How to Use the Mercado Libre MCP in CrewAI

Q: How do CrewAI agents coordinate when responding to Mercado Libre questions?

Your monitoring agent uses searchquestions to find unanswered queries. It passes the text to a writer agent to draft a response, which then uses answerquestion to post the final reply.

Q: Can I limit which tools my agents can execute?

Yes. You can use the toolfilter configuration in CrewAI to expose only a subset of the 17 available MCP tools, ensuring your agents never perform unauthorized actions.

Q: How does this MCP Server protect Mercado Libre customer addresses?

All calls to getuseraddresses are executed within secure, single-use sandboxes. No customer location data or shipping addresses are cached, ensuring absolute compliance with regional data privacy laws.

Deploy a collaborative crew of specialized agents to run your Mercado Libre operations autonomously using CrewAI.

Resolve Buyer Issues Autonomously with CrewAI

`get_claim` acts as the primary data source for your CrewAI dispute resolution agent. While one specialized agent analyzes the claim details, a second agent uses the shared memory to check the buyer's purchase history. Once the team agrees on the resolution, the acting agent invokes `send_post_sale_message` to explain the outcome to the buyer. This multi-agent collaboration ensures that refunds and returns are handled with deep contextual awareness rather than simple keyword matching.

Run Your Catalog via this MCP Server

`get_sale_price` allows your pricing analyst agent to monitor current listing costs against your target profit margins. The agent works alongside a catalog manager agent to decide if a listing needs a price adjustment. If the catalog agent identifies a gap, `create_item` is called to launch alternative listings or update existing ones. Your entire inventory strategy runs on autopilot, with agents coordinating to keep your store competitive.

Track Deliveries with Autonomous Logistics Agents

`get_shipment` provides your logistics agent with real-time transit status for every open order. A dedicated monitoring agent tracks these updates and flags any package that has stalled in transit. When a delay is detected, the agent pulls the delivery commitments using `get_shipment_sla`. The crew then coordinates to draft a proactive update, reassuring the buyer before they have a chance to open a dispute.

Setup guide

Set up Mercado Libre 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 Mercado Libre tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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