This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: NUPAY_MERCHANT_KEY (NuPay X-Merchant-Key issued to your merchant), NUPAY_MERCHANT_TOKEN (NuPay X-Merchant-Token issued to your merchant), NUPAY_CLIENT_ID (OAuth2/CIBA client_id for pre-authorized (recurrence) flows. Optional unless using backchannel_start / backchannel_complete.), NUPAY_CLIENT_SECRET (OAuth2/CIBA client_secret for pre-authorized flows. Optional unless using backchannel_* tools.), NUPAY_ENV (sandbox | production. Defaults to sandbox. Drives both checkout API and auth base URLs.). The author declared them in the registry entry; get the values from the project itself.

MCP Nupay — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Nupay?
MCP Nupay runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @codespar/mcp-nupay was installed 27 times last week.
How do I connect MCP Nupay?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @codespar/mcp-nupay straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Nupay?
The npm package @codespar/mcp-nupay was installed 27 times in the last week. Week over week that is +238%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Nupay open source?
Yes — it is published under the MIT licence, written in TypeScript, 271 stars on GitHub and 8 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
