Branching Logic for AWS Events

The `put_events` tool lets your agent trigger backend workflows based on conditional logic. Mastra AI evaluates user input and decides if an action is necessary before touching AWS. If a user requests a refund, the agent checks the policy first. If approved, it dispatches the event to your scoped EventBus to kick off the financial process.

Built-in Retries for your MCP Server

Connecting this MCP Server to your agent gives you automatic exponential backoff for AWS dispatches. Cloud networks fail. That's just reality. But your system handles it right out of the box. If AWS throttles your request or the connection drops during a dispatch, Mastra tries again. Your critical backend triggers won't get lost due to transient network blips.

Human-in-the-Loop Dispatching

Staging the `put_events` payload for human review prevents autonomous mistakes. Firing events into a production bus carries serious consequences. Enable requireToolApproval in your configuration. The agent will prepare the event and wait for a human operator to click approve before anything hits AWS.

Setup guide

Set up Amazon EventBridge Bus 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 Amazon EventBridge Bus 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: "amazon-eventbridge-bus-mcp-client",
  servers: {
    "amazon-eventbridge-bus-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Amazon EventBridge Bus MCP in Mastra AI

Install @mastra/mcp and instantiate a new MCPClient. Pass your Vinkius URL into the servers object, then call listTools() to spread them into your agent.

Yes. The workflow engine catches any errors returned by the tool. You can configure conditional branches to notify an admin if an event fails to dispatch.

Mastra automatically detects the transport type from the URL. It handles both Streamable HTTP and SSE connections for this server without extra configuration.

Limiting the scope enforces zero-trust architecture. If an agent goes rogue or hallucinates, it can only push data to the specific queue you authorized.

We run your requests through ephemeral V8 isolates. The JSON payloads you send are processed in a temporary memory space that vanishes the millisecond the AWS API responds.
