How to Use the Karbon MCP in CrewAI

Q: How do I hook up Karbon to my CrewAI agents?

Pass the MCP Server URL straight into the mcps array on your Agent definition. For granular control, import MCPServerHTTP and use a tool filter.

Q: Can I restrict which CrewAI agents update Karbon records?

Absolutely. Give your reader agents access to listcontacts and getworkitem. Only give your action agents the updateworkitem tool.

Q: How does CrewAI handle creating new Karbon contacts?

Your intake agent calls createcontact with a name and type. It handles the JSON payload internally based on the conversation context.

Q: What is the best way to assign tasks to firm members?

Have your manager agent run listusers. It reads the firm directory and assigns the resulting IDs to new projects.

Deploy a specialized crew of autonomous agents to manage your Karbon accounting firm operations with CrewAI.

Autonomous Karbon MCP Server Operations

The `list_work_items` tool gives your manager agent a complete view of the firm's active jobs. This agent delegates specific checks to worker agents. One worker investigates stalled projects while another flags missing documentation. Deep dives happen when a worker agent calls `get_work_item` and `list_work_tasks`. The agent reads the exact state of a tax return. It passes that context back to the manager to decide if the client needs a follow-up call.

Map Organizations and People

The `list_organizations` and `list_people` tools let your research agent map out complex corporate structures. It pulls the data apart, identifying which individuals belong to which holding companies. You get a clean hierarchy without manual sorting. Digging into client history is a job for `list_contact_notes`. The agent reads years of communication logs. It hands a summary to your drafting agent to prepare the annual review meeting agenda.

Execute Updates Across the Firm

The `update_work_item` tool allows your moderator agent to move projects forward automatically. When the research agent confirms a task is done, the moderator updates the status in the database. Zero human clicks required. Onboarding kicks off with `create_contact` and `create_work_item`. A specialized intake agent receives a new client email, creates the organization record, and spins up the initial bookkeeping project. Your team just watches the dashboard populate.

Setup guide

Set up Karbon 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 Karbon tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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