Perplexity

Execute multi-step content logic

Mastra AI agents can now chain `list_object_types` and `create_object` calls to build your site structure dynamically. If a step fails, your workflow engine handles the retry. This setup keeps your content pipeline moving even when external conditions fluctuate. You define the branching logic, and the tools perform the actual writes.

Handle CMS failures automatically

Use `update_object` within your Mastra AI workflows to ensure your CMS stays in sync with your app state. You can set up exponential backoff for every tool call. Your agent doesn't just push data; it verifies the state after each step. If a write fails, the workflow catches it instantly.

Monitor agent conversations

Access your logs with `get_agent_conversation_history` to see exactly how your agent interacted with the CMS. You can debug your workflows by replaying these sequences. Seeing the full history helps you tune your prompts for better accuracy. It makes your agent's decision-making process transparent.

Setup guide

Set up Cosmic (Headless CMS & Content API) 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 Cosmic (Headless CMS & Content API) 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: "cosmic-headless-cms-content-api-mcp-client",
  servers: {
    "cosmic-headless-cms-content-api-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Cosmic (Headless CMS & Content API) transactions"
);
console.log(result.text);
