Perplexity

Mastra AI agent logic for nonprofits

Link `search_grants` to your Mastra AI agent memory to automate research pipelines. You can set conditional branches that trigger only when specific grant criteria are met. It handles the retry logic for you. If a lookup for `get_grant_details` fails, the agent manages the recovery automatically.

Real-time compliance monitoring

Use `verify_charity_status` within your Mastra AI workflows to ensure every nonprofit partner remains eligible. It acts as a safety gate for your automated operations. If the status changes, the agent can alert your team immediately. It moves the burden of verification from your staff to the agent framework.

Deep nonprofit financial analysis

Deploy `get_nonprofit_premier` to fetch granular data for your agent to process. Your Mastra AI agent can synthesize this information into reports without human input. It works by pulling exact financial figures via EIN. You gain a clear picture of an organization's health without manual data entry.

Setup guide

Set up Candid (GuideStar) 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 Candid (GuideStar) 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: "candid-guidestar-mcp-client",
  servers: {
    "candid-guidestar-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Candid (GuideStar) MCP in Mastra AI

You instantiate the client and spread the tools into your agent definition. It takes one line of code to make your Mastra AI agent aware of all 10 available tools.

Absolutely. You can schedule a workflow that runs `search_grants` daily. The agent then filters the results based on your custom logic.

Because it integrates directly into the workflow engine, you can define custom failure handlers. If a tool request times out, the agent tries again or flags it for your review.

We enforce strict transport security for every request. Your agent communicates through a dedicated tunnel that keeps your data isolated from other users.

The server handles nonprofit tax IDs, donation eligibility status, and foundation grant details. We secure this by encrypting all traffic in transit and purging request logs after the agent task completes.
