How to Use the Facturama (SAT) MCP in CrewAI

Q: How does this server protect CFDI files and fiscal records?

All data transmissions, including Base64 files fetched via getinvoicefile, are encrypted in transit. Vinkius executes these tools in isolated, zero-trust environments that immediately destroy session data after execution.

Run autonomous tax crews using this MCP Server

The Facturama (SAT) MCP Server enables multi-agent crews in CrewAI to coordinate complex Mexican billing tasks using the `create_invoice` tool. In a typical setup, an Auditor Agent uses `list_invoices` to scan for pending billing actions, while an Operations Agent calls the creation tool to issue the official CFDI. If a tax code is missing, a CrewAI Catalog Agent queries `list_catalog` and `list_products` to find the correct SAT key. This collaborative approach ensures high accuracy without human supervision.

Monitor SAT compliance status with CrewAI

This MCP Server gives your CrewAI compliance crew direct access to official SAT records via the `get_tax_status` tool. A Compliance Agent runs this tool to verify your company's fiscal standing and uses `list_taxes` to check current tax profiles. If the CrewAI agent detects an issue, it alerts your operations team and pauses automated invoicing to prevent legal penalties. This proactive monitoring protects your business license from regulatory action.

Manage client billing lifecycles autonomously

Use the `create_client` and `get_client` tools within a CrewAI team to onboard new partners without manual data entry. A Registration Agent gathers client details, verifies their RFC, and adds them to the Facturama database. Once the billing cycle ends, a CrewAI Billing Agent issues the invoices and calls `send_invoice_email` to distribute them. If a partner leaves, a Cleanup Agent runs `delete_client` to maintain database hygiene.

Setup guide

Set up Facturama (SAT) 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 Facturama (SAT) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

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

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

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

Common questions about Facturama (SAT) MCP in CrewAI

You assign specific tools to different agents in your crew. For example, one agent uses `get_client` to verify the customer's tax profile, while a billing agent uses `create_invoice` to generate the final CFDI.

Yes. You can configure a dedicated auditor agent with access to `cancel_invoice`. When the agent identifies a billing discrepancy, it cancels the invoice and triggers `send_invoice_email` to notify the client.

You configure the MCP URL in your CrewAI agent definition using a secure Vinkius token. This lets your agents access tools like `list_invoices` without hardcoding API keys in your codebase.

You can prevent this by limiting tool access. Only give your catalog specialist agent access to `list_catalog` and `get_product`, ensuring your billing agent only receives pre-validated tax keys.

All data transmissions, including Base64 files fetched via `get_invoice_file`, are encrypted in transit. Vinkius executes these tools in isolated, zero-trust environments that immediately destroy session data after execution.
