How to Use the Factorial MCP in Mastra AI

Q: Can I require human approval before Mastra AI views Factorial contracts?

Yes. You can configure the agent with requireToolApproval for sensitive actions. This ensures the agent cannot run listemployeecontracts without explicit confirmation from an HR manager.

Build resilient Mastra AI workflows that automatically audit Factorial payroll contracts and track team shifts without failing.

Automate compliance reviews by running contracts

Automate compliance reviews by running `list_employee_contracts` on a scheduled Mastra AI workflow. By connecting this MCP Server to Mastra AI, you build a workflow that automatically triggers on the first of the month to check every active agreement. The agent runs the query to find expiring terms and flags them for review. If the API call fails due to a network hiccup, Mastra's built-in workflow engine retries with exponential backoff. It ensures your compliance audits finish successfully without human intervention, even if the external platform experiences brief downtime.

Monitor attendance patterns inside multi-step workflows

Monitor attendance patterns automatically using `list_attendance_shifts` inside multi-step workflows. Your Mastra agent queries the attendance logs and cross-references the data against scheduled time off retrieved via `list_time_off_leaves`. If a discrepancy is found, the workflow initiates a conditional branch. It automatically looks up the manager's info using `get_employee_details` and prepares a draft notification, executing the entire sequence reliably under a single deployment.

Build structured document workflows with this MCP Server

Navigate your document library using `list_document_folders` within autonomous workflows. With this MCP Server connected, you build an agent that navigates your library and catalogs files with `list_hr_documents` automatically. Set up strict execution rules where the agent must get human approval before moving files or changing access rights. It gives you complete control over your organizational data while letting the agent do the heavy lifting of sorting through team files.

Setup guide

Set up Factorial 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 Factorial 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: "factorial-alternative-mcp-client",
  servers: {
    "factorial-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Factorial MCP in Mastra AI

Mastra AI uses a built-in workflow engine with automatic retries and exponential backoff. If a call to `list_employees` drops, the system pauses and retries the request until it succeeds.

Yes. You can configure the agent with `requireToolApproval` for sensitive actions. This ensures the agent cannot run `list_employee_contracts` without explicit confirmation from an HR manager.

You can deploy your Mastra agent to any cloud provider with a single command. The agent connects to the hosted MCP endpoint, triggering tools like `list_company_teams` from any serverless environment.

Absolutely. You build a multi-step workflow that pulls pending requests using `list_time_off_leaves` and passes that data to external calendar tools using Mastra's conditional branching logic.

Yes. All communication between Mastra and the MCP server uses secure, encrypted transport protocols. Your attendance logs and shift records are processed on the fly and are never cached or stored in any external database.
