Plaid Integration

The Plaid integration provides access to manage Plaid create link token, exchange public token, get accounts, get transactions, get identity through the Integrate MCP server.

Installation

The Plaid integration is included with the SDK:

import { plaidIntegration } from "integrate-sdk/server";

Setup

1. Create a Plaid OAuth App

1. Create an OAuth application for Plaid
2. Configure your redirect URI
3. Note your Client ID and Client Secret

2. Configure the Integration on Your Server

Add the Plaid integration to your server configuration. The integration automatically reads PLAID_CLIENT_ID and PLAID_CLIENT_SECRET from your environment variables:

import { createMCPServer, plaidIntegration } from "integrate-sdk/server";
 
export const { client: serverClient } = createMCPServer({
  apiKey: process.env.INTEGRATE_API_KEY,
  integrations: [
    plaidIntegration({
      scopes: ["transactions", "auth", "identity", "accounts", "investments", "liabilities"], // Optional
    }),
  ],
});

You can override the environment variables by passing explicit values:

plaidIntegration({
  clientId: process.env.CUSTOM_PLAID_ID,
  clientSecret: process.env.CUSTOM_PLAID_SECRET,
      scopes: ["transactions", "auth", "identity", "accounts", "investments", "liabilities"], // Optional
});

3. Client-Side Usage

The default client automatically includes all integrations. You can use it directly:

import { client } from "integrate-sdk";
 
await client.authorize("plaid");
const result = await client.plaid.createLinkToken({
  link_token_json: "value",
});
 
console.log(result);

If you're using a custom client, add the integration to the integrations array:

import { createMCPClient, plaidIntegration } from "integrate-sdk";
 
const customClient = createMCPClient({
  integrations: [plaidIntegration()],
});

Configuration Options

export interface PlaidIntegrationConfig {
  clientId?: string;

Default Scopes

These defaults are applied unless you override scopes in the integration config:

• transactions
• auth
• identity
• accounts
• investments
• liabilities
