How to Use the Unit & FX Calculator MCP in CrewAI

Q: Can Unit & FX Calculator support autonomous operations with CrewAI?

Yes. Your crew can use convertunit and getrate. The tools provide deterministic math, meaning the agents don't rely on general LLM knowledge for accurate calculations.

Q: How does Unit & FX Calculator assist with data analysis in CrewAI?

The 'Analyzer' agent uses batchconvert to process multiple measurements at once, giving the team a reliable and efficient way to handle bulk unit adjustments across different documents.

Deterministic Math for Agent Roles

When your crew needs to calculate something physical, the 'Analyzer' agent calls `convert_unit`. This tool converts units like Celsius to Fahrenheit deterministically, stopping the team from using hallucinated math. It keeps all specialized agents focused on their roles while providing rock-solid data inputs.

Live Rate Checking for Research Agents

If a research agent needs current financial data, it uses `get_rate` to pull the exact foreign exchange rate between currencies. The 1h cache keeps the operation fast and reliable. This prevents your autonomous crew from making decisions based on stale or incorrect market rates.

Processing Large Data Sets in Batches

The 'Operations' agent uses `batch_convert` to process large datasets of measurements. This tool accepts values, source units, and target units for conversion in a single pass. It’s an efficient way to handle bulk data without needing multiple sequential steps in the workflow.

Setup guide

Set up Unit & FX 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 Unit & FX Calculator tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

    task = Task(
        description="List recent Unit & FX 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 Unit & FX Calculator MCP in CrewAI

Yes. Your crew can use `convert_unit` and `get_rate`. The tools provide deterministic math, meaning the agents don't rely on general LLM knowledge for accurate calculations.

The 'Analyzer' agent uses `batch_convert` to process multiple measurements at once, giving the team a reliable and efficient way to handle bulk unit adjustments across different documents.

The server manages both physical measurements (like weight or temperature) and financial values, specifically the currency pairs required for exchange rate lookups via `get_rate`.

It is. The tools are deterministic; they don't guess. They use defined math libraries to convert units or pull live rates, ensuring high accuracy across all autonomous agent actions.

The server requires structured numerical values, source/target unit strings, and standard ISO 4217 currency codes for both conversion and rate lookup tools.
