Assign MCP Tools to CrewAI Agents

`calculate_cash_conversion_cycle` gives your research agent the raw cycle duration. The agent feeds in inventory, receivables, and payable days. It gets back the exact number of days cash is trapped in the business. Your analyst agent uses this number to flag operational bottlenecks. If the cycle spikes, the agent writes a report detailing where the cash is stuck. CrewAI passes the context to the next agent in the sequence.

Share Monetary Values in Agent Memory

`calculate_monetary_working_capital` hands the dollar value to your treasury agent. The agent takes the cycle days and company turnover to compute the actual cash need. This agent then decides if you need to draw on your credit facility. The treasury agent operates independently from the analyst. It focuses purely on liquidity and funding decisions. CrewAI manages the shared memory so both agents stay aligned on the financial reality.

Moderate Full Summaries Hierarchically

`get_financial_cycle_summary` provides the moderator agent with the complete financial profile. The moderator reviews every constituent period and the final calculated values. It uses this full context to escalate issues to the human CFO. This hierarchical execution keeps your autonomous operations in check. The moderator doesn't act on partial data. It waits for the full summary before triggering any high-level alerts or escalations.

Setup guide

Set up Working Capital Calculator 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 Working Capital Calculator tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Working Capital Calculator MCP in CrewAI

Pass the MCP URL directly into the mcps list when defining your agent. CrewAI handles the HTTP transport and exposes the tools to your agent automatically.

Yes. You can assign different tools to different agents using the tool_filter in MCPServerHTTP. This lets your analyst agent run the cycle calculation while the treasury agent runs the monetary calculation.

CrewAI uses a shared memory system. When one agent executes a tool, the result gets stored in the crew context. The next agent in the sequence can read that result without making a redundant API call.

It supports standard HTTP, Server-Sent Events, and Streamable HTTP. CrewAI auto-detects the protocol based on the URL you provide in the agent configuration.

The MCP transmits days inventory outstanding, days sales outstanding, days payable outstanding, and total turnover. Your agents only receive the calculated days and dollar amounts back.
