How to Use the Facturama (SAT) MCP in Mastra AI

Q: How do I set up automatic retries for Facturama (SAT) tools in Mastra AI?

You define a workflow step using the createinvoice tool and configure Mastra's retry parameters. If the SAT API returns a transient error, the workflow retries the operation automatically before triggering any escalation steps.

Q: How can I verify product tax codes before invoicing?

The agent uses listcatalog and getproduct to fetch the correct SAT-approved keys. This verification step runs before createinvoice to ensure every line item complies with Mexican fiscal regulations.

Perplexity

Build self-healing CFDI pipelines

The Facturama (SAT) MCP Server connects tools like `create_invoice` directly to Mastra AI workflows to automate complex billing cycles. If an invoice attempt fails due to a temporary SAT timeout, Mastra AI's built-in retry engine automatically schedules another attempt. If the error persists, the workflow branches to notify your team while using `get_tax_status` to diagnose the issue. This keeps your billing system running without manual intervention during peak tax seasons.

Validate tax profiles using this MCP Server

This MCP Server allows your Mastra AI agents to manage B2B clients autonomously using the `list_clients` and `get_client` tools. The agent calls these tools to audit existing records, verifying that customer tax details match active SAT requirements. When a new client registers, the agent triggers `create_client` to add them to your Mastra AI billing workflow. If a client becomes inactive or fails compliance checks, the workflow executes `delete_client` to keep your records clean.

Automate CFDI audits and cancellations

Use the `list_invoices` tool within a Mastra AI scheduled workflow to run daily audits on your issued tax documents. If the system flags an incorrect invoice, the agent invokes `cancel_invoice` to void the document according to Mexican tax laws. After a successful cancellation, the agent calls `send_invoice_email` to notify the client and update your Mastra AI records. This eliminates manual accounting overhead and avoids costly SAT penalties.

Setup guide

Set up Facturama (SAT) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Facturama (SAT) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "facturama-sat-mcp-client",
  servers: {
    "facturama-sat-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Facturama (SAT) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Facturama (SAT) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Facturama (SAT) transactions"
);
console.log(result.text);

Common questions about Facturama (SAT) MCP in Mastra AI

You define a workflow step using the `create_invoice` tool and configure Mastra's retry parameters. If the SAT API returns a transient error, the workflow retries the operation automatically before triggering any escalation steps.

Yes. Your agent can monitor a database or webhook, identify disputed transactions, and call `cancel_invoice` to void the CFDI. It then uses `send_invoice_email` to deliver the updated status to your customer.

You can use Mastra's tool approval configuration on high-risk tools. For example, you can require manual admin approval before the agent executes `cancel_invoice` or `create_invoice` for large amounts.

The agent uses `list_catalog` and `get_product` to fetch the correct SAT-approved keys. This verification step runs before `create_invoice` to ensure every line item complies with Mexican fiscal regulations.

All client profiles, RFC tax IDs, and billing amounts are processed in zero-trust, ephemeral V8 isolates. Vinkius does not log or persist this sensitive financial information, keeping your operations fully compliant with Mexican data protection laws.
