How to Use the Capsulink MCP in Mastra AI

Q: Can a mastra-ai workflow automatically shorten links using Capsulink?

Yes, you can include shortenurl as a step in any Mastra workflow. For example, when a new blog post is published, the agent generates the short link and passes it to your social media step.

Build automated workflows that shorten URLs and monitor click performance using Mastra AI agents.

Automated Link Swapping on Failure

The `edit_link_destination` tool lets your Mastra AI agent update target URLs automatically when a downstream service goes down. If a monitor step in your workflow detects a 500 error on a landing page, the agent swaps the destination to a backup URL. Because Mastra handles multi-step workflows, you can chain this with notification tools. The agent fixes the link first, then pings your team to let them know a swap occurred.

Scheduled Analytics Sweeps via Mastra AI

The `get_link_stats` tool pulls total click counts into your automated cron workflows. You can set a Mastra agent to run every Monday morning, fetch the performance of your top links, and compile a summary. By using `list_link_folders` alongside this, the agent can organize reports by campaign. You get structured data without writing custom API integration glue code.

Self-Cleaning Link Directories

The `delete_link` tool allows your workflow to purge temporary or expired marketing links after a specific promotion ends. Your agent checks the expiration status and deletes the link to prevent clutter. This MCP Server also provides `list_links` so the agent can scan your entire catalog before deciding which ones to prune. It keeps your Capsulink account organized without human oversight.

Setup guide

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

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

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

Common questions about Capsulink MCP in Mastra AI

Instantiate the MCP client using your Vinkius endpoint URL. Then, pass the tools retrieved from `listTools` directly into your Mastra agent's tool array.

Yes, you can include `shorten_url` as a step in any Mastra workflow. For example, when a new blog post is published, the agent generates the short link and passes it to your social media step.

Mastra's built-in retry engine handles network glitches automatically. If `get_link_daily_stats` fails, the workflow retries with exponential backoff before triggering any failure paths.

No, you don't. Vinkius manages the authentication layer, meaning your Mastra configuration only needs to point to your secure Vinkius endpoint.

Every link path and folder name is processed inside ephemeral V8 isolates. Your link configuration data is never stored outside your active execution context.
