How to Use the Holded MCP in Mastra AI

Q: How do I register the Holded MCP server in Mastra AI?

Instantiate a new MCPClient with your endpoint URL. Call mcpClient.listTools() and spread the results directly into your Agent's tool array.

Q: Can Mastra AI require human approval for Holded payments?

Yes. You can set requireToolApproval on tools like createinvoice so a manager reviews the payload before the API executes.

Q: Who can see the Holded purchase orders and expenses pulled by the MCP server?

Nobody. The V8 isolate sandbox processes your listexpenses and listpurchaseorders requests in memory and destroys the environment immediately after routing the data to your client.

Build complex billing workflows and automated retries in Mastra AI using your local Holded MCP server data.

Perplexity

Build Mastra AI billing workflows

Triggering `create_invoice` initiates a sequence that you can wrap in conditional logic. If a client record is missing, your agent catches the error and executes `list_contacts` to search for alternative tax IDs before retrying. You handle failures gracefully instead of crashing the pipeline. The built-in exponential backoff ensures rate limits on the tax reporting endpoints don't break your end-of-month reconciliation.

Sync purchase orders and expenses

The `list_purchase_orders` and `list_expenses` tools give your workflow engine direct read access to outgoing cash flow. You can configure an agent to run daily checks against your approved budget thresholds. When numbers don't match, the agent pulls `list_purchase_invoices` to find the discrepancy. It then formats a report and flags it for human review using the `requireToolApproval` feature in your MCP configuration.

Monitor external webhooks

Calling `list_webhooks` allows your agent to audit which third-party systems are currently listening to your ERP events. You use this to verify that external logistics partners receive shipping updates. If a webhook drops, the agent can alert an admin. You deploy this entire monitoring sequence to any cloud with a single command, keeping your infrastructure footprint small.

Setup guide

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

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

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

Yes. You can set `requireToolApproval` on tools like `create_invoice` so a manager reviews the payload before the API executes.

The framework includes automatic retries with exponential backoff. If `list_products` hits a threshold during a massive sync, the engine pauses and tries again.

Mastra auto-detects between Streamable HTTP and SSE. You just provide the URL and the client handles the underlying connection.
