Perplexity

Automate complex literature reviews

Mastra AI agents use `search_works` to build autonomous research pipelines. You set up a workflow where the agent looks for specific keywords, filters by publication date, and evaluates the abstracts. If a query fails or times out, Mastra's built-in exponential backoff catches the error and tries again. You get a reliable agent that grinds through thousands of academic papers without manual supervision.

Mastra AI MCP Server branching

Conditional logic makes `get_work` and `get_member` incredibly powerful. Your agent pulls an article by DOI, reads the publisher ID, and then branches the workflow based on whether that publisher is open access. A separate branch can trigger `get_licenses` to verify the copyright status. The workflow engine handles all the routing, letting you build a compliance checker that runs entirely on autopilot.

Map journals and funding sources

Discovering institutional relationships starts with `search_funders` and `search_publishers`. The agent feeds a university name into the tool and extracts the exact IDs and work counts for that organization. From there, it calls `get_journal` to list every publication tied to that funder. You deploy this to your cloud provider with one command, creating a permanent monitor for institutional research output.

Setup guide

Set up CrossRef Alternative 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 CrossRef Alternative 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: "crossref-alternative-mcp-client",
  servers: {
    "crossref-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent CrossRef Alternative transactions"
);
console.log(result.text);

Common questions about CrossRef Alternative MCP in Mastra AI

Install @mastra/mcp and instantiate a new MCPClient. Pass the Vinkius URL in the servers object under your chosen name. Then call listTools() and spread the results into your agent's toolkit.

The framework automatically handles transient failures when fetching academic metadata. If a get_works_by_doi_list request drops, the workflow engine applies exponential backoff and retries the exact same DOIs.

You can easily flag any citation tool with requireToolApproval. The workflow will pause before executing search_works, letting a researcher review the query parameters before the agent proceeds.

Mastra auto-detects the correct protocol during connection. The Vinkius endpoint provides a Streamable HTTP connection, which the client configures without any manual transport setup on your end.

Your specific search terms, author names, and DOI lists remain completely isolated. The Vinkius zero-trust architecture executes the Mastra AI request in an ephemeral sandbox that vaporizes the moment the journal metadata ships back to your workflow.
