Find answers to common questions about the Pine Labs Online MCP Server, grouped by category.

## Requirements

<details>
<summary><b>What is MCP?</b></summary>

<br/>**Model Context Protocol (MCP)** is an open standard that lets AI assistants call external tools and APIs in a structured way. Think of the Pine Labs Online MCP Server as a translator: your AI assistant speaks MCP, and the server converts those calls into Pine Labs Online API requests.

</details>

***

<details>
<summary><b>Which protocol does the server use?</b></summary>

<br/>It exposes a **Streamable HTTP** endpoint at `/mcp`. The `mcp-remote` npx package handles the client-side transport.

</details>

***

## Integration

<details>
<summary><b>Are my credentials stored on the server?</b></summary>

<br/>**No.** Your `X-Client-Id` and `X-Client-Secret` travel in the request headers and are forwarded directly to the Pine Labs API. Nothing is persisted on the MCP server.

</details>

***

<details>
<summary><b>Which environment should I use?</b></summary>

<br/>

| When | Use |
| :--- | :--- |
| Building and testing | **UAT** — sandbox data, no real charges |
| Going live | **Production** — real transactions |

</details>

## Testing

<details>
<summary><b>Which payment methods can be offered through a payment link?</b></summary>

If you don't specify, all methods are shown by default.

</details>

***

<details>
<summary><b>How should the amount be specified?</b></summary>

<br/>Amounts must be provided in **paisa** (the smallest unit of INR).

| Rupees | Paisa |
| :--- | :--- |
| ₹1 | **100** |
| ₹500 | **50,000** |
| ₹1,000 | **1,00,000** |

Valid range: `100` (₹1) to `1,00,00,000` (₹10,00,000).

</details>

***

## Compatibility

<details>
<summary><b>Does the server support OAuth?</b></summary>

<br/>**No**, OAuth is not supported at this time. Authentication is performed using the `X-Client-Id` and `X-Client-Secret` headers provided with your Pine Labs Online merchant account.
