Collaborative data flattening for agents

Give your CrewAI agents the `transform_dot_object` tool so they can flatten nested data for shared memory. This allows agents to work on the same dataset even if it originally arrived in a deeply nested format. It ensures that every agent in the crew sees the same flattened structure. This prevents communication gaps when agents pass information back and forth during a task.

Unflattening for specialized agent tasks

Some agents in your crew may require specific nested JSON formats to perform their analysis. Use `transform_dot_object` to reconstruct these structures from a flat data source on the fly. This flexibility allows you to mix and match agents with different input requirements in the same crew. The tool handles the mapping, so the agents can focus on their core roles.

Autonomous data formatting

With this tool, your agents can autonomously decide when to flatten or unflatten data during their execution cycle. They no longer need human intervention to fix data format mismatches between tools. It makes your automated operations more resilient. The crew can handle unexpected data shapes without stalling, maintaining the flow of your autonomous processes.

Setup guide

Set up Dot Object Transformer 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 Dot Object Transformer tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Dot Object Transformer MCP in CrewAI

Add the server URL to your agent's MCP list in the CrewAI configuration. Once added, the `transform_dot_object` tool becomes available for the agents to use.

Yes, you can assign the tool to multiple agents in your crew. They can all use it to transform data as needed throughout the execution of their tasks.

It is highly efficient, processing transformations in milliseconds. This is ideal for crews where agents need to exchange data quickly to coordinate their actions.

You can use tool filtering in your CrewAI setup to limit access. Only agents that actually need to perform transformations will have the tool in their inventory.

The server is completely ephemeral and does not retain any of the JSON objects it processes. It operates in a sandboxed environment, ensuring that your agent's data remains isolated.
