Nothing serious here today

Today is the operative word: we check payware every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

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.

run in your terminal
claude mcp add mcp-server -- npx -y @payware/mcp-server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-server": {

This one needs environment variables set before it will start: PAYWARE_PARTNER_TYPE (Partner role: merchant, isv or payment_institution), PAYWARE_PARTNER_ID (Partner ID from the payware dashboard), PAYWARE_SANDBOX_PRIVATE_KEY_PATH (Path to the RSA private key for the sandbox), PAYWARE_PRODUCTION_PRIVATE_KEY_PATH (Path to the RSA private key for production), PAYWARE_OAUTH_CLIENT_ID (OAuth2 client ID (ISV partners only)), PAYWARE_OAUTH_CLIENT_SECRET (OAuth2 client secret (ISV partners only)). The author declared them in the registry entry; get the values from the project itself.

payware — questions

Answers built from our own checks of this server.

Why is there no uptime for payware?
payware 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 @payware/mcp-server was installed 85 times last week.
How do I connect payware?
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 @payware/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use payware?
The npm package @payware/mcp-server was installed 85 times in the last week. Week over week that is +168%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is payware open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
