Perplexity

Reliable expression parsing for Mastra AI agents

Agents often fail when calculating multi-step variables. Use `calculate_expression` within your Mastra workflow to ensure the agent logic follows hard math, not probability. It acts as a truth anchor for your automated tasks. If an agent needs to verify a total before triggering a webhook, this tool provides the definitive answer.

Consistent rounding for automated reports

Your workflows need predictable outputs for downstream systems. The `round_value` tool forces consistency across your pipeline, ensuring every agent sees the same number. It eliminates the drift that occurs when different agents round values differently. You set the precision once, and the engine enforces it.

Workflow integration without extra code

Mastra AI discovers these tools automatically. You just list them as agent capabilities, and your workflow logic can call them whenever an arithmetic gate appears. It simplifies your agent definitions. You stop writing custom math helpers and rely on the specialized server instead.

Setup guide

Set up Math Evaluation Engine 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 Math Evaluation Engine 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: "math-evaluation-engine-mcp-client",
  servers: {
    "math-evaluation-engine-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Math Evaluation Engine MCP in Mastra AI

You define the server URL in your Mastra MCP configuration. The framework then exposes the tools for your agents to use in their tasks.

No. The execution time is sub-10ms. It is significantly faster than asking an LLM to perform mental math.

Yes. You can route your workflow path based on the output of the tool. If the math hits a specific threshold, the agent executes the next step.

That depends on your agent setup. You can flag the tool call for manual review if your workflow requires a human to verify the output.

Your input expressions are processed in an isolated memory sandbox. The server does not retain or log any arithmetic input.
