How to Use the Mercado Livre Catalog MCP in CrewAI

Q: Can I limit which tools on this MCP Server a specific CrewAI agent can use?

Yes. You can use the MCPServerHTTP class with a tool filter to restrict access. For instance, you can let your writer agent use getcategories while restricting deleteitem to your manager agent.

Q: What is the best way to run this MCP Server with a CrewAI team?

You can pass the Vinkius URL directly in your Agent's mcps configuration array. CrewAI handles the connection, exposing the MCP tools directly to your specialized agents.

Perplexity

Coordinate inventory updates across specialized agents

Managing a large store requires division of labor. With CrewAI, you can set up a pricing agent that monitors competitor rates and a stock agent that tracks warehouse levels, both working in parallel. The pricing agent uses `update_price` to adjust margins, while the stock agent calls `update_stock` to prevent overselling. They coordinate their actions through shared memory, ensuring your storefront never shows conflicting details.

Onboard new products autonomously with this MCP Server

Adding new items doesn't have to be a manual chore. This MCP Server allows your writer agent to draft SEO-friendly titles while your compliance agent calls `get_domain_attributes` to verify technical requirements. Once both agents agree the payload is perfect, a publisher agent calls `create_item` to push the listing live. This multi-agent verification pipeline eliminates formatting errors before they hit the marketplace.

Audit active listings via multi-agent collaboration

Keep your listings accurate without lifting a finger. Your CrewAI audit team can run background sweeps, using `search_items` to find listings and `get_item` to verify their active details. If the audit agent finds an error or an outdated description, it hands the task to an editor agent to run `update_item`. Your catalog stays clean, compliant, and optimized around the clock.

Setup guide

Set up Mercado Livre Catalog 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 Livre Catalog tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Mercado Livre Catalog MCP in CrewAI

Your agents share a common memory pool. When one agent runs `update_stock`, the rest of the crew instantly knows the new inventory level, preventing duplicate calls to the API.

Yes. You can use the `MCPServerHTTP` class with a tool filter to restrict access. For instance, you can let your writer agent use `get_categories` while restricting `delete_item` to your manager agent.

The server manages authentication at the endpoint level using a secure token. Your agents simply invoke tools like `update_price` without needing to handle OAuth handshakes themselves.

You can pass the Vinkius URL directly in your Agent's `mcps` configuration array. CrewAI handles the connection, exposing the MCP tools directly to your specialized agents.

All API calls to update prices or stock run inside sandboxed V8 isolates. We never write your store's private catalog data to disk, and all credentials are encrypted in transit using industry-standard protocols.
