Call start_here first for three no-auth examples. Browse with voidpay_services, then read a known published storefront; signing and payment stay with the owner.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http voidpay-mcp https://api.voidly.ai/mcp/voidpay

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add voidpay-mcp --url https://api.voidly.ai/mcp/voidpay

Cursor

Merge this server into .cursor/mcp.json in your project, then enable voidpay-mcp in your MCP settings.
