Common questions

Is Coinvoyage safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: COINVOYAGE_API_KEY, COINVOYAGE_API_SECRET

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

coinvoyage-paykit-claudeplugin

Claude Code plugin for integrating CoinVoyage — a non-custodial, multi-chain crypto payment gateway — into any app you build with Claude.

Bundles two surfaces:

Skill (`coinvoyage-payments`) — triggers whenever Claude is helping with crypto payments, checkout, stablecoins, or web3 payment work. Guides the integration end to end: server-side PayOrder creation, React PaymentWidget, webhook signature verification, and REST API fallback for non-JS stacks.
MCP server (`@kingpeque/coinvoyage-mcp`) — gives Claude 15 tools for calling the CoinVoyage API directly: create PayOrders, check status, manage webhooks, get swap quotes, and more.

Community-maintained integration. Not officially affiliated with CoinVoyage.

Install

/plugin install KingPeque/coinvoyage-paykit

You'll be prompted at install for:

Field	Required	Notes
`api_key`	yes	Your public API key from https://dashboard.coinvoyage.io → Developers
`api_secret`	optional	Needed for SALE/REFUND orders, webhook management, and fee claims. Leave blank to restrict Claude to read + DEPOSIT flows only.
`api_base_url`	optional	Defaults to `https://api.coinvoyage.io`

The secret is stored in your system keychain via Claude Code's sensitive-config pathway — it never lands in a file you'd commit.

What you can now say to Claude

Once installed, these kinds of requests will activate the skill and/or MCP tools:

"Add crypto payments to my Next.js checkout"
"I want to accept Bitcoin on from my site"
"Build a donation page that takes any crypto while I settle to USDC on base"
"Create a $25 test invoice and settle to USDC on Base heres my wallet"
"Register a webhook at https://mysite.com/api/webhooks/coinvoyage for completed orders"

Supported chains

Bitcoin, Solana, Ethereum, Optimism, Arbitrum, Base, BSC, Polygon, Sui — plus any ERC-20 / SPL / native token on these chains. See full chain ID reference in the supported_chains MCP tool.

Pricing (CoinVoyage's, not this plugin's)

1.5% per successful payment
0% offramp
Merchants can add a custom percentage fee on top
This plugin is free and MIT-licensed. Volume discounts on CoinVoyage fees: help@coinvoyage.io.

Security posture

No secrets in this repo. Everything sensitive lives in your Claude Code config, injected into the MCP server at runtime.
Per-user keys. Every builder uses their own CoinVoyage API key. Nothing is centrally hosted; there's no shared server to compromise.
Minimal network surface. The MCP server only talks to api.coinvoyage.io (or your configured override).
HMAC-SHA256 authentication for privileged operations (SALE/REFUND/webhooks/fee claims).
Open source. Read the MCP server source at mcp-server/src/index.ts — it's under 300 lines.

Local development

git clone https://github.com/KingPeque/coinvoyage-paykit

cd coinvoyage-paykit/mcp-server npm install npm run build

Point your MCP client at ./mcp-server/dist/index.js with COINVOYAGE_API_KEY set

Run the skill locally by symlinking skills/coinvoyage-payments/ into ~/.claude/skills/ (or installing the plugin in dev mode).
