How to Use the NumVerify MCP in CrewAI

Specialized verification agents

Assign a 'Data Auditor' agent to use `validate_phone` on your new signups. This agent acts as a gatekeeper, ensuring only valid numbers proceed to your core crew. It works in the background while your other agents focus on engagement. This separation of concerns keeps your operations clean.

Carrier analysis for your crew

Have your 'Market Research' agent call `get_phone_carrier` to understand your lead's network provider. This helps your crew tailor their communication strategy. It gives your agents the context they need to act intelligently. They don't just process numbers; they understand them.

Geographic monitoring with the NumVerify MCP Server

Use `get_phone_location` to feed your 'Compliance' agent accurate geographic data. The agent monitors for signups originating from forbidden locations. It provides a persistent check on your user base. Your crew stays updated on where your traffic is coming from.

Setup guide

Set up NumVerify 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 NumVerify tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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