Perplexity

Fault-Tolerant Risk Pipelines

You build complex patient assessment workflows that won't break if one step fails. If the initial scoring attempt doesn't work, Mastra can automatically retry with a different method or alert an admin. This reliability is key when you need to process sensitive data like stroke and bleeding risk scores.

Structured Assessment using MCP Server

The tool `query_cha2ds2_vasc_score` calculates the AFib score, which can then feed into a conditional branch. If the score is above a certain threshold, your workflow automatically triggers the next step. This makes sense for clinical logic; you don't want to manually check every boundary condition.

Managing Complex Outcomes

The system handles sequencing: first, run `calculate_hasbled_score` to assess bleeding. Second, use the AFib score and then let the tool `get_risk_recommendations` determine the final treatment plan. It's built for workflows that need clear success or failure paths.

Setup guide

Set up CHA₂DS₂-VASc & HAS-BLED Calculator 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 CHA₂DS₂-VASc & HAS-BLED Calculator 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: "cha2ds2-vasc-has-bled-calculator-mcp-client",
  servers: {
    "cha2ds2-vasc-has-bled-calculator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "CHA₂DS₂-VASc & HAS-BLED Calculator Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to CHA₂DS₂-VASc & HAS-BLED Calculator tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent CHA₂DS₂-VASc & HAS-BLED Calculator transactions"
);
console.log(result.text);
