Perplexity

Multi-step hardware sequences with Mastra AI

Mastra AI workflows sequence the `alarm_action` and `cover_action` tools to lock down a building based on custom conditional logic. If the initial API call fails due to network latency, the framework automatically retries with exponential backoff. When a `switch_action` times out, the agent catches the error immediately. It logs the failure and attempts a secondary protocol without requiring human intervention.

Granular state verification via MCP Server

This MCP Server exposes `get_entity_state` so your agent can verify a physical action actually occurred. It triggers a relay, waits two seconds, and polls the API to confirm the door sensor registers as closed. Relying on fire-and-forget commands causes hardware sync issues, so the agent checks `get_entity_state` first. It decides if the action is necessary and only fires `button_press` if the current state requires it.

Automated hardware tuning

The `number_set` and `select_option` tools let your workflow adjust operational parameters on the fly. If the metrics show the CPU running hot, the agent lowers the polling frequency by updating the select entity. Your logic monitors environmental changes over time using `get_metrics`. The agent reads a temperature spike and immediately adjusts the cooling system via `fan_action` before alerting the administrator.

Setup guide

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

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

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

Common questions about ESPHome MCP in Mastra AI

Install @mastra/mcp and initialize the MCPClient with your server URL. You then spread listTools() into your agent's tool array.

Yes. You configure requireToolApproval on the specific tool. The workflow pauses, waits for an administrator to click approve, and then flips the physical relay.

The framework catches the HTTP error from the MCP server. You configure exponential backoff rules in your workflow to retry the connection automatically.

No. The Mastra client auto-detects whether the server uses Server-Sent Events or Streamable HTTP and connects accordingly.

The tools transmit raw sensor values and local IP addresses. Vinkius enforces a zero-trust architecture, destroying the execution environment immediately after the workflow step completes, leaving no persistent logs of your home network.
