PayU Docs

PayU Developer MCP

Search PayU documentation, browse the payment integration catalog, and fetch production-ready code — directly from your AI assistant.

This is PayU’s developer documentation MCP server. It helps you integrate PayU payments (checkout, UPI, cards, webhooks, refunds, and more) without leaving Cursor, VS Code, or Claude.

Getting Started

Setup Instructions

Add PayU Developer MCP to Cursor

Add PayU Developer MCP to VS Code

OR

Manual setup: Update your mcp.json configuration file (for Cursor: ~/.cursor/mcp.json) with:

{
  "mcpServers": {
    "payu-developer-mcp": {
      "type": "http",
      "url": "https://ask-ai-mcp-710575177112.asia-south1.run.app/mcp"
    }
  }
}

With an API key (higher rate limits):

{
  "mcpServers": {
    "payu-developer-mcp": {
      "type": "http",
      "url": "https://ask-ai-mcp-710575177112.asia-south1.run.app/mcp",
      "headers": {
        "x-api-key": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Save the file and reload your editor to activate the integration.

For Claude Desktop / Pro Users

1. Open Claude Desktop
2. Go to Settings → Connectors → Add custom connector
3. Name: PayU Developer MCP (or any name you prefer)
4. URL: https://ask-ai-mcp-710575177112.asia-south1.run.app/mcp
5. If you have an API key, configure the x-api-key header in your client’s advanced settings
6. Save and restart Claude

Other MCP Clients

{
  "mcpServers": {
    "payu-developer-mcp": {
      "type": "http",
      "url": "https://ask-ai-mcp-710575177112.asia-south1.run.app/mcp"
    }
  }
}

API key (optional)

You can use the server without an API key on the anonymous tier:

• 30 requests / minute
• 100 requests / day

For higher limits, email ai-admin@payu.in to request an API key, then add it as the x-api-key header in your MCP client config (see manual setup below).

No OAuth is required for this developer-docs server.

Workflows You Can Try

Integration Discovery

Find the right PayU integration for your stack

I need to accept UPI payments on my React Native app. Browse the PayU integration
catalog for UPI options on React Native and show me what's available (Hosted vs SDK vs API).

Fetch Integration Code

Get copy-paste snippets for your language and platform

Give me PayU Core SDK integration code for Android in Kotlin using the SDK resource type.
Include setup steps and the main payment initiation snippet.

Web Checkout (Hosted)

Stand up PayU Hosted Checkout on a website

I'm building a Node.js website and want PayU Hosted Checkout for cards and UPI.
Show me the integration catalog entry for Web + PayU Hosted, then fetch JavaScript
integration code I can use in my backend and frontend.

Merchant-Hosted / API Flow

Server-side payment APIs without the hosted UI

Explain the difference between PayU Hosted and Merchant Hosted checkout. Then fetch
PHP API integration code for creating a payment request with hash generation.

Webhooks & Post-Payment

Understand callbacks and verification

How does PayU's payment webhook work? What events are sent, how do I verify the hash,
and what should my idempotent handler do on success vs failure?
Search the docs and summarize with links.

Refunds & Settlements

Operational flows after go-live

Walk me through PayU's refund API: required parameters, sync vs async behavior,
and common error codes. Pull relevant doc sections.

Compare Payment Modes

Pick between Net Banking, EMI, Wallets, etc.

I want Net Banking with TPV on Web. Search the catalog for Net Banking integrations,
then get curl examples for the API resource type so I can test in Postman first.

Multi-Platform (Flutter)

Same product, mobile framework

List Flutter integrations available for Cards and EMI. Then get Dart/Flutter SDK
snippets for EMI on Android and iOS.

Supported Features

Documentation Search

Semantic search across PayU’s official developer docs.

Conceptual guides — Payment flows, webhooks, 3DS, refunds, error handling, and API reference topics

Natural-language queries — Ask in plain English; the server returns relevant excerpts with source URLs

Integration Catalog

Discover what PayU supports before you write code.

Browse by product — UPI, Net Banking, EMI, Cards, Tokenization, Core SDK, and more

Filter by platform — Web, iOS, Android, React Native, Flutter, Cordova, or pure API

Filter by integration type — PayU Hosted, Merchant Hosted, API, or SDK

Integration Code

Production-ready snippets matched to your stack.

Multi-language — curl, PHP, JavaScript, Java, Python, Swift, Objective-C, Kotlin, React JS

Copy-paste ready — Hosted checkout, merchant-hosted, and API examples with doc links

Scored results — Best-matching pages returned with URLs for deeper reading

Available Tools

Recommended workflow

1. Call get_payu_integration_catalog to see valid platform / language / type combinations.
2. Call get_payu_integration_code with your product, platform, language, and resource type.
3. Call search_payu_docs for conceptual questions (flows, webhooks, errors, etc.).

Tips for Best Results

• Start with the catalog — Call get_payu_integration_catalog before get_payu_integration_code so platform, language, and resource type are valid.
• Be specific — Include product (e.g. "UPI Collect", "Core SDK"), platform (Web, Android, …), and language (javascript, kotlin, …).
• Use doc search for "why" — Flows, compliance, webhooks, and troubleshooting → search_payu_docs.
• Use code fetch for "how" — Implementation snippets → get_payu_integration_code.
• Request an API key for heavy use — Anonymous limits are fine for exploration; production or team usage should use x-api-key.

Important Notes

⚠️ Developer docs only — This server does not create payment links, run transactions, or access your merchant dashboard. Use the merchant MCP for those operations.

⚠️ Rate limits — Anonymous usage is capped at 30 req/min and 100 req/day. Contact ai-admin@payu.in for a key if you hit limits.

⚠️ Verify in dashboard — Always confirm credentials, salt, and environment (test vs production) in the PayU Dashboard before going live.

⚠️ Docs are authoritative — Snippets are sourced from PayU documentation; re-check hash algorithms, endpoints, and field names against the latest docs before production deploys.
