How to Use the Zippopotam.us Alternative MCP in CrewAI

Q: Can CrewAI find all zip codes for a city using Zippopotam.us Alternative?

Yes, you assign an agent the task of calling getpostalcodesbycity with defined city and state parameters. The agent then shares that resulting list with other crew members.

Specialized Location Research Agents

You assign roles to your agents. One agent can be the 'Researcher' that calls `get_postal_codes_by_city` to gather a list of zip codes for a given area. A second agent, the 'Validator,' then takes that resulting list and uses `get_location_by_postal_code` to get detailed coordinates.

Autonomous Data Collection Chains

CrewAI runs these tasks sequentially. The 'Monitor' agent watches the session, ensuring the output from gathering zip codes is passed correctly as input for location lookups. This creates an automated pipeline that requires zero human intervention once launched.

Role-Based Tool Exposure

You can use `tool_filter` to ensure only the necessary tools are exposed. For instance, if you only want coordinate lookups, you expose *only* `get_location_by_postal_code`. This keeps your crew's focus narrow and prevents agents from calling unnecessary geocoding functions.

Setup guide

Set up Zippopotam.us Alternative 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 Zippopotam.us Alternative tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

    task = Task(
        description="List recent Zippopotam.us Alternative transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about Zippopotam.us Alternative MCP in CrewAI

You pass the MCP Server URL directly to your crew setup. Agents use this server's tools—like finding location by postal code—as specialized functions in their operational roles.

Yes, you assign an agent the task of calling `get_postal_codes_by_city` with defined city and state parameters. The agent then shares that resulting list with other crew members.

The server handles public geo-spatial metadata: postal codes, city names, state abbreviations, and coordinates. The agents process this data through shared memory.

Yes. You build error handling into the agent's task description. If an expected zip code lookup fails, a moderator agent can be tasked with notifying another specialist to take over.

The server touches public geo-spatial metadata: postal codes, city names, and coordinates. Since the agents process this data in shared memory, you're dealing only with structured strings.
