How to Use the 4D MCP in CrewAI

Q: Does CrewAI support selective tool access for 4D?

You use toolfilter to limit which agent can execute write operations. This prevents unauthorized agents from changing your database records.

Deploy specialized agent crews to monitor and manage your 4D database using collaborative task execution.

CrewAI agents managing 4D records

Assign a researcher agent to use `list_entities` for finding stale data. A second agent then triggers `delete_entity` to prune the database. Your crew shares memory to track which records require attention. They collaborate to ensure the database stays accurate.

Collaborative 4D updates in CrewAI

Let your monitor agent call `get_entity` to verify current values. If the data deviates from your baseline, a manager agent runs `update_entity`. This keeps your system state correct without constant human oversight. The agents pass the JSON payloads between them during the task flow.

Schema-aware CrewAI operations

Provide `get_catalog` access so your agents understand the database structure. They learn the field requirements before attempting to `create_entity`. Your crew operates with full visibility into the table definitions. It prevents malformed data from ever hitting your 4D instance.

Setup guide

Set up 4D 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 4D tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="4D Analyst",
    goal="Access and analyze 4D data via MCP.",
    backstory="Expert analyst with direct 4D access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent 4D 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="4D Analyst",
        goal="Access and analyze 4D data via MCP.",
        backstory="Expert analyst with direct 4D access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent 4D transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about 4D MCP in CrewAI

You pass the server URL into the agent configuration. The agents automatically discover the available tools and coordinate their use.

Yes, you can define a hierarchical execution flow. One agent queries the records while another processes the updates sequentially.

Vinkius manages all transport security via an ephemeral token. Your database access is restricted to the specific agents in your crew.

You use tool_filter to limit which agent can execute write operations. This prevents unauthorized agents from changing your database records.

The agent reports the error back to the crew lead. You can then trigger a secondary agent to handle the failure or escalate to a human.
