative agent can call `get_team_details` and `get_user_profile` to understand which reps have active capacity before assigning new prospects. The crew can then distribute leads across active campaigns using `list_sales_leads` to balance the workload. This ensures your sales team's output remains steady and avoids overloading any single sender's inbox.

Setup guide

Set up Mailshake 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 Mailshake tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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