How to Use the Amazon S3 Bucket MCP in Mastra AI

Q: Can I audit Amazon S3 Bucket access in Mastra AI?

You can use getbucketpolicy to inspect current settings before your agent runs. Mastra AI reports these findings so you can verify compliance in real-time.

Q: Can Mastra AI list files in an Amazon S3 Bucket by folder?

Absolutely, just set the delimiter in listobjects. Mastra AI parses the prefix to navigate your bucket structure like a local file system.

Perplexity

Automated file management for Mastra AI

Chain `list_objects` and `delete_object` to build cleanup routines that run automatically. Mastra AI retries these calls if the network blips. This keeps your storage tidy without manual intervention. You define the workflow, and the agent handles the execution logic.

Conditional data processing in Mastra AI

Check `get_bucket_acl` before your agent attempts to read sensitive files. If the policy blocks access, the agent branches to a fallback step. This prevents runtime errors during complex tasks. Your Mastra AI agent knows exactly when to stop and alert you.

Deploying Amazon S3 Bucket tools with Mastra AI

Integrate `put_object` into your agent's toolset to save results back to your storage. It works inside any cloud environment you deploy to. Everything stays consistent. Your agent treats the bucket as a reliable persistent memory layer for multi-step tasks.

Setup guide

Set up Amazon S3 Bucket 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 S3 Bucket 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-s3-bucket-mcp-client",
  servers: {
    "amazon-s3-bucket-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Amazon S3 Bucket Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Amazon S3 Bucket tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Amazon S3 Bucket transactions"
);
console.log(result.text);
