Pay MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Pay MCP?
Pay MCP 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 @vauban-org/pay-mcp was installed 1 115 times last week.
How do I connect Pay MCP?
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 @vauban-org/pay-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Pay MCP?
The npm package @vauban-org/pay-mcp was installed 1 115 times in the last week. Week over week that is +746%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
