Automated workflow logic for Mastra AI

Chain your game management tasks using conditional logic. If `validate_login` fails, your agent automatically triggers a retry or notifies the team. This is how you handle failures without manual intervention. The workflow engine keeps everything moving even when specific requests hit a snag.

Multi-step leaderboards for Mastra AI agents

Set up agents that monitor and update player rankings. Your agent uses `get_leaderboard` to fetch data and then routes the output to your database. It handles the heavy lifting of sorting and recording player progress. You define the logic, and the agent executes the sequence.

Secure player interactions in Mastra AI

Filter incoming content before it hits your game logs. You use `check_sensitive_words` to sanitize text input from your players. This protects your community from bad actors. Your agent runs the check as part of a larger cleanup workflow.

Setup guide

Set up 4399 Open Platform 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 4399 Open Platform 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: "4399-open-platform-mcp-client",
  servers: {
    "4399-open-platform-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "4399 Open Platform Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to 4399 Open Platform tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent 4399 Open Platform transactions"
);
console.log(result.text);
