How to Use the Fundamental Math MCP in CrewAI

Q: How do I add Fundamental Math to CrewAI?

Pass the MCP URL into the mcps parameter of your agent definition. The agent will automatically discover and use the five calculation tools.

Q: Can I restrict Fundamental Math to a specific CrewAI agent?

Yes. Use the MCPServerHTTP class and apply a toolfilter. This lets you assign the math tools exclusively to your quantitative analyst agent.

Give your CrewAI agents deterministic math capabilities. Eliminate LLM hallucinations with a local, zero-latency calculation engine.

Multi-Agent Mathematical Accuracy

The Fundamental Math MCP server equips your CrewAI teams with exact arithmetic tools. When your financial analysis agent needs to compute a compound interest rate, it calls `calculate_power`. The result is deterministic, meaning the agent gets the right answer instead of a probabilistic guess. Multi-agent systems compound errors quickly. If one agent hallucinates a number, the next agent bases its entire analysis on a lie. Giving your crew access to `calculate_percentage` ensures the baseline data remains perfectly accurate across the entire sequential execution.

Role-Based Tool Assignment

CrewAI thrives on specialization. You can restrict this MCP Server to a specific quantitative agent using the `tool_filter` parameter. That agent handles all the `calculate_rule_of_three` requests while the rest of the crew focuses on text analysis or research. This keeps your other agents from getting distracted by math tools they don't need. The quantitative agent processes the numbers locally and passes the exact results into the shared memory pool. The moderator agent simply reads the correct figures.

High-Speed Local Execution

Autonomous operations demand speed. When a data processing agent loops through hundreds of records, calling an external API for `calculate_square_root` or `calculate_factorial` creates massive bottlenecks. This local integration runs locally, returning results in milliseconds. You set this up by passing the MCP URL directly into the `mcps` array of your agent configuration. The Python framework handles the connection automatically. Your crew spends its time reasoning, not waiting for a remote server to multiply two numbers.

Setup guide

Set up Fundamental Math 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 Fundamental Math tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Yes. Use the `MCPServerHTTP` class and apply a `tool_filter`. This lets you assign the math tools exclusively to your quantitative analyst agent.

Agents cannot write and execute native Python safely out of the box. This server gives them a secure, sandboxed way to run deterministic math without code execution vulnerabilities.

No. The calculations happen locally in under a millisecond. It actually speeds up execution by preventing the LLM from wasting tokens trying to reason through arithmetic.

The server processes numerical inputs like numerators and denominators. Vinkius manages the connection, but the ephemeral runtime retains zero state. Your proprietary figures disappear the moment the calculation finishes.
