How to Use the EOD Historical Data MCP in Mastra AI

Q: Can I require manual approval before executing trades based on EOD Historical Data in Mastra AI?

Yes, you configure requireToolApproval in your Mastra agent when calling sensitive tools like getscreener. This pauses the workflow and waits for a human operator to verify the filtered stock list before proceeding to the next step.

Q: How do I register the EOD Historical Data MCP Server tools within a Mastra agent?

You instantiate the MCPClient with your Vinkius HTTP URL, call mcpClient.listTools(), and spread the returned tools directly into your Mastra agent's tool array. The framework automatically handles the underlying transport protocol.

Q: How does Mastra handle large payloads from bulk fundamental queries?

When you call getbulkfundamentals, Mastra processes the massive JSON payload within its workflow state, allowing you to map, filter, and reduce the data before passing it to downstream agents.

Build resilient stock screening workflows with Mastra AI

The `get_screener` tool filters the entire global market based on custom financial metrics and technical signals. Mastra AI executes this tool inside its workflow engine, letting you build multi-step pipelines that automatically branch based on the returned stock list. If the initial query fails due to network hiccups, Mastra's built-in exponential backoff retries the request automatically. This ensures your automated stock screeners run reliably without manual intervention or script crashes.

Execute logic-branched sentiment analysis via MCP Server

The `get_sentiments` tool retrieves news sentiment scores for specific tickers to gauge market mood. Your Mastra AI agent uses this MCP server to trigger conditional branches, such as routing to `get_insider_transactions` if sentiment drops below a specific threshold. You can feed the output of `get_news` into this pipeline to back up the sentiment scores with raw articles. Mastra manages the entire state machine, passing data between these tools while handling rate limits gracefully.

Track macro economic indicators in production

The `get_ust_yield_rates` tool fetches current US Treasury yield curve data to monitor macro market shifts. Your Mastra workflows can compare these yields against `get_ust_bill_rates` to detect yield curve inversions automatically. This workflow can run as a cron job, deploying with a single command to your cloud provider. Mastra handles the scheduling and executes conditional alerts if treasury yields cross critical thresholds.

Setup guide

Set up EOD Historical Data 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 EOD Historical Data 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: "eod-historical-data-mcp-client",
  servers: {
    "eod-historical-data-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about EOD Historical Data MCP in Mastra AI

You rely on Mastra's built-in retry engine with exponential backoff to recover from temporary network issues. If a call to `get_eod_historical` fails, the workflow manager retries the request automatically before triggering any failure branches.

Yes, you configure `requireToolApproval` in your Mastra agent when calling sensitive tools like `get_screener`. This pauses the workflow and waits for a human operator to verify the filtered stock list before proceeding to the next step.

You instantiate the `MCPClient` with your Vinkius HTTP URL, call `mcpClient.listTools()`, and spread the returned tools directly into your Mastra agent's tool array. The framework automatically handles the underlying transport protocol.

When you call `get_bulk_fundamentals`, Mastra processes the massive JSON payload within its workflow state, allowing you to map, filter, and reduce the data before passing it to downstream agents.

Your EOD Historical Data API key and ticker queries, such as those passed to `get_id_mapping`, are transmitted securely via HTTPS and never cached on the MCP server layer. The execution environment is completely ephemeral and isolates your financial data from other tenants.
