How to Use the Plasmic (Visual Headless Page Builder) MCP in Mastra AI

Q: Can Mastra AI handle conditional publishing with Plasmic (Visual Headless Page Builder)?

Yes, you can build a Mastra AI workflow that runs updatecmsitem and only calls publishcmsitem after specific validation steps succeed. This ensures no broken drafts hit your live site.

Q: How do I require human approval before Mastra AI modifies Plasmic (Visual Headless Page Builder) assets?

Enable the requireToolApproval setting on your Mastra AI agent. This pauses execution and prompts you for verification before the agent can run destructive tools like deletecmsitem on your visual builder CMS.

Automated CMS publishing pipelines with this MCP Server

The `create_cms_item` tool inserts new records directly into your visual builder's database. Mastra agents use this to automatically structure incoming raw text into clean CMS items. If the insertion fails, the framework's workflow engine triggers automatic retries with exponential backoff. You don't have to write custom error-handling loops for your content pipeline.

Conditional branching for visual updates

The `update_project` tool modifies page layouts and component configurations programmatically through this MCP Server. Your workflow evaluates external conditions before deciding to push layout updates. For instance, if a marketing campaign hits its target, the agent automatically swaps the hero banner. You define the logic, and the agent handles the visual changes.

Clean draft lifecycle management

The `publish_cms_item` tool pushes draft updates live to your production site. Your workflow ensures content passes human-in-the-loop approval before calling this endpoint. You maintain total control over what goes public. The agent stages the content, waits for your green light, and deploys the changes instantly.

Setup guide

Set up Plasmic (Visual Headless Page Builder) 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 Plasmic (Visual Headless Page Builder) 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: "plasmic-visual-headless-page-builder-mcp-client",
  servers: {
    "plasmic-visual-headless-page-builder-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Plasmic (Visual Headless Page Builder) transactions"
);
console.log(result.text);
