How to Use the REST Countries MCP in CrewAI

Q: How do CrewAI agents handle invalid country names in REST Countries?

If getcountrybyname returns no results, your researcher agent can flag the error. A corrector agent can then attempt to resolve the issue using getcountrybycode.

Q: Can I limit which REST Countries tools a CrewAI agent can use?

Yes, you can use the toolfilter option to restrict which MCP tools are exposed to specific agents. For instance, you can limit a financial agent to only use getcountriesbycurrency.

Collaborative global research with CrewAI teams

The `get_all_countries` tool provides your CrewAI research agents with a complete starting index for global market analysis. One agent can pull the entire country list while a secondary analyst agent filters the results based on economic criteria. This collaborative setup allows your crew to divide and conquer massive datasets. By sharing memory, the agents avoid redundant calls and coordinate their tasks to build a cohesive global report.

Targeted regional analysis using CrewAI specialized agents

Use `get_countries_by_region` to assign specific territories to different agents in your CrewAI setup. A European specialist agent can focus on EU records while an Asian specialist queries eastern subregions simultaneously. You can also deploy `get_countries_by_language` to group agents by linguistic boundaries. This specialization ensures that your autonomous crew processes regional data with deep contextual accuracy.

Automated verification of country codes and currencies

The `get_country_by_code` tool enables a supervisor agent to audit data entered by other crew members. They validate ISO codes against the live database to ensure zero formatting errors in your reports. When parsing financial documents, your CrewAI agents use `get_countries_by_currency` to cross-reference currency codes with geographic regions. If `get_country_by_name` returns a mismatch, the moderator agent flags the record for manual review.

Setup guide

Set up REST Countries 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 REST Countries tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about REST Countries MCP in CrewAI

Pass the Vinkius endpoint URL directly to load the MCP Server into your agent's configuration. The agent immediately gains access to tools like `get_all_countries` for autonomous research.

Yes, CrewAI manages tool access across your entire crew. Agents can call `get_countries_by_region` concurrently while sharing the results through their common memory.

If `get_country_by_name` returns no results, your researcher agent can flag the error. A corrector agent can then attempt to resolve the issue using `get_country_by_code`.

Yes, you can use the `tool_filter` option to restrict which MCP tools are exposed to specific agents. For instance, you can limit a financial agent to only use `get_countries_by_currency`.

Your queries regarding country profiles, language demographics, and currency codes run in a zero-trust environment. The V8 sandbox ensures that all execution data is destroyed the moment the crew completes its task.
