Automated chart creation in Mastra AI

Add `generate_chart_url` to your agent tools to automate report generation. It creates a simple link you can pass through your workflow steps. If the step fails, your agent can retry the request automatically. This keeps your pipeline moving without manual intervention or constant oversight.

Robust POST rendering for complex workflows

For deep data analysis, call `render_chart_post` to get the image bytes back as a Base64 string. This is the right choice for high-cardinality charts that don't fit in a standard URL. It integrates with your existing Mastra AI error handling. If a payload is too big, the tool provides a clean path to get the image rendered safely.

Control tool access with Mastra AI

Use the built-in `requireToolApproval` to verify chart generation before the agent executes the call. It puts a human in the loop for sensitive data outputs. This MCP Server plugs into your agent definition as a native toolset. It keeps your code clean and your agent logic focused on the task at hand.

Setup guide

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

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

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

Common questions about Image-Charts MCP in Mastra AI

Import the MCP client and register the server URL in your agent config. You can then list the tools and assign them to your workflow steps.

They are. By using the POST tool for large data, you prevent truncation errors and ensure the agent always receives the complete chart image.

It does. If a network blip occurs during a chart request, the framework handles the retry logic, and the tool completes the task as expected.

The server only touches the specific data you pass for chart rendering. All interactions are stateless and isolated within the Vinkius environment.

Use an endpoint token provided by Vinkius. This ensures that only your authorized agents can trigger chart generation.
