Autonomous data generation for CrewAI

Equip your research agents with `generate_mock_data` to simulate user activity during long-running tasks. The agent generates the data it needs to perform its analysis without human input. It creates a self-contained environment for your crew. You define the goal, and the agents handle the data acquisition themselves.

Selective tool filtering for your CrewAI agents

Use the tool filter to grant specific agents access to `list_datasets`. You ensure that only the correct agent can pull existing files for processing. It keeps your agent roles specialized and secure. You avoid giving every agent permission to modify or request data they don't need.

Coordinate mock generation across CrewAI teams

Hierarchy-based agents can use `list_schemas` to coordinate the type of data generated for a project. One agent acts as the monitor, ensuring all data conforms to the required standards. This keeps your multi-agent team aligned on the same data architecture. It prevents the drift that happens when different agents use different testing formats.

Setup guide

Set up Mockaroo 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 Mockaroo tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Mockaroo MCP in CrewAI

CrewAI manages the execution order of your agents. You can set them to run sequentially so that each agent's mock data requests don't collide.

Yes, you use the tool filter in your agent configuration. You only pass the specific tools required for that agent's role.

It does. Once an agent generates data, that info can be shared across the crew. This allows the next agent to use the data immediately.

The data is ephemeral and generated on demand. It is not stored on our infrastructure and is only held in memory by your agent process.

The agent reports the failure to the crew lead. You can then program a moderator agent to take over and resolve the issue by querying the schema again.
