How to Use the 123FormBuilder MCP in Mastra AI

Q: How can a Mastra AI agent verify my 123FormBuilder connection?

Your agent can run a quick diagnostic check by calling testformbuilderauth during startup. This ensures your API token is valid before the agent attempts to process any user submissions or modify form structures. If the check fails, the workflow halts immediately to prevent runtime errors.

Q: Can Mastra AI fetch the structural layout of my 123FormBuilder forms?

Yes, your agent can call listformfields to inspect the exact structure of any form in your account. This allows the workflow to understand what fields exist so it can map incoming data to external databases correctly. It eliminates manual mapping work.

Run autonomous multi-step workflows with Mastra AI and the 123FormBuilder MCP Server to handle submissions instantly.

Perplexity

Route 123FormBuilder entries with Mastra AI workflows

You can build complex, multi-step workflows that trigger whenever your agent queries the latest responses with `list_form_entries`. If a submission contains invalid data, the workflow can automatically trigger a retry or flag the issue for human review. This keeps your database clean without requiring you to write custom error-handling loops for every single form.

Monitor active webhook endpoints autonomously

You can set up your agent to inspect your data pipelines by calling `list_form_webhooks`. This setup eliminates silent data drops where webhooks fail without anyone noticing. Your agent can run scheduled checks, verify connection health with `get_api_status`, and keep your data pipelines running smoothly.

Purge outdated form data on a schedule

You can enforce strict data retention policies by letting your agent scan your account using `list_active_forms`. This automated maintenance keeps your storage usage low and helps you comply with privacy regulations. You don't have to log in manually every month to delete old records or clear out test submissions by hand.

Setup guide

Set up 123FormBuilder 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 123FormBuilder 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: "123formbuilder-mcp-client",
  servers: {
    "123formbuilder-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "123FormBuilder Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to 123FormBuilder tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent 123FormBuilder transactions"
);
console.log(result.text);

Common questions about 123FormBuilder MCP in Mastra AI

You register the tools by importing the MCP client wrapper and defining a new `MCPClient` with the Vinkius endpoint. From there, you can fetch the tool list using `mcpClient.listTools()` and spread them directly into your agent's tool configuration. This connects your agent to your workspace in seconds.

Yes, you can configure Mastra to require manual approval before executing tools like `remove_form`. By setting the `requireToolApproval` flag, the workflow pauses and waits for your confirmation before deleting any of your active forms. This prevents accidental data loss during automated runs.

Your agent can run a quick diagnostic check by calling `test_formbuilder_auth` during startup. This ensures your API token is valid before the agent attempts to process any user submissions or modify form structures. If the check fails, the workflow halts immediately to prevent runtime errors.

Yes, your agent can call `list_form_fields` to inspect the exact structure of any form in your account. This allows the workflow to understand what fields exist so it can map incoming data to external databases correctly. It eliminates manual mapping work.

All data processed through the Mastra integration is executed within a secure, ephemeral V8 sandbox. This zero-trust design means your form entries are never cached or saved on external servers. Your credentials and submission details remain completely isolated during execution.
